MSI is in full force at CES 2017 this year and in addition to external GPU docks, laptops, and a wall of Z270 motherboards, the company is using the event to show off its AM4 motherboards for the first time. At the top of the pack is the flagship X370 XPower Gaming Titanium clad in shimmering white and black and ready to support AMD’s upcoming “Ryzen” processors based on the Zen architecture.

Armed with AMD’s highest end X370 chipset, the flagship motherboard supports Ryzen CPUs as well as 7th generation APUs. There are four DDR4 memory slots on the board that MSI claims can operate in dual channel mode at up to 2667 MHz when overclocked. The board is rather powerful as well in that there are a lot of power connections. The usual 24-pin ATX and 8-pin EPS are joined by a 4-pin ATX up top and a 6-pin PCI-E connector on the bottom to stabilize overclocks. Further, a 10-phase VRM drives the AM4 socket and memory.
The motherboard further features three PCI-E x16 slots, three PCI-E x1 slots, two M.2 (32 Gb/s), one U.2 (32 Gb/s), and six SATA 6 Gbps ports. On the PCI-E front, the first two slots are connected to the processor and run at x8 when both slots are populated while the third slot is connected to the chipset and is electrically x4. As far as the SATA ports, two are directly connected to the processor and four come from the chipset.
MSI is including their own onboard audio solution called Audio Boost 4 as well as Gigabit Ethernet though the Steel Armor is covering the chips so it is hard to say exactly what they are using there. Also, Multi GPU setups are officially supported up to two way SLI HB or three way CrossFireX.
There is a plethora of USB support here with the X370 XPower Gaming Titanium supporting up to four USB 3.1 (one Type-C, three Type-A), eight USB 3.0, and seven USB 2.0 ports. If that is not enough, then you may have an addition to PC accessories (or just really like those USB missle batteries hehe).
Naturally, MSI is staying silent on pricing and availability of the motherboard(s) but I hope to see them out within the first half of the year! The design is certainly polarizing, but the features are there. I look forward to reading our review of this and other AM4 motherboards and how they fare at overclocking!

High Bandwidth Cache
Apart from AMD’s other new architecture due out in 2017, its Zen CPU design, there is no other product that has had as much build up and excitement surrounding it than its Vega GPU architecture. After the world learned that Polaris would be a mainstream-only design that was released as the Radeon RX 480, the focus for enthusiasts came straight to Vega. It’s been on the public facing roadmaps for years and signifies the company’s return to the world of high end GPUs, something they have been missing since the release of the Fury X in mid-2015.
Let’s be clear: today does not mark the release of the Vega GPU or products based on Vega. In reality, we don’t even know enough to make highly educated guesses about the performance without more details on the specific implementations. That being said, the information released by AMD today is interesting and shows that Vega will be much more than simply an increase in shader count over Polaris. It reminds me a lot of the build to the Fiji GPU release, when the information and speculation about how HBM would affect power consumption, form factor and performance flourished. What we can hope for, and what AMD’s goal needs to be, is a cleaner and more consistent product release than how the Fury X turned out.
The Design Goals
AMD began its discussion about Vega last month by talking about the changes in the world of GPUs and how the data sets and workloads have evolved over the last decade. No longer are GPUs only worried about games, but instead they must address profession workloads, enterprise workloads, scientific workloads. Even more interestingly, as we have discussed the gap in CPU performance vs CPU memory bandwidth and the growing gap between them, AMD posits that the gap between memory capacity and GPU performance is a significant hurdle and limiter to performance and expansion. Game installs, professional graphics sets, and compute data sets continue to skyrocket. Game installs now are regularly over 50GB but compute workloads can exceed petabytes. Even as we saw GPU memory capacities increase from Megabytes to Gigabytes, reaching as high as 12GB in high end consumer products, AMD thinks there should be more.
Coming from a company that chose to release a high-end product limited to 4GB of memory in 2015, it’s a noteworthy statement.
The High Bandwidth Cache
Bold enough to claim a direct nomenclature change, Vega 10 will feature a HBM2 based high bandwidth cache (HBC) along with a new memory hierarchy to call it into play. This HBC will be a collection of memory on the GPU package just like we saw on Fiji with the first HBM implementation and will be measured in gigabytes. Why the move to calling it a cache will be covered below. (But can’t we call get behind the removal of the term “frame buffer”?) Interestingly, this HBC doesn’t have to be HBM2 and in fact I was told that you could expect to see other memory systems on lower cost products going forward; cards that integrate this new memory topology with GDDR5X or some equivalent seem assured.

