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.
Drop by to take a look and don't forget there are a whole lot more just below.
"AMD has been on a tear with its new Ryzen 7 CPUs over the past few weeks and now it is time for the Ryzen 5 processor family performance to be explored. We are giving away the AMD Reviewer's Kit with a 1600X and 1500X, instead we bought 1600 and 1400 processors to review here today. All data is retail CPUs, and all overclocked to 4GHz."

The real battle begins
When AMD launched the Ryzen 7 processors last month to a substantial amount of fanfare and pent up excitement, we already knew that the Ryzen 5 launch would be following close behind. While the Ryzen 7 lineup was meant to compete with the Intel Core i7 Kaby Lake and Broadwell-E products, with varying levels of success, the Ryzen 5 parts are priced to go head to head with Intel's Core i5 product line.
AMD already told us the details of the new product line including clock speeds, core counts and pricing, so there is little more to talk about other than the performance and capabilities we found from our testing of the new Ryzen 5 parts. Starting with the Ryzen 5 1600X, with 6 cores, 12 threads and a $249 price point, and going down to the Ryzen 5 1400 with 4 cores, 8 threads and a $169 price point, this is easily AMD's most aggressive move to date. The Ryzen 7 1800X at $499 was meant to choke off purchases of Intel's $1000+ parts; Ryzen 5 is attempting to offer significant value and advantage for users on a budget.
Today we have the Ryzen 5 1600X and Ryzen 5 1500X in our hands. The 1600X is a 6C/12T processor that will have a 50% core count advantage over the Core i5-7600K it is priced against but a 3x advantage in thread count because of Intel's disabling of HyperThreading on Core i5 desktop processors. The Ryzen 5 1500X has the same number of cores as the Core i5-7500 it will be pitted against, but 2x the thread count.
How does this fare for AMD? Will budget consumers finally find a solution from the company that has no caveats?

Perhaps it is best not to ask how this came about, but you can order the Ryzen 5 1600 and 1400 from eBay. The seller has an impressive reputation and as Kyle over at [H]ard|OCP has already ordered and received some, this should be a fairly safe opportunity to take advantage of. The full review has not yet been published but that did not stop them from putting together a quick overclocking video. If you have 20 minutes to spare and an interest in AMD's new processors you should take a look.
"Much to our surprise, AMD Ryzen 5 CPUs started showing up online for sale last week in North America, so we did what any PC hardware review site would do. We went out and bought four of those and started working on seeing just how much overclocking headroom each of these new CPUs have."

