Neoseeker tested out the 4 core Ryzen 5 1400 and 6 core 1600 model to see how they stack up against other lower cost processors. They ran the tests at the highest stable overclock they could reach, interestingly both were able to hit a 3.8 GHz base clock, paired with DDR4-2400. The processors were cooled with AMD's Wraith Max cooler so it is possible to push these CPUs further if you are willing to overvolt. Drop by to see how these two processor match up to the competition.
"The two AMD processors for review today are the newest budget offerings of the Ryzen 5 series with the Ryzen 1400 and 1600 models. The Ryzen 1400 is a four core/eight thread and the Ryzen 1600 is a six core/twelve thread processor, with both having a base operating speed of 3.2 GHz. The boost clock for the Ryzen 1400 is 3.4 GHz while the Ryzen 1600 is able to boost to 3.6 GHz."

Tagged: Zen, Vega, ryzen mobile, ryzen, raven ridge, APU, amd
AMD teased its upcoming Zen-based APUs aimed at mobile devices during its Financial Analyst Day where the company revealed the "Raven Ridge" parts will be aptly known as Ryzen Mobile. The Tech Report managed to acquire a couple slides which confirm some of the broader specifications and reveal how they stack up to AMD's latest Bristol Ridge A-Series APUs – at least as far as AMD's internal testing is concerned (which is to say not independently verified yet so take with a grain of salt).
Ryzen Mobile appears to be the new consumer-facing brand name for what has so far been code named "Raven Ridge". These parts will use a Zen-based CPU, Vega GPU, and integrated chipset. Thanks to the slides, it is now confirmed that the Vega-based graphics processor will be on-die. What has not been confirmed is whether the chipset will be on die or on package and exact specifications on CPU cores counts, GPU Compute Units, cache, memory support, and I/O like PCI-E lanes (you know, all the good stuff! heh). Note that rumors so far point towards Raven Ridge / Ryzen Mobile utilizing a single 4-core (8-thread) CCX, per core L2, 8MB shared L3 cache, and a Vega-based GPU with 1024 cores. HBM2 has also been rumored for awhile but we will have to wait for more leaks and/or an official announcement to know for sure if these Ryzen Mobile parts aimed for the second half of 2017 will have that (hopefully!).
With that said, according to AMD, Ryzen Mobile will offer up to 50% better CPU performance, 40% better GPU performance, and will use up to 50% less power than the previous 7th generation (Excavator-based) A-Series APUs (e.g. FX 9830P and A12-9730P). Those are some pretty bold claims, but still within the realm of possibility. Zen and Vega are both much more efficient architectures and AMD is also benefiting from a smaller process node (TSMC 28nm vs Samsung / GlobalFoundries 14nm FinFET). I do wonder how high the APUs will be able to clock on the CPU side of things with 4 GHz seeming to be the wall for most Zen-based Summit Ridge chips, so most of the CPU performance improvement claims will have to come from architecture changes rather than increases in clockspeeds (the highest clocked A-Series Bristol Ridge ran at up to 3.7 GHz and I would expect Raven Ridge to be around that, maybe the flagship part turbo-ing a bit more). Raven Ridge will benefit from the shared L3 cache and, more importantly, twice as many threads (4 vs 8) and this may be where AMD is primarily getting that 50% more CPU performance number from. On the graphics side of things, it looks like Bristol Ridge with its R7 graphics (GCN 3 (Tonga/Fiji on the Desktop)) had up to 512 cores. Again, taking the rumors into account which say that Raven Ridge will have a 1024 core Vega GPU, this may be where AMD is getting the large performance increase from (the core increase as well as newer architecture). On the other hand, the 40% number could suggest Ryzen Mobile will not have twice the GPU cores. I would guess that 1024 might be possible, but running at lower clocks and that is where the discrepancy is. I will admit I am a bit skeptical about the 1024 (16 CU) number though because that is a huge jump... I guess we will see though!
Further, I am curious if Ryzen Mobile will use HBC (high bandwidth cache) and if HBM2 does turn out to be utilized how that will play into the HBC and whether or not we will finally see the fruits of AMD's HSA labors! I think we will see most systems use DDR4, but certainly some SKUs could use HBM2 and that would definitely open up a lot of performance possibilities on mobile!
There is still a lot that we do not know, but Ryzen Mobile is coming and AMD is making big promises that I hope it delivers on. The company is aiming the new chips at a wide swath of the mobile market from budget laptops and tablets to convertibles and even has their sights set on premium thin and lights. The mobile space is one where AMD has struggled with in getting design wins even when they had good parts for that type of system. They will really need to push and hit Ryzen Mobile out of the park to make inroads into the laptop, tablet, and ultrabook markets!
AMD plans to launch the consumer version of Ryzen Mobile in the second half of this year (presumably with systems featuring the new APUs out in time for the holidays if not for the back to school end of summer rush). The commercial SKUs (which I think refers to the Ryzen equivalent of AMD Pro series APUs.Update: Mobile Ryzen Pro) will follow in the first half of 2018.
What are your thoughts on Ryzen Mobile and the alleged performance and power characteristics? Do you think the rumors are looking more or less correct?