Tonight at CES AMD announced 16 new AM4 motherboards from five manufacturers and new PCs from over a dozen system builders. The motherboards will all bring support for dual channel DDR4 memory, NVMe, M.2 SATA devices and USB 3.1 support for AMD users. You can also expect at least 24 lanes of PCIe 3.0, perhaps more if we can spot some with bridge chips.
The MSI A320 Pro-VD and B350 Tomahawk (not to scale)
MSI will be showing off their A320M Pro-VD, X370 XPower Gaming Titanium, B350 Tomahawk and B350M Mortar.
Gigabyte's GA-X370 Gaming K5, GA-AX370-Gaming 5 and GA-AB350-Gaming 3.
The gang should have updates on the full lineup soon including the Gigabyte A320M-HD3 not pictured above.
Biostar's X370 GT7 TOP and B350 GT3 TOP
ASRock's ASRock Fatal1ty X370 Professional Gaming and X370 Taichi.
There are more models on display and ASUS did announce the Asus B350M-C though we did not yet get a picture of it. All motherboards will offer compatibility with at least some existing coolers, we know for a fact that Corsair's Hydro H60, H100i and H110i as well as Noctua's NH-U12S, NHL9x65 and D15 will all be supported.

Since the initial FreeSync launch in March of 2015, AMD has quickly expanded the role and impact that the display technology has had on the market. Technologically, AMD added low frame rate compensation (LFC) to mimic the experience of G-Sync displays, effectively removing the bottom limit to the variable refresh rate. LFC is an optional feature that requires a large enough gap between the displays minimum and maximum refresh rates to be enabled, but the monitors that do integrate it work well. Last year AMD brought FreeSync to HDMI connections too by overlaying the standard as an extension. This helped to expand the quantity and lower the price of available FreeSync options. Most recently, AMD announced that borderless windowed mode was being added as well, another feature-match to what NVIDIA can do with G-Sync.
The biggest feather in the cap for AMD FreeSync is the sheer quantity of displays that exist on the market that support it. As of our briefing in early December, AMD claimed 121 design wins for FreeSync to just 18 for NVIDIA G-Sync. I am not often in the camp of quantity over quality, but the numbers are impressive. The pervasiveness of FreeSync monitors means that at least some of them are going to be very high quality integrations and that prices are going to be lower compared to the green team’s selection.
Today AMD is announcing FreeSync 2, a new, concurrently running program that adds some new qualifications to displays for latency, color space and LFC. This new program will be much more hands-on from AMD, requiring per-product validation and certification and this will likely come at a cost. (To be clear, AMD hasn’t confirmed if that is the case to me yet.)
Let’s start with the easy stuff first: latency and LFC. FreeSync 2 will require monitors to support LFC and thus to have no effective bottom limit to their variable refresh rate. AMD will also instill a maximum latency allowable for FS2, on the order of “a few milliseconds” from frame buffer flip to photon. This can be easily measured with some high-speed camera work by both AMD and external parties (like us).
These are fantastic additions to the FreeSync 2 standard and should drastically increase the quality of panels and product.
The bigger change to FreeSync 2 is on the color space. FS2 will require a doubling of the perceivable brightness and doubling of the viewable color volume based on the sRGB standards. This means that any monitor that has the FreeSync 2 brand will have a significantly larger color space and ~400 nits brightness. Current HDR standards exceed these FreeSync 2 requirements, but there is nothing preventing monitor vendors from exceeding these levels; they simply set a baseline that users should expect going forward.
In addition to just requiring the panel to support a wider color gamut, FS2 will also enable user experience improvements as well. First, each FS2 monitor must communicate its color space and brightness ranges to the AMD driver through a similar communication path used today for variable refresh rate information. By having access to this data, AMD can enable automatic mode switches from SDR to HDR/wide color gamut based on the application. Windows can remain in a basic SDR color space but games or video applications that support HDR modes can enter that mode without user intervention.
Color space mapping can take time in low power consumption monitors, adding potential latency. For movies that might not be an issue, but for enthusiast gamers it definitely is. The solution is to do all the tone mapping BEFORE the image data is sent to the monitor itself. But with varying monitors, varying color space limits and varying integrations of HDR standards, and no operating system level integration for tone mapping, it’s a difficult task.
The solution is for games to map directly to the color space of the display. AMD will foster this through FreeSync 2 – a game that integrates support for FS2 will be able to get data from the AMD driver stack about the maximum color space of the attached display. The engine can then do its tone mapping to that color space directly, rather than some intermediate state, saving on latency and improving the gaming experience. AMD can then automatically switch the monitor to its largest color space, as well as its maximum brightness. This does require the game engine or game developer to directly integrate support for this feature though – it will not be a catch-all solution for AMD Radeon users.
This combination of latency, LFC and color space additions to FreeSync 2 make it an incredibly interesting standard. Pushing specific standards and requirements on hardware vendors is not something AMD has had the gall to do the past, and honestly the company has publicly been very against it. But to guarantee the experience for Radeon gamers, AMD and the Radeon Technologies Group appear to be willing to make some changes.
NVIDIA has yet to make any noise about HDR or color space requirements for future monitors and while the FreeSync 2 standards shown here don’t quite guarantee HDR10/Dolby Vision quality displays, they do force vendors to pay more attention to what they are building and create higher quality products for the gaming market.
All GPUs that support FreeSync will support FreeSync 2 and both programs will co-exist. FS2 is currently going to be built on DisplayPort and could find its way into another standard extension (as Adaptive Sync was). Displays are set to be available in the first half of this year.

