Last week a new update was pushed out to Deus Ex: Mankind Divided that made DX12 a part of the main line build and also integrated early support for multi-GPU support under DX12. I wanted to quickly see what kind of scaling it provided as we still have very few proof points on the benefit of running more than one graphics card with games utilizing the DX12 API.

As it turns out, the current build and driver combination only shows scaling on the AMD side of things. NVIDIA still doesn't have DX12 multi-GPU support enabled at this point for this title.

  • Test System
  • Core i7-5960X
  • X99 MB + 16GB DDR4
  • AMD Radeon RX 480 8GB
    • Driver: 16.10.2
  • NVIDIA GeForce GTX 1060 6GB
    • Driver: 375.63

Not only do we see great scaling in terms of average frame rates, but using PresentMon for frame time measurment we also see that the frame pacing is consistent and provides the user with a smooth gaming experience.

AMD Releases Radeon Software Crimson Edition 16.10.3

If you are experiencing crashes in Titanfall 2, and you are using an AMD graphics card, then you will probably be interested in AMD's Radeon Software Crimson Edition 16.10.3. According to its release notes, that is the only issue this hotfix driver addresses.

Also, being a hotfix driver, you might have issues with clean installs of Windows 10 Anniversary Update, because I'm not sure if it's signed by Microsoft. It might be, but that's obviously a fairly narrow subset of hardware and software that I cannot test on a single machine. If that's the case, though, then you can temporarily disable Secure Boot... or just wait until AMD releases a signed driver.

I should note that, while we're posting this a couple of days late, like our news about NVIDIA's driver, AMD was able to release this the day before Titanfall 2 launched. Our readers, at least I hope, found out about the update before now, rather than suffering through some crashes when a fix was already available. Sorry that I didn't get a post up sooner, though; AMD did their part.

Something awful happened and you can no longer wait for Zen to arrive; you need a low cost motherboard and chip ASAP.  Your memory, storage and PSU are all good, you just need something to plug them into and you really don't want to spend a lot upgrading with new silicon just around the corner.  Alternatively, perhaps you have some components lying around and need a system capable of basic tasks and again, you don't want to spend a lot to get it up and running. 

The BioStar A68N-5200 eTeknix just tested might just be what you need, up to 16GB DDR3, a single PCIe 16x slot, a pair of SATA 6.0Gb/s slots, two USB 3.0 slots and four USB 2.0 along with other connectors and an quad-core A6-5200 with HD8400 graphics onboard.  You won't win any benchmarking contests but it is a decent start for $60.

"Despite a lot of the media focus being on Kaby Lake and AMD’s fabled Zen architecture, it’s important to remember that some users require a new motherboard as a matter of urgency and cannot wait for upcoming solutions. Not only that, in low-end scenarios such as a home office system or HTPC, modern processors provide more than enough performance."

DigitalFoundry Compares GTX 1060 & RX 480 in Battlefield 1

Subject: Graphics Cards | October 20, 2016 - 12:08 AM |
Tagged: amd, nvidia, gtx 1060, rx 480, dx12, dx11, battlefield 1

Battlefield 1 is just a few days from launching. In fact, owners of the Deluxe Edition have the game unlock yesterday. It's interesting that multiple publishers are using release date as a special edition bonus these days, including Microsoft's recent Windows Store releases. I'm not going to say interesting bad or good, though, because I'll leave that up to the reader to decide.

Anywho, DigitalFoundry is doing their benchmarking thing, and they wanted to see what GPU could provide a solid 60FPS when everything is maxed out (at 1080p). They start off with a DX12-to-DX12 comparison between the GTX 1060 and the RX 480. This is a relatively fair comparison, because the 3GB GTX 1060 and the 4GB RX 480 both come in at about $200, while upgrading to 6GB for the 1060 or 8GB for the 480 bumps each respective SKU up to the ~$250 price point. In this test, NVIDIA has a few dips slightly below 60 FPS in complex scenes, while AMD stays above that beloved threshold.

They also compare the two cards in DX11 and DX12 mode, with both cards using a Skylake-based Core i5 CPU. In this test, AMD's card noticed a nice increase in frame rate when switching to DirectX 12, while NVIDIA had a performance regression in the new API. This raises two questions, one of which is potentially pro-NVIDIA, and the other, pro-AMD. First, would the original test, if NVIDIA's card was allowed to use DirectX 11, show the GTX 1060 more competitive against the DX12-running RX 480? This brings me to the second question: what would the user see? A major draw of Mantle-based graphics APIs is that the application has more control over traditionally driver-level tasks. Would 60 FPS in DX12 be more smooth than 60 FPS in DX11?

I don't know. It's something we'll need to test.

Expect to hear news from AMD's VR boffins

AMD's Polaris cards have been lagging behind NVIDIA's Pascal in VR performance, not completely surprising considering the deltas in price and 3D performance.  From DigiTimes we hear of some successes however; AMD is opening VR facilities in shopping malls, movie theatres and Internet cafes, currently focusing on China.  On might consider the price as being a major factor, AMD offers good enough performance for most at a price lower than the competition.  They are also focusing on the development side of the equation, discussing their Radeon Pro WX 7100 a solution for a number of providers.  Their Loom project should also see light towards the end of the year, bringing HD content and beyond to VR movie designers.  It will be interesting to see how AMD does against the competition on the design side of the market as opposed to consumer machines.