AMD has formally announced their EPYC CPUs. While Sebastian covered the product specifications, AMD has also released performance claims against a pair of Intel’s Broadwell-E Xeons. While Intel’s E5-2650 v4 processors have an MSRP of around $1170 USD, each, we don’t know how that price will compare to AMD’s offering. At first glance, pitting thirty two cores against two twelve-core chips seems a bit unfair, although it could end up being a very fair comparison if the prices align.

Patrick Moorhead, who was at the event, tweeted out photos of a benchmark where Ubuntu was compiled over GCC. It looks like EPYC completed in just 33.7s while the Broadwell-E chip took 37.2s (making AMD’s part ~9.5% faster). While this, again, stems from having a third more cores, this depends on how much AMD is going to charge you for them, versus Intel’s current pricing structure.

This one chip also has 128 PCIe lanes, rather than Intel’s 80 total lanes spread across two chips.

AMD revealed their entry into high-end desktop (HEDT) with the upcoming Ryzen "Threadripper" CPUs, which will feature up to 16 cores and 32 threads.
Little information was revealed along with the announcement, other than to announce availablility as "summer 2017", though rumors and leaks surrounding Threadripper have been seen on the internet (naturally) leading up to today's announcement, including this one from Wccftech. Not only will Threadripper (allegedly) offer quad-channel memory support and 44 PCI Express lanes, but they are also rumored to be released in a massive 4094-pin package (same as "Naples" aka EPYC) that most assuredly will not fit into the AM4 socket.

These Threadripper CPUs follow the lead of Intel's HEDT parts on X99, which are essentially re-appropriated Xeons with higher clock speeds and some feature differences such as a lack of ECC memory support. It remains to be seen what exactly will separate the enthusiast AMD platform from the EPYC datacenter platform, though the rumored base clock speeds are much higher with Threadripper.

AMD has announced their new datacenter CPU built on the Zen architecture, which the company is calling EPYC. And epic they are, as these server processors will be offered with up to 32 cores and 64 threads, 8 memory channels, and 128 PCI Express lanes per CPU.
Some of the details about the upcoming "Naples" server processors (now EPYC) were revealed by AMD back in March, when the upcoming server chips were previewed:
- A highly scalable, 32-core System on Chip (SoC) design, with support for two high-performance threads per core
- Industry-leading memory bandwidth, with 8-channels of memory per "Naples" device. In a 2-socket server, support for up to 32 DIMMS of DDR4 on 16 memory channels, delivering up to 4 terabytes of total memory capacity.
- The processor is a complete SoC with fully integrated, high-speed I/O supporting 128 lanes of PCIe, negating the need for a separate chip-set
- A highly-optimized cache structure for high-performance, energy efficient compute
- AMD Infinity Fabric coherent interconnect for two "Naples" CPUs in a 2-socket system
- Dedicated security hardware
Compared to Ryzen (or should it be RYZEN?), EPYC offers a huge jump in core count and available performance - though AMD's other CPU announcement (Threadripper) bridges the gap between the desktop and datacenter offerings with an HEDT product. This also serves to bring AMD's CPU offerings to parity with the Intel product stack with desktop/high performance desktop/server CPUs.

While specifications were not offered, there have been leaks (of course) to help fill in the blanks. Wccftech offers these specs for EPYC (on the left):

We await further information from AMD about the EPYC launch.