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!
Tweaks for days
It seems like it’s been months since AMD launched Ryzen, its first new processor architecture in about a decade, when in fact we are only four weeks removed. One of the few concerns about the Ryzen processors centered on its performance in some gaming performance results, particularly in common resolutions like 1080p. While I was far from the only person to notice these concerns, our gaming tests clearly showed a gap between the Ryzen 7 1800X and the Intel Core i7-7700K and 6900K processors in Civilization 6, Hitman and Rise of the Tomb Raider.
A graph from our Ryzen launch coverage...
We had been working with AMD for a couple of weeks on the Ryzen launch and fed back our results with questions in the week before launch. On March 2nd, AMD’s CVP of Marketing John Taylor gave us a prepared statement that acknowledged the issue but promised changes come in form for game engine updates. These software updates would need to be implemented by the game developers themselves in order to take advantage of the unique and more complex core designs of the Zen architecture. We had quotes from the developers of Ashes of the Singularity as well as the Total War series to back it up.
And while statements promising change are nice, it really takes some proof to get the often skeptical tech media and tech enthusiasts to believe that change can actually happen. Today AMD is showing its first result.
The result of 400 developer hours of work, the Nitrous Engine powering Ashes of the Singularity received an update today to version 26118 that integrates updates to threading to better balance the performance across Ryzen 7’s 8 cores and 16 threads. I was able to do some early testing on the new revision, as well as with the previous retail shipping version (25624) to see what kind of improvements the patch brings with it.
Stardock / Oxide CEO Brad Wardell had this to say in a press release:
“I’ve always been vocal about taking advantage of every ounce of performance the PC has to offer. That’s why I’m a strong proponent of DirectX 12 and Vulkan® because of the way these APIs allow us to access multiple CPU cores, and that’s why the AMD Ryzen processor has so much potential,” said Stardock and Oxide CEO Brad Wardell. “As good as AMD Ryzen is right now – and it’s remarkably fast – we’ve already seen that we can tweak games like Ashes of the Singularity to take even more advantage of its impressive core count and processing power. AMD Ryzen brings resources to the table that will change what people will come to expect from a PC gaming experience.”
Our testing setup is in line with our previous CPU performance stories.
|Test System Setup|
|CPU||AMD Ryzen 7 1800X
Intel Core i7-6900K
|Motherboard||ASUS Crosshair VI Hero (Ryzen)
ASUS X99-Deluxe II (Broadwell-E)
|Storage||Corsair Force GS 240 SSD|
|Graphics Card||NVIDIA GeForce GTX 1080 8GB|
|Graphics Drivers||NVIDIA 378.49|
|Power Supply||Corsair HX1000|
|Operating System||Windows 10 Pro x64|
I was using the latest BIOS for our ASUS Crosshair VI Hero motherboard (1002) and upgraded to some Geil RGB (!!) memory capable of running at 3200 MHz on this board with a single BIOS setting adjustment. All of my tests were done at 1080p in order to return to the pain point that AMD was dealing with on launch day.
Let’s see the results.
These are substantial performance improvements with the new engine code! At both 2400 MHz and 3200 MHz memory speeds, and at both High and Extreme presets in the game (all running in DX12 for what that’s worth), the gaming performance on the GPU-centric is improved. At the High preset (which is the setting that AMD used in its performance data for the press release), we see a 31% jump in performance when running at the higher memory speed and a 22% improvement with the lower speed memory. Even when running at the more GPU-bottlenecked state of the Extreme preset, that performance improvement for the Ryzen processors with the latest Ashes patch is 17-20%!
It’s also important to note that Intel performance is unaffected – either for the better or worse. Whatever work Oxide did to improve the engine for AMD’s Ryzen processors had NO impact on the Core processors, which is interesting to say the least. The cynic in me would believe there is little chance that any agnostic changes to code would raise Intel’s multi-core performance at least a little bit.
So what exactly is happening to the engine with v26118? I haven’t had a chance to have an in-depth conversation with anyone at AMD or Oxide yet on the subject, but at a high level, I was told that this is what happens when instructions and sequences are analyzed for an architecture specifically. “For basically 5 years”, I was told, Oxide and other developers have dedicated their time to “instruction traces and analysis to maximize Intel performance” which helps to eliminate poor instruction setup. After spending some time with Ryzen and the necessary debug tools (and some AMD engineers), they were able to improve performance on Ryzen without adversely affecting Intel parts.
Core to core latency testing on Ryzen 7 1800X
I am hoping to get more specific detail in the coming days, but it would seem very likely that Oxide was able to properly handle the more complex core to core communication systems on Ryzen and its CCX implementation. We demonstrated early this month how thread to thread communication across core complexes causes substantially latency penalties, and that a developer that intelligently manages threads that have dependencies on the core complex can improve overall performance. I would expect this is at least part of the solution Oxide was able to integrate (and would also explain why Intel parts are unaffected).

- Ryzen 7 1700X - $399 - Amazon.com
- Ryzen 7 1700 - $329 - Amazon.com
What is important now is that AMD takes this momentum with Ashes of the Singularity and actually does something with it. Many of you will recognize Ashes as the flagship title for Mantle when AMD made that move to change the programming habits and models for developers, and though Mantle would eventually become Vulkan and drive DX12 development, it did not foretell an overall shift as it hoped to. Can AMD and its developer relations team continue to make the case that spending time and money (which is what 400 developer hours equates to) to make specific performance enhancements for Ryzen processors is in the best interest of everyone? We’ll soon find out.

A new start
Qualcomm is finally ready to show the world how the Snapdragon 835 Mobile Platform performs. After months of teases and previews, including a the reveal that it was the first processor built on Samsung’s 10nm process technology and a mostly in-depth look at the architectural changes to the CPU and GPU portions of the SoC, the company let a handful of media get some hands-on time with development reference platform and run some numbers.
To frame the discussion as best I can, I am going to include some sections from my technology overview. This should give some idea of what to expect from Snapdragon 835 and what areas Qualcomm sees providing the widest variation from previous SD 820/821 product.
Qualcomm frames the story around the Snapdragon 835 processor with what they call the “five pillars” – five different aspects of mobile processor design that they have addressed with updates and technologies. Qualcomm lists them as battery life (efficiency), immersion (performance), capture, connectivity, and security.
Starting where they start, on battery life and efficiency, the SD 835 has a unique focus that might surprise many. Rather than talking up the improvements in performance of the new processor cores, or the power of the new Adreno GPU, Qualcomm is firmly planted on looking at Snapdragon through the lens of battery life. Snapdragon 835 uses half of the power of Snapdragon 801.
Since we already knew that the Snapdragon 835 was going to be built on the 10nm process from Samsung, the first such high performance part to do so, I was surprised to learn that Qualcomm doesn’t attribute much of the power efficiency improvements to the move from 14nm to 10nm. It makes sense – most in the industry see this transition as modest in comparison to what we’ll see at 7nm. Unlike the move from 28nm to 14/16nm for discrete GPUs, where the process technology was a huge reason for the dramatic power drop we saw, the Snapdragon 835 changes come from a combination of advancements in the power management system and offloading of work from the primary CPU cores to other processors like the GPU and DSP. The more a workload takes advantage of heterogeneous computing systems, the more it benefits from Qualcomm technology as opposed to process technology.

