The design of the Gigabyte GA-AB350-Gaming 3 is quite spartan, but don't let that fool you as it is heavily infected with RGB-itis.  This brand new AMD motherboard is a hair thinner than your average ATX motherboard, at 305x230mm but that doesn't mean the board is lacking in features.  There is a single x16 PCIe 3.0 slot, and a sole x4 PCIe 2.0 slot with three  x1 PCIe 2.0 slots for additional cards.  Of the six SATA ports, only four can be used if you install an M.2 SSD, a reasonable pool of drives for most.  There is HDMI 1.4 and DVI connectors on the back, along with a half dozen USB 3.1 ports on the back of which two are Gen 2 and four Gen 1.  Check out the full review at Modders Inc.

A reasonable response about Ryzen, please do not check your sanity at the door

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."

Microsoft is making friends again, no new Win 7/8 updates for new chips

Subject: General Tech | March 17, 2017 - 01:11 PM |

KB4012982 describes the error you will see if you attempt to update Windows 7 or 8.x on 7th generation Intel processors, AMD Bristol Ridge and newer or Qualcomm "8996" and more recent models.  Microsoft has implemented the hardware based obsolescence which they had discussed several months ago when they stated that new chips would need Windows 10 to run.  This move will of course be heralded as brilliant and no one could possibly find this upsetting in the least, especially not in this Reddit thread.  It is a good thing Microsoft does not have a near monopoly in the market and that anyone who does not support this decision can choose from a wide variety of easily implemented alternatives.

Expect there to be workarounds, the vast majority of Enterprise customers have no interest in moving their infrastructure to Windows 10, nor the budget available to do so if they wanted.

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.

ryzen5_01.png

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.

ryzen5_04.png

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.

ryzen5_02.png

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.

ryzen5_05.png

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.

Ryzen Locking on Certain FMA3 Workloads

Subject: Processors | March 15, 2017 - 05:51 PM |
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.

ryzen.jpg

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.

AMD Ryzen Community Update Addresses Windows 10 Thread Scheduling, SMT Performance, and More

Subject: Processors | March 13, 2017 - 08:48 PM |
Tagged: Windows 7, windows 10, thread scheduling, SMT, ryzen, Robert Hallock, processor, cpu, amd

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.

AMD_RYZEN.png

(Begin statement:)

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.

Thread Scheduling

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.

Temperature Reporting

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.

TEMPS.png

Power Plans

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: 

  1. 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.
  2. 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.

Wrap-up

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.

(End statement.)

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.

** UPDATE 3/13 5 PM **

AMD has posted a follow-up statement that officially clears up much of the conjecture this article was attempting to clarify. Relevant points from their post that relate to this article as well as many of the requests for additional testing we have seen since its posting (emphasis mine):

  • "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."

  • "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."

So there you have it, straight from the horse's mouth. AMD does not believe the problem lies within the Windows thread scheduler. SMT performance in gaming workloads was also addressed:

  • "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."

We are still digging into the observed differences of toggling SMT compared with disabling the second CCX, but it is good to see AMD issue a clarifying statement here for all of those out there observing and reporting on SMT-related performance deltas.

** END UPDATE **

Editor's Note: The testing you see here was a response to many days of comments and questions to our team on how and why AMD Ryzen processors are seeing performance gaps in 1080p gaming (and other scenarios) in comparison to Intel Core processors. Several outlets have posted that the culprit is the Windows 10 scheduler and its inability to properly allocate work across the logical vs. physical cores of the Zen architecture. As it turns out, we can prove that isn't the case at all. -Ryan Shrout

Initial reviews of AMD’s Ryzen CPU revealed a few inefficiencies in some situations particularly in gaming workloads running at the more common resolutions like 1080p, where the CPU comprises more of a bottleneck when coupled with modern GPUs. Lots of folks have theorized about what could possibly be causing these issues, and most recent attention appears to have been directed at the Windows 10 scheduler and its supposed inability to properly place threads on the Ryzen cores for the most efficient processing. 

I typically have Task Manager open while running storage tests (they are boring to watch otherwise), and I naturally had it open during Ryzen platform storage testing. I’m accustomed to how the IO workers are distributed across reported threads, and in the case of SMT capable CPUs, distributed across cores. There is a clear difference when viewing our custom storage workloads with SMT on vs. off, and it was dead obvious to me that core loading was working as expected while I was testing Ryzen. I went back and pulled the actual thread/core loading data from my testing results to confirm:

SMT on usage.png

The Windows scheduler has a habit of bouncing processes across available processor threads. This naturally happens as other processes share time with a particular core, with the heavier process not necessarily switching back to the same core. As you can see above, the single IO handler thread was spread across the first four cores during its run, but the Windows scheduler was always hitting just one of the two available SMT threads on any single core at one time.