The pricing of AMD's Ryzen 5 line spans from $170 to $250, similar to Intel's Core i5 line and may wwll tempt those a generation or two out of date to consider an upgrade. In order to demonstrate differences in CPU performance Ars Technica tested both Intel and AMD processors paired with a GTX 1080 Ti. By doing so at lower resolutions which the card can more than handle they expose differences in the performance of the two architectures, which seem to follow AMD's offerings into higher resolutions albeit with a smaller performance delta. Check out the wide gamut of tests that were performed to see which architecture makes more sense for your usage, especially if you do more than just gaming and surfing.
"The Ryzen 5 range is made up of four chips. At the top is the £240/$250 Ryzen 5 1600X, a 95W six-core chip that boasts simultaneous multithreading (SMT, the equivalent of hyper-threading), 16MB of L3 cache, and a 3.6GHz base clock."

Tagged: ryzen, amd, 1700X
A little birdie sent me a note this afternoon that the AMD Ryzen 7 1700X processor was selling on Amazon.com for just $333! Considering the launch price of that CPU was $399 just two months ago, a $60-70 discount makes this platform all the more compelling for consumers looking to build a new PC. Coupling that with the overclocking performance we saw from our Ryzen 1700 sample, you should be able to meet or exceed expectations with the 1700X model.
This link led me down a bit of a rabbit hole as I wanted to see where a solid build would stand using that processor and a focus on budget. Now, keep in mind that this was put together rather hastily this afternoon, but here's what I came up with.
|Ryzen 7 1700X Build|
|Processor||AMD Ryzen 7 1700X - $333|
|Cooler||Thermaltake Contac Silent - $24|
|Motherboard||ASUS Prime B350-Plus - $99|
|Memory||G.Skill Ripjaws 16GB DDR4-3000 - $118|
|Graphics Card||EVGA GeForce GTX 1050 Ti 4GB - $149|
|Storage||Samsung 850 EVO 250GB - $107|
|Case||Corsair 200R ATX Mid Tower Case - $56|
|Power Supply||Corsair CX 500 watt - $59|
|Total Price||$945 - Amazon.com Full Cart|
For the base of the system, you can pick up the Ryzen 7 1700X processor for $333, a great B350-based motherboard from ASUS for $99 and 16GB of DDR4 memory running at 3000 MHz for just $118. Getting that memory at higher clock speeds is important for optimal Ryzen performance - hunt around to find the best deal! That's just $550 for the heart of a system that could power anything from the GTX 1050 Ti I included above to the GTX 1080 Ti if you are pushing the limits of graphics performance.
If you try to stay within a reasonable budget, as I did above, you can build a from-scratch machine for under $1000 with some impressive specifications and capabilities. The GTX 1050 Ti will get you peak 1080p gaming capability while the 8-cores and 16-threads of the Ryzen 7 1700X will improve any workstation-class or multimedia workloads.
Separately, but interestingly, the gang at 3DCenter.org posted the results of a survey taken about the Ryzen 5 processor launch, measuring the readers reactions to the release. In it, 83.9% of the audience looked upon the Ryzen 5 favorably, 9.4% as average and 6.7% negatively. If you compare that to the Ryzen 7 launch (74.6% favorable, 17.5% average, 7.9% negative) it seems that Ryzen 5 was better received than its big brother. But if you look back to October 2011 when the same survey was run about AMD Bulldozer, only 6.8% saw the CPU launch as favorable (!!). The last CPU launch that received nearly as positive a reaction as Ryzen 5/7 was the Sandy Bridge CPU back in January of 2011.
Obviously this survey isn't a predictor of success or failure exactly, but it does point to an audience that is incredibly receptive to the new AMD processors. My own experience tells me that these numbers are fairly accurate to the mood about Ryzen, even after the 1080p gaming fiasco that circulates to this day. Interest and reaction are great for a company that needs to make in-roads in the market, but converting that consumer interest into purchases is the key for AMD going forward.

