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!

AMD Releases Radeon Software Crimson ReLive 17.4.1

Subject: Graphics Cards | April 4, 2017 - 09:21 PM |
Tagged: graphics drivers, amd

The first AMD Radeon driver of April isn’t aligned with a major game launch. Instead, this release seems to focus on gaming technologies in general. For VR, Radeon Software Crimson ReLive 17.4.1 adds Oculus’ Asynchronous Spacewarp (ASW) to R9 Fury, R9 390, and R9 290 graphics cards. It also adds, for Windows 10, SteamVR Asynchronous Reprojection to RX 480 and RX 470 graphics cards.

The driver also adds a couple of extra display options based on the (also just added) DP1.4 HBR3 cable standard. For now, it seems like it’s just (read: “just”) 8K 60 Hz dual-cable and 8K 30Hz single-cable. The increased bandwidth also allows for several other formats, but those have nothing to do with today’s driver.

Update: AMD released a video on the same day to advertise 8K / HDR / FreeSync 2. Embed below.

A few bugs were also fixed, most of which were general bug-fixes not associated with games. Tom Clancy’s Ghost Recon Wildlands is the one exception, which should now scale better with multiple GPUs.

AMD Radeon Software Crimson ReLive 17.4.1 is now available from AMD’s website.

ASRock's X370 Taichi, meet AMD's new chipset

Subject: Motherboards | April 4, 2017 - 01:47 PM |
Tagged: x370, asrock, X370 Taichi, amd, AM4

Morry just wrapped up a review of the ASUS Strix Z270E Gaming while Hardware Canucks have looked at a different motherboard, the ASRock X370 Taichi.  To some, the names might seem similar but they are very different motherboards, the Z270 is for Intel LGA1151 while the X370 is a brand new AMD AM4 board.  If you are just getting into building computers, make very sure you know what you are picking up!

ASRock have chosen a unique pattern to decorate the X370 Taichi and that is before you light up the RGB LEDs on the board.  This is the first AM4 board Hardware Canucks have seen and it introduces a new look to the UEFI as well as some physical changes to the layout compared to the previous generation of AMD motherboards.  Take look for yourself at one of the first reviews of an AM4 board from ASRock.

Ryzen from the Ashes in a new optimized state

Tagged: amd, ryzen, ashes of the singularity

[H]ard|OCP takes a look at the new optimizations in the Oxide Game Engine and come up with similar positive results as Ryan.  They tested the CPU by dropping the resolution and quality in AotS and utilizing the CPU focused benchmark, as opposed to the GPU focused benchmark utilized by many sites, including ourselves.  Their tests showed a 16.46% improvement which shows these optimizations do not simply have an effect on graphical performance but also improve CPU calculation performance as well.  Pop by for the full review.

"There has been a lot of talk about how AMD's new Ryzen processors have pulled up somewhat short at low resolution gaming. AMD explained that code optimizations from game developers are needed to address this issue, and today is the day that we are supposed to start seeing some of that code in action."

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)
Memory 16GB DDR4-2400
Storage Corsair Force GS 240 SSD
Sound Card On-board
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%!

DSC02636.jpg

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).

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.

Teasing a little information out of AMD about Vega

Subject: General Tech | March 28, 2017 - 01:04 PM |
Tagged: amd, Vega, rumour, HBM2

The Inquirer have posted a tiny bit of information about AMD's upcoming Vega and as any rumours about the new GPU are hard to find it is the best we have at the moment.  AMD's claim is that the second generation HBM present on the 4GB and 8GB models could offer equivalent memory bandwidth to a GTX 1080 Ti, which makes perfect sense.  The GTX 1080 Ti offers 484 GB/s of memory bandwidth while AMD's R9 series first generation HBM offers 512 GB/s.  The real trick is filling that pipeline to give AMD's HBM2 based cards a chance to shine and which depends on software developers as much as it does the hardware.  As well, The Inquirer discusses the possible efficiency advantages that Vega will have, which could result in smaller cards as well as an effective mobile product.  Pop over to take a look at the current rumours, here is hoping we can provide more detailed information in the near future.

The clean cut Gigabyte GA-AB350-Gaming 3

Tagged: gigabyte, AB350-Gaming 3, b350, amd, ryzen

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.

"AMD is back with a new CPU line-up that brings competitive performance once again against Intel’s current generation of processors at a lower price. In true AMD fashion, the AM4 motherboard line offers the same value alternative as well, offering the latest features similarly found on the latest generation Intel processors natively including USB 3.1 Gen 2, M.2 NVMe support …"

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

Subject: Processors | March 17, 2017 - 03:48 PM |
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."