My testing for Ryan’s Ryzen review consisted of only single threaded workloads, but we can make things a bit clearer by loading down half of the CPU while toggling SMT off. We do this by increasing the worker count (4) to be half of the available threads on the Ryzen processor, which is 8 with SMT disabled in the motherboard BIOS.

smtoff4workers.png

SMT OFF, 8 cores, 4 workers

With SMT off, the scheduler is clearly not giving priority to any particular core and the work is spread throughout the physical cores in a fairly even fashion.

Now let’s try with SMT turned back on and doubling the number of IO workers to 8 to keep the CPU half loaded:

smton8workers.png

SMT ON, 16 (logical) cores, 8 workers

With SMT on, we see a very different result. The scheduler is clearly loading only one thread per core. This could only be possible if Windows was aware of the 2-way SMT (two threads per core) configuration of the Ryzen processor. Do note that sometimes the workload will toggle around every few seconds, but the total loading on each physical core will still remain at ~%50. I chose a workload that saturated its thread just enough for Windows to not shift it around as it ran, making the above result even clearer.

Synthetic Testing Procedure

While the storage testing methods above provide a real-world example of the Windows 10 scheduler working as expected, we do have another workload that can help demonstrate core balancing with Intel Core and AMD Ryzen processors. A quick and simple custom-built C++ application can be used to generate generic worker threads and monitor for core collisions and resolutions.

This test app has a very straight forward workflow. Every few seconds it generates a new thread, capping at N/2 threads total, where N is equal to the reported number of logical cores. If the OS scheduler is working as expected, it should load 8 threads across 8 physical cores, though the division between the specific logical core per physical core will be based on very minute parameters and conditions going on in the OS background.

By monitoring the APIC_ID through the CPUID instruction, the first application thread monitors all threads and detects and reports on collisions - when a thread from our app is running on the same core as another thread from our app. That thread also reports when those collisions have been cleared. In an ideal and expected environment where Windows 10 knows the boundaries of physical and logical cores, you should never see more than one thread of a core loaded at the same time.

app01.png

Click to Enlarge

This screenshot shows our app working on the left and the Windows Task Manager on the right with logical cores labeled. While it may look like all logical cores are being utilized at the same time, in fact they are not. At any given point, only LCore 0 or LCore 1 are actively processing a thread. Need proof? Check out the modified view of the task manager where I copy the graph of LCore 1/5/9/13 over the graph of LCore 0/4/8/12 with inverted colors to aid viewability.

app02-2.png

If you look closely, by overlapping the graphs in this way, you can see that the threads migrate from LCore 0 to LCore 1, LCore 4 to LCore 5, and so on. The graphs intersect and fill in to consume ~100% of the physical core. This pattern is repeated for the other 8 logical cores on the right two columns as well. 

Running the same application on a Core i7-5960X Haswell-E 8-core processor shows a very similar behavior.

app03.png

Click to Enlarge

Each pair of logical cores shares a single thread and when thread transitions occur away from LCore N, they migrate perfectly to LCore N+1. It does appear that in this scenario the Intel system is showing a more stable threaded distribution than the Ryzen system. While that may in fact incur some performance advantage for the 5960X configuration, the penalty for intra-core thread migration is expected to be very minute.

The fact that Windows 10 is balancing the 8 thread load specifically between matching logical core pairs indicates that the operating system is perfectly aware of the processor topology and is selecting distinct cores first to complete the work.

Information from this custom application, along with the storage performance tool example above, clearly show that Windows 10 is attempting to balance work on Ryzen between cores in the same manner that we have experienced with Intel and its HyperThreaded processors for many years.

There are now two less working Ryzen 1700 processors on the planet, sacrificed in an experiment to delid the new AMD products.  The third lived and was tested by der8auer, the mad experimenter, to see what benefits cooling the die directly provide.  The answer is a 2C drop.  This does not seem worth it, considering the high risk, an opinion that Guru 3D shares.  You can of course proceed to do so if you wish, but you might want to buy a half dozen processors to save yourself some time.

"We mentioned in our reviews that you should not delid AMD Ryzen processors for the sheer fact that even the heatspreader has sensors and that it is soldered. Next to that AMD did the cooling part rather well so the benefits of a lower temperatures versus the risk of bricking that processor might not be worth it."