Today Qualcomm took the covers off of an update to the Snapdragon 600 family of processors, now known as mobile platforms. The Snapdragon 660 and 630 Mobile Platforms are important products in the company’s portfolio as they address a larger segment of the consumer market than the premium-tier Snapdragon 800 while still offering performance and feature sets above the budget segments of the 400s. The Snapdragon 820 and 835 traditionally get all of the attention from media, the 600-series is at the heart of popular devices like the Sony Xperia X, Asus Zenfone 3 Ultra, HTC 10 Lifestyle and over 1000 more designs.
The biggest changes to both new platforms come in the form of LTE connectivity and GPU performance. In a bid to bring previously unseen capabilities to the 600-series of solutions, Qualcomm has taken the Snapdragon X12 LTE modem that shipped with the Snapdragon 820/821 SoC and integrated it on both the 660 and 630. This creates mainstream mobile platforms that can run Cat 12/13 modems and speeds as high as 600 Mbps downstream (3x carrier aggregation) and 150 Mbps upstream (2x carrier aggregation).
That is a significant move and should result in a massive amount of high speed devices saturating the market (and carriers’ networks) starting later this year. Along with that higher performance comes the same X12 feature set that we saw with Snapdragon 820/821 including adaptive antenna tuning capability (TruSignal) and dynamic signal quality adjustments for power efficiency optimizations.
The GPU performance of both the Snapdragon 660 and 630 get a boost over the previous competitors (653 and 626 respectively) though they do so with different Adreno implementations. The SD 660 uses the Adreno 512 GPU that offers up to 30% better performance compared to the Adreno 510 used on the SD 650 series. While we don’t have details yet on where that advantage comes from (clocks or core improvements), I have a feeling that much of it comes from improved frequencies. The Snapdragon 630 uses the Adreno 508 GPU, compared to the 506 from the SD 626 processor, and also claims to have a 30% performance advantage over the previous generation.

Delidding a Kaby Lake processor such as the i7-7700k does not offer the same overclocking advantages as with previous generations when replacing the TIM gave you more headroom. Instead of being able to push your CPU past 5GHz, popping the lid off of a Kaby Lake reduces operating temperatures and likely extends the life of the processor ... or immediately ends it. If you don't have a 3D printer handy to make your own delidder, then take a peek at this review from TechPowerUp. They try out two delidding tools, one from Aqua Computer and one from Rockit which Morry has used; do be aware that any CPUs killed as a result of reading their review is the responsibility of the one who delidded.
"Intel mainstream CPUs have had a bottleneck in cooling due to poor heat transfer from the CPU die to the integrated heat spreader. Thanks to new de-lidding friendly tools released recently, it is now easier than ever before to handle this yourself and get a cooler running CPU. We examine two such solutions from Rockit Cool and Aqua Computer today, both of which promise fool-proof de-lidding and re-lidding"

According to DigiTimes, Intel is expecting to release several new processors earlier than they had originally planned. That said, there are two issues with this report. The first point, which should be expected, is that it compares internal dates that were never meant to be public. It is not like Intel has changed their advertised roadmap.
The second problem is that it’s somewhat contradicted by Intel’s earlier, public statements.
Their rumor claims that Intel will push up the launch of Basin Falls, which is Skylake-X, Kaby Lake-X, and X299, by about two months (around June). It also claims that Coffee Lake, which was originally scheduled for January 2018, will be released in August 2017. Both of these moves are being attributed to AMD’s new products.
The potential, somewhat, sort-of contradiction comes from a tweet that Intel made back in February. In it, they said that the 8th generation of Core processors are expected for 2H’17. This time frame doesn’t include January, although it only barely includes August, too. If Intel was always planning on launching Coffee Lake for the “back to school” season, then at least that half of DigiTimes’ story would be completely incorrect. On the other hand, if Intel’s tweet was talking about a sampling / paper launch in December, with volume shipment soon to follow, then DigiTimes would be fairly accurate.
We don’t know unless someone at Intel confirms either-or.
As for Skylake-X and Kaby Lake-X, it would be interesting to see them launch at Computex / E3. Previous rumors (also from DigiTimes) that place it in the Gamescom, which is a huge gaming conference in Cologne. Interestingly, this rumor claims that only the four-, six-, eight-, and ten-core models will arrive at the time, with a twelve-core model waiting until the whole line was supposed to launch.
This omission makes me wonder if, in fact, Intel are rushing the launch, but they realize that they cannot get enough good chips to fill out the top-end SKU. In that case, it would make sense to push the smaller and partially-disabled chips out the door, while banking the big chips that can run all twelve cores at a reasonable voltage for some clock rate.
If so, that would, in fact, speak volumes about AMD’s roadmap (and Intel’s opinion of it).

As you have already read through Ryan's review of the Ryzen 1600X and 1500X running on MSI's B350 Tomahawk you know about how the chips measure up to Intel's offerings at the same price point. Life being what it is, there is always a trade between testing everything and publishing results in a timely manner so it is possible that we missed your favourite game, benchmark or test setting which is why roundups such as this exist. For instance over at [H]ard|OCP the tests were performed on an MSI Krait Z270 Gaming motherboard and they also had a chance to review the $169 Ryzen 5 1400.