"AMD has launched several new projects for its virtual reality (VR) business including GPU certification. It has enhanced its software/hardware platform and established a VR supply chain, hoping to expand its presence in the VR market, and to regain share in the graphics card market with its new Polaris GPUs."

AMD Discusses Multi-GPU Frame Pacing in DirectX 12

Subject: Graphics Cards | October 6, 2016 - 01:01 AM |
Tagged: amd, frame pacing, DirectX 12

When I first read this post, it was on the same day that AMD released their Radeon Software Crimson Edition 16.10.1 drivers, although it was apparently posted the day prior. As a result, I thought that their reference to 16.9.1 was a typo, but it apparently wasn't. These changes have been in the driver for a month, at least internally, but it's unclear how much it was enabled until today. (The Scott Wasson video suggests 16.10.1.) It would have been nice to see it on their release notes as a new feature, but at least they made up for it with a blog post and a video.

If you don't recognize him, Scott Wasson used to run The Tech Report, and he shared notes with Ryan while we were developing our Frame Rating testing methodology. He was focused on benchmarking GPUs by frame time, rather than frame rate, because the number of frames that the user sees means less than how smooth the animation they present is. Our sites diverged on implementation, though, as The Tech Report focused on software, while Ryan determined that capturing and analyzing output frames, intercepted between the GPU and the monitor, would tell a more complete story. Regardless, Scott Wasson left his site to work for AMD last year, with the intent to lead User Experience.

We're now seeing AMD announce frame pacing for DirectX 12 Multi-GPU.

This feature particularly interesting, because, depending on the multi-adapter mode, a lot of that control should be in the hands of the game developers. It seems like the three titles they announced, 3D Mark: Time Spy, Rise of the Tomb Raider, and Total War: Warhammer, would be using implicit linked multi-adapter, which basically maps to CrossFire. I'd be interested to see if they can affect this in explicit mode via driver updates as well, but we'll need to wait and see for that (and there isn't many explicit mode titles anyway -- basically just Ashes of the Singularity for now).

If you're interested to see how multi-GPU load-balancing works, we published an animation a little over a month ago that explains three different algorithms, and how explicit APIs differ from OpenGL and DirectX 11. It is also embedded above.

AMD Releases Radeon Software Crimson Edition 16.10.1

Subject: Graphics Cards | October 6, 2016 - 12:37 AM |
Tagged: graphics drivers, amd

Earlier today, AMD has released their Radeon Software Crimson Edition 16.10.1 drivers. These continue AMD's trend of releasing drivers alongside major titles, which, this time, are Mafia III (October 7th) and Gears of War 4 (October 11th). Both of these titles are multiple days out, apart from a handful of insiders with advanced copies, which makes it nice for gamers by letting them optimize their machine ahead of time, on their own schedule, before launch.

The driver also includes a handful of interesting fixes. First, a handful of games, such as Overwatch, Battlefield 1, and Paragon, should no longer flicker when set to CrossFire mode. Also, performance issues in The Crew should be fixed with this release.

You can download AMD Radeon Software Crimson Edition 16.10.1 from their website.

Mid-Range Gigabyte Socket AM4 (B350 Chipset) Micro ATX Motherboard Pictured

Subject: Motherboards | October 2, 2016 - 03:20 AM |
Tagged: Zen, micro ATX, Excavator, Bristol Ridge, b350, amd, AM4

Thanks to a recent leak over at Bodnara.co.kr (which has since been taken down), pictures emerged online that give a first look at an AMD socket AM4 motherboard using the mid-range B350 chipset. The Gigabyte B350M-DS3H is a Micro ATX motherboard supporting Bristol Ridge processors at launch and Zen-based processors next year.

The mid-range AM4 board has a very simple layout that leaves little mystery. There are no large heatsinks and no northbridge thanks to AMD moving most of the connectivity to the SoC itself. In fact there is only a small passively cooled chip in the bottom right corner (the B350 chipset) that between the SoC and it can offer up PCI-E 3.0, SATA 6.0, USB 3.1, USB 3.0, NVMe SSD, and DDR4 memory support. This post outlines how the duties are split between the processor and southbridge.

Gigabyte AMD AMD4 B350 Chipset Motherboard.jpg

The B350M-DS3H is powered by a 24-pin ATX and 8-pin EPS and Gigabyte is using a seven phase VRM to power the processor and memory. The board hosts a 1331 pin AM4 socket up top with four DDR4 slots to the right. The CMOS battery is placed just above the PCI-E slots in a position that Morry would be proud of (so long as your CPU cooler is not too massive). Below that are two PCI-E 3.0 x16 slots (electrically x16/x4 or x8/x8), a single PCI-E 3.0 x1 slot, and a NVMe M.2 (PCI-E) slot. The bottom right corner of the board hosts six SATA 6 Gbps ports.

Rear I/O on the AMD motherboard includes:

  • 2 x USB 2.0
  • 1 x PS/2
  • 3 x Video Outputs
    • 1 x VGA
    • 1 x DVI
    • 1 x HDMI
  • 4 x USB 3.0
  • 2 x USB 3.1
  • 1 x Gigabit Ethernet                
  • 3 x Audio Jacks

Several websites are reporting that AMD will be unleashing the floodgates of socket AM4 motherboards using the A320 and B350 chipsets in October (it is saving the launch of the enthusiast X370 chipset for next year alongside Summit Ridge). I have to say that it is nice to see an AMD motherboard with updated I/O which is a nice change from the ancient 990X AM3+ platform and even the FM2+ motherboards which were newer but still .ot as full featured as the competition.