Tagged: amd, Intel, ryzen, sanity check
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."

Here Comes the Midrange!
Today AMD is announcing the upcoming Ryzen 5 CPUs. A little bit was known about them from several weeks ago when AMD talked about their upcoming 6 core processors, but official specifications were lacking. Today we get to see what Ryzen 5 is mostly about.
There are four initial SKUs that AMD is talking about this evening. These encompass quad core and six core products. There are two “enthusiast” level SKUs with the X connotation while the other two are aimed at a less edgy crowd.
The two six core CPUs are the 1600 and 1600X. The X version features the higher extended frequency range when combined with performance cooling. That unit is clocked at a base 3.6 GHz and achieves a boost of 4 GHz. This compares well to the top end R7 1800X, but it is short 2 cores and four threads. The price of the R5 1600X is a very reasonable $249. The 1600 does not feature the extended range, but it does come in at a 3.2 GHz base and 3.6 GHz boost. The R5 1600 has a MSRP of $219.
When we get to the four core, eight thread units we see much the same stratification. The top end 1500X comes in at $189 and features a base clock of 3.5 GHz and a boost of 3.7 GHz. What is interesting about this model is that the XFR is raised by 100 MHz vs. other XFR CPUs. So instead of an extra 100 MHz boost when high end cooling is present we can expect to see 200 MHz. In theory this could run at 3.9 GHz in the extended state. The lowest priced R5 is the 1400 which comes in at a very modest $169. This features a 3.2 GHz base clock and a 3.4 GHz boost.
The 1400, 1500, and 1600 CPUs come with Wraith cooling solutions. The 1600X comes bare as it is assumed that users want to use something a bit more robust. The R5 1400 comes with the lower end Wraith Stealth cooler while the R5 1500X and R5 1600 come with the bigger Wraith Spire. The bottom 3 SKUs are all rated at 65 watts TDP. The 1600X comes in at the higher 95 watt rating. Each of the CPUs are unlocked for overclocking.
These chips will provide a more fleshed out pricing structure for the Ryzen processors and provide users and enthusiasts with lower cost options for those wanting to invest in AMD again. These chips all run on the new AM4 platform which are pretty strong in terms of features and I/O performance.
AMD is not shipping these parts today, but rather announcing them. Review samples are not in hand yet and AMD expects world-wide availability by April 11. This is likely a very necessary step for AMD as current AM4 motherboard availability is not at the level we were expecting to see. We also are seeing some pretty quick firmware updates from motherboard partners to address issues with these first AM4 boards. By April 11 I would expect to see most of the issues solved and a healthy supply of motherboards on the shelves to handle the influx of consumers waiting to buy these more midrange priced CPUs from AMD.
What they did not cover or answer would be how the four core products would be presented. Would each be a single CCX and only 8 MB of L3 cace, or would AMD disable two cores in each CCX and present 16 MB of L3? We currently do not have the answer to this. Considering the latency between accessing different CCX units we can surely hope they only keep one CCX active.
Ryzen has certainly been a success for AMD and I have no doubt that their quarter will be pretty healthy with the estimated sales of around 1 million Ryzen CPUs since launch. Announcing these new chips will give the mainstream and budget enthusiasts something to look forward to and plan their purchases around. AMD is not announcing the Ryzen 3 products at this time.
Update: AMD got back to me this morning about a question I asked them about the makeup of cores, CCX units, and L3 cache. Here is their response.
1600X: 3+3 with 16MB L3 cache. 1600: 3+3 with 16MB L3 cache. 1500X: 2+2 with 16MB L3 cache. 1400: 2+2 with 8MB L3 cache. As with Ryzen 7, each core still has 512KB local L2 cache.