AMD Releases Ryzen Balanced Power Plan - Test Results Inside
AMD has published Community Update #3 to their blog. This update details a new Power Plan that should yield improved gaming performance for those who were previously using the Windows default Balanced Power Profile. There has been lots of speculation on reasons for performance differences when gaming in various power modes and even on different Operating Systems. With this new Ryzen Balanced profile also came some info that should help us clear up some of the other misconceptions out there.
After we determined that the Windows 10 Scheduler was not at fault for the Ryzen performance issues we were seeing in some applications, we received some testing feedback from those who had noted performance differences between Windows 7 and Windows 10. While many believed that to be confirmation of scheduler differences between both Operating Systems, the actual cause was down to how Windows 7 and Windows 10 park their cores, as demonstrated by the points AMD sent us earlier today:
- Windows 7 only parks SMT cores, keeping all physical cores awake.
- Windows 10 keeps the first core awake (logical core 0 + 1 on a HT system) and parks the remainder when possible.
- Windows 10 disables core parking by default on Intel CPUs (Speed Shift support).
Since Windows power management (not the scheduler) is not yet Ryzen aware, its default settings result in overly aggressive core parking when driving a Ryzen CPU. Until a lower level change can take place, AMD has released a custom Ryzen Balanced Power Plan that tweaks some of the P-state transition values and a few other settings to help realize the performance gains previously seen by folks shifting to the High Performance mode while keeping idle power consumption much closer to that of the Balanced plan. Here are AMD’s claimed performance gains (vs. Balanced) with their new Ryzen Balanced Power Plan:
AMD provided claimed gains for Ryzen Balanced profile vs. default Windows Balanced profile.
Realize these gains are all going to be nearly identical to any prior comparison showing Balanced vs. High Performance profile deltas, but this profile retains most of the idle power savings accomplished by the Balanced plan. We’ve been doing some testing with the tool and can partially confirm the above results, while adding in some more of our own that were not included in AMD’s data:
The blue highlighted bars denote the overlapping titles tested. A few other titles we tested showed lesser (or no) gains, but that’s not necessarily the fault of this new profile as those same titles saw similar results with a switch to High Performance mode when tested previously.
I did a bit of digging into exactly which power profile parameters are being tweaked and how. Laymen poking around in Windows Power Management will only find this single difference:
However, deconstructing the actual profile data reveals more changes that do not appear in the Windows GUI. Here are the low-level changes we discovered, including the ‘Minimum processor state’ previously noted above:
Note: Units differ varying by parameter in this chart - compare within each set of 3 bars.
As you can see, changes were made to help minimize the parking of Ryzen cores, and to also speed up their waking when required. It may not be a perfect solution as it is another step that the user must perform to get good ‘out of the box’ Ryzen performance, but it does help alleviate the dilemma of running your desktop machine at full tilt 24/7 or having to switch power modes on either end of your gaming sessions. This is a solid stop-gap until native Ryzen support makes its way into Windows, so all of you Ryzen users out there, run over to the AMD Blog and grab/install the Ryzen Balanced Power Plan!

Ars Technica asks the question that many reasonable people are also pondering, "Intel still beats Ryzen at games, but how much does it matter?". We here at PCPer have seen the same sorts of responses which Ars has, there is a group of people who had the expectation that Ryzen would miraculously beat any and all Intel chips at every possible task. More experienced heads were hoping for about what we received, a chip which can challenge Broadwell, offering performance which improved greatly on their previous architecture. The launch has revealed some growing pains with AMD's new baby but not anything which makes Ryzen bad.
Indeed, with more DX12 or Vulkan games arriving we should see AMD's performance improve, especially if programmers start to take more effective advantage of high core counts. Head over to read the article, unless you feel that is not a requirement to comment on this topic.
"In spite of this, reading the various reviews around the Web—and comment threads, tweets, and reddit posts—one gets the feeling that many were hoping or expecting Ryzen to somehow beat Intel across the board, and there's a prevailing narrative that Ryzen is in some sense a bad gaming chip. But this argument is often paired with the claim that some kind of non-specific "optimization" is going to salvage the processor's performance, that AMD fans just need to keep the faith for a few months, and that soon Ryzen's full power will be revealed."

Tagged: ryzen, Infinity Fabric, hwbot, FMA3, Control Fabric, bug, amd, AM4
Last week a thread was started at the HWBOT forum and discussed a certain workload that resulted in a hard lock every time it was run. This was tested with a variety of motherboards and Ryzen processors from the 1700 to the 1800X. In no circumstance at default power and clock settings did the processor not lock from the samples that they have worked on, as well as products that contributors have been able to test themselves.
This is quite reminiscent of the Coppermine based Pentium III 1133 MHz processor from Intel which failed in one specific workload (compiling). Intel had shipped a limited number of these CPUs at that time, and it was Kyle from HardOCP and Tom from Tom’s Hardware that were the first to show this behavior in a repeatable environment. Intel stopped shipping these models and had to wait til the Tualatin version of the Pentium III to be released to achieve that speed (and above) and be stable in all workloads.
The interesting thing about this FMA3 finding is that it is seen to not be present in some overclocked Ryzen chips. To me this indicates that it could be a power delivery issue with the chip. A particular workload that heavily leans upon the FPU could require more power than the chip’s Control Fabric can deliver, therefore causing a hard lock. Several tested overclocked chips with much more power being pushed to them seems as though enough power is being applied to the specific area of the chip to allow the operation to be completed successfully.
This particular fact implies to me that AMD does not necessarily have a bug such as what Intel had with the infamous F-Div issue with the original Pentium, or AMD’s issue with the B2 stepping of Phenom. AMD has a very complex voltage control system that is controlled by the Control Fabric portion of the Infinity Fabric. With a potential firmware or microcode update this could be a fixable problem. If this is the case, then AMD would simply increase power being supplied to the FPU/SIMD/SSE portion of the Ryzen cores. This may come at a cost through lower burst speeds to keep TDP within their stated envelope.
A source at AMD has confirmed this issue and that a fix will be provided via motherboard firmware update. More than likely this comes in the form of an updated AGESA protocol.

Amongst the furor of the Ryzen launch the NVIDIA's new Jetson TX2 SoC was quietly sent out to reviewers and today the NDA expired so we can see how it performs. There are more Ryzen reviews below the fold, including Phoronix's Linux testing if you want to skip ahead. In addition to the specifications in the quote, you will find 8GB of 128-bit LPDDR4 offering memory bandwidth of 58.4 GB/s and 32GBs of eMMC for local storage. This Jetson is running JetPack 3.0 L4T based off of the Linux 4.4.15 kernel. Phoronix tested out its performance, see for yourself.
"Last week we got to tell you all about the new NVIDIA Jetson TX2 with its custom-designed 64-bit Denver 2 CPUs, four Cortex-A57 cores, and Pascal graphics with 256 CUDA cores. Today the Jetson TX2 is shipping and the embargo has expired for sharing performance metrics on the JTX2."

AMD's Robert Hallock (previously the Head of Global Technical Marketing for AMD and now working full time on the CPU side of things) has posted a comprehensive Ryzen update, covering AMD's official stance on Windows 10 thread scheduling, the performance implications of SMT, Windows power management settings, and more. The post in its entirety is reproduced below, and also available from AMD by following this link.
It’s been about two weeks since we launched the new AMD Ryzen™ processor, and I’m just thrilled to see all the excitement and chatter surrounding our new chip. Seems like not a day goes by when I’m not being tweeted by someone doing a new build, often for the first time in many years. Reports from media and users have also been good:
- “This CPU gives you something that we needed for a long time, which is a CPU that gives you a well-rounded experience.” –JayzTwoCents
- Competitive performance at 1080p, with Tech Spot saying the “affordable Ryzen 7 1700” is an “awesome option” and a “safer bet long term.”
- ExtremeTech showed strong performance for high-end GPUs like the GeForce GTX 1080 Ti, especially for gamers that understand how much value AMD Ryzen™ brings to the table
- Many users are noting that the 8-core design of AMD Ryzen™ 7 processors enables “noticeably SMOOTHER” performance compared to their old platforms.
While these findings have been great to read, we are just getting started! The AMD Ryzen™ processor and AM4 Platform both have room to grow, and we wanted to take a few minutes to address some of the questions and comments being discussed across the web.
We have investigated reports alleging incorrect thread scheduling on the AMD Ryzen™ processor. Based on our findings, AMD believes that the Windows® 10 thread scheduler is operating properly for “Zen,” and we do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture.
As an extension of this investigation, we have also reviewed topology logs generated by the Sysinternals Coreinfo utility. We have determined that an outdated version of the application was responsible for originating the incorrect topology data that has been widely reported in the media. Coreinfo v3.31 (or later) will produce the correct results.
Finally, we have reviewed the limited available evidence concerning performance deltas between Windows® 7 and Windows® 10 on the AMD Ryzen™ CPU. We do not believe there is an issue with scheduling differences between the two versions of Windows. Any differences in performance can be more likely attributed to software architecture differences between these OSes.
Going forward, our analysis highlights that there are many applications that already make good use of the cores and threads in Ryzen, and there are other applications that can better utilize the topology and capabilities of our new CPU with some targeted optimizations. These opportunities are already being actively worked via the AMD Ryzen™ dev kit program that has sampled 300+ systems worldwide.
Above all, we would like to thank the community for their efforts to understand the Ryzen processor and reporting their findings. The software/hardware relationship is a complex one, with additional layers of nuance when preexisting software is exposed to an all-new architecture. We are already finding many small changes that can improve the Ryzen performance in certain applications, and we are optimistic that these will result in beneficial optimizations for current and future applications.
The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.
Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically.
The table below serves as an example of how the tCTL sensor can be interpreted in a hypothetical scenario where a Ryzen processor is operating at 38°C.
Users may have heard that AMD recommends the High Performance power plan within Windows® 10 for the best performance on Ryzen, and indeed we do. We recommend this plan for two key reasons:
- Core Parking OFF: Idle CPU cores are instantaneously available for thread scheduling. In contrast, the Balanced plan aggressively places idle CPU cores into low power states. This can cause additional latency when un-parking cores to accommodate varying loads.
- Fast frequency change: The AMD Ryzen™ processor can alter its voltage and frequency states in the 1ms intervals natively supported by the “Zen” architecture. In contrast, the Balanced plan may take longer for voltage and frequency (V/f) changes due to software participation in power state changes.
In the near term, we recommend that games and other high-performance applications are complemented by the High Performance plan. By the first week of April, AMD intends to provide an update for AMD Ryzen™ processors that optimizes the power policy parameters of the Balanced plan to favor performance more consistent with the typical usage models of a desktop PC.
Simultaneous Multi-threading (SMT)
Finally, we have investigated reports of instances where SMT is producing reduced performance in a handful of games. Based on our characterization of game workloads, it is our expectation that gaming applications should generally see a neutral/positive benefit from SMT. We see this neutral/positive behavior in a wide range of titles, including: Arma® 3, Battlefield™ 1, Mafia™ III, Watch Dogs™ 2, Sid Meier’s Civilization® VI, For Honor™, Hitman™, Mirror’s Edge™ Catalyst and The Division™. Independent 3rd-party analyses have corroborated these findings.
For the remaining outliers, AMD again sees multiple opportunities within the codebases of specific applications to improve how this software addresses the “Zen” architecture. We have already identified some simple changes that can improve a game’s understanding of the "Zen" core/cache topology, and we intend to provide a status update to the community when they are ready.
Overall, we are thrilled with the outpouring of support we’ve seen from AMD fans new and old. We love seeing your new builds, your benchmarks, your excitement, and your deep dives into the nuts and bolts of Ryzen. You are helping us make Ryzen™ even better by the day. You should expect to hear from us regularly through this blog to answer new questions and give you updates on new improvements in the Ryzen ecosystem.
Such topics as Windows 7 vs. Windows 10 performance, SMT impact, and thread scheduling will no doubt still be debated, and AMD has correctly pointed out that optimization for this brand new architecture will only improve Ryzen performance going forward. Our own findings as to Ryzen and the Windows 10 thread scheduler appear to be validated as AMD officially dismisses performance impact in that area, though there is still room for improvement in other areas from our initial gaming performance findings. As mentioned in the post, AMD will have an update for Windows power plan optimization by the first week of April, and the company has "already identified some simple changes that can improve a game’s understanding of the 'Zen' core/cache topology, and we intend to provide a status update to the community when they are ready", as well.
It is refreshing to see a company publicly acknowledging the topics that have resulted in so much discussion in the past couple of weeks, and their transparency is commendable, with every issue (that this author is aware of) being touched on in the post.

Measuring 50mm x 87mm, the Jetson TX2 packs quite a bit of processing power and I/O including an SoC with two 64-bit Denver 2 cores with 2MB L2, four ARM Cortex A57 cores with 2MB L2, and a 256-core GPU based on NVIDIA’s Pascal architecture. The TX2 compute module also hosts 8 GB of LPDDR4 (58.3 GB/s) and 32 GB of eMMC storage (SDIO and SATA are also supported). As far as I/O, the Jetson TX2 uses a 400-pin connector to connect the compute module to the development board or final product and the final I/O available to users will depend on the product it is used in. The compute module supports up to the following though:
- 2 x DSI
- 2 x DP 1.2 / HDMI 2.0 / eDP 1.4
- USB 3.0
- USB 2.0
- 12 x CSI lanes for up to 6 cameras (2.5 GB/second/lane)
- PCI-E 2.0:
- One x4 + one x1 or two x1 + one x2
- Gigabit Ethernet
The Jetson TX2 runs the “Linux for Tegra” operating system. According to NVIDIA the Jetson TX2 can deliver up to twice the performance of the TX1 or up to twice the efficiency at 7.5 watts at the same performance.
The extra horsepower afforded by the faster CPU, updated GPU, and increased memory and memory bandwidth will reportedly enable smart end user devices with faster facial recognition, more accurate speech recognition, and smarter AI and machine learning tasks (e.g. personal assistant, smart street cameras, smarter home automation, et al). Bringing more power locally to these types of internet of things devices is a good thing as less reliance on the cloud potentially means more privacy (unfortunately there is not as much incentive for companies to make this type of product for the mass market but you could use the TX2 to build your own).
Cisco will reportedly use the Jetson TX2 to add facial and speech recognition to its Cisco Spark devices. In addition to the hardware, NVIDIA offers SDKs and tools as part of JetPack 3.0. The JetPack 3.0 toolkit includes Tensor-RT, cuDNN 5.1, VisionWorks 1.6, CUDA 8, and support and drivers for OpenGL 4.5, OpenGL ES 3 2, EGL 1.4, and Vulkan 1.0.
The TX2 will enable better, stronger, and faster (well I don't know about stronger heh) industrial control systems, robotics, home automation, embedded computers and kiosks, smart signage, security systems, and other connected IoT devices (that are for the love of all processing are hardened and secured so they aren't used as part of a botnet!).
Interested developers and makers can pre-order the Jetson TX2 Development Kit for $599 with a ship date for US and Europe of March 14 and other regions “in the coming weeks.” If you just want the compute module sans development board, it will be available later this quarter for $399 (in quantities of 1,000 or more). The previous generation Jetson TX1 Development Kit has also received a slight price cut to $499.

Tagged: softbank, investments, business, arm
Japanese telecom powerhouse SoftBank, which recently purchased ARM Holdings for $32 billion USD is reportedly in talks to sell off a 25% stake in its new subsidiary to a new investment fund. Specifically, the New York Times cites a source inside SoftBank familiar with the matter who revealed that SoftBank is in talks with the Vision Fund to purchase a stake in ARM Holdings worth approximately $8 billion USD.
The $100 billion Vision Fund is an investment fund started by SoftBank founder Masayoshi Son with a goal of investing in high growth technology start-ups and major technology IP holders. The fund is currently comprised of investments from SoftBank worth $25 billion, $45 billion from Saudi Arabia (via Saudi Arabia Public Investment Fund), and minor investments from Apple and Oracle co-founder Lawrence Ellison. The fund is approximately 75% of the way to its $100 billion funding goal with the state owned Mubadala Development investment company in Abu Dhabi and the Qatari government allegedly interested in joining the fund. The Vision Fund is based in the UK and led by SoftBank's Head of Strategic Finance Rajeev Mistra (Investment bankers Nizar al-Bassam and Dalin Ariburnu formerly of Deutsche Bank and Goldman Sachs respectively are also involved.)
It is interesting that SoftBank plans to sell off such a large stake in ARM Holdings so soon after purchasing the company (the sale finalized only six months ago), but it may be a move to entice investors to the investment fund which SoftBank is a part of to further diversify its assets. The more interesting question is the political and regulatory reaction to this news and what it will mean for ARM and its IP to have even more countries controlling it and its direction(s). I do not have the geopolitical acumen to speculate on whether this is a good or bad thing (heh). It does continue the trend of countries outside of the US increasing their investments in established technology companies with lots of IP (wether US based or not) as well as new start ups. New money entering this sector is likely overall good though, at least for the companies involved heh.
I guess we will just have to wait and see if the sale completes and where ARM goes from there! What are your thoughts on the SoftBank sale of a quarter stake in ARM?