Tagged: Vega, amd
Just ahead of CES, AMD has published a teaser page with, currently, a single YouTube video and a countdown widget. In the video, a young man is walking down the street while tapping on a drum and passing by Red Team propaganda posters. It also contains subtle references to Vega on walls and things, in case the explicit references, including the site’s URL, weren’t explicit enough.
How subtle, AMD.
Speaking of references to Vega, the countdown widget claims to lead up to the architecture preview. We were expecting AMD to launch their high-end GPU line at CES, and this is the first (official) day of the show. Until it happens, I don’t really know whether it will be a more technical look, or if they will be focusing on the use cases.
The countdown ends at 9am (EST) on January 5th.

Tagged: graphics drivers, amd
Last week, AMD came down to the PC Perspective offices to show off their new graphics drivers, which introduced optional game capture software (and it doesn’t require a login to operate). This week, they are publishing a new version of it, Radeon Software Crimson ReLive Edition 16.12.2, which fixes a huge list of issues.
While most of these problem were minor, the headlining fix could have been annoying for FreeSync users (until this update fixed it, of course). It turns out that, when using FreeSync with a borderless fullscreen application, and another monitor has an active window, such as a video in YouTube, the user would experience performance issues in the FreeSync application (unless all of these other windows were minimized). This sounds like a lot of steps, but you could imagine how many people have a YouTube or Twitch stream running while playing a semi-casual game. Also, those types of games lend themselves well to being run in borderless window mode, too, so you can easily alt-tab to the other monitors, exacerbating the issue. Regardless, it’s fixed now.
Other fixed issues involve mouse pointer corruption with an RX 480 and multi-GPU issues in Battlefield 1. You can download them at AMD's website.

Hardware/Software Picks of the Week
Ryzen coming in 2017
As much as we might want it to be, today is not the day that AMD launches its new Zen processors to the world. We’ve been teased with it for years now, with trickles of information at event after event…but we are going to have to wait a little bit longer with one more tease at least. Today’s AMD is announcing the official branding of the consumer processors based on Zen, previously code named Summit Ridge, along with a clock speed data point and a preview of five technology that will help it be competitive with the Intel Core lineup.
The future consumer desktop processor from AMD will now officially be known as Ryzen. That’s pronounced “RISE-IN” not “RIS-IN”, just so we are all on the same page. CEO Lisa Su was on stage during the reveal at a media event last week and claimed that while media, fans and AMD fell in love with the Zen name, it needed a differentiation from the architecture itself. The name is solid – not earth shattering though I foresee a long life of mispronunciation ahead of it.
Now that we have the official branding behind us, let’s get to the rest of the disclosed information we can reveal today.
We already knew that Summit Ridge would ship with an 8 core, 16 thread version (with lower core counts at lower prices very likely) but now we know a frequency and a cache size. AMD tells us that there will be a processor (the flagship) that will have a base clock of 3.4 GHz with boost clocks above that. How much above that is still a mystery – AMD is likely still tweaking its implementation of boost to get as much performance as possible for launch. This should help put those clock speed rumors to rest for now.
The 20MB of cache matches the Core i7-6900K, though obviously with some dramatic architecture differences between Broadwell and Zen, the effect and utilization of that cache will be interesting measure next year.
We already knew that Ryzen will be utilizing the AM4 platform, but it’s nice to see it reiterated a modern feature set and expandability. DDR4 memory, PCI Express Gen3, native USB 3.1 and NVMe support – there are all necessary building blocks for a modern consumer and enthusiast PC. We still should see how many of these ports the chipset offers and how aggressive motherboard companies like ASUS, MSI and Gigabyte are in their designs. I am hoping there are as many options as would see for an X99/Z170 platform, including budget boards in the $100 space as well as “anything and everything” options for those types of buyers that want to adopt AMD’s new CPU.

Ryan was not the only one at AMD's Radeon Instinct briefing, covering their shot across NVIDIA's HPC products. The Tech Report just released their coverage of the event and the tidbits which AMD provided about the MI25, MI8 and MI6; no relation to a certain British governmental department. They focus a bit more on the technologies incorporated into GEMM and point out that AMD's top is not matched by an NVIDIA product, the GP100 GPU does not come as an add-in card. Pop by to see what else they had to say.
"Thus far, Nvidia has enjoyed a dominant position in the burgeoning world of machine learning with its Tesla accelerators and CUDA-powered software platforms. AMD thinks it can fight back with its open-source ROCm HPC platform, the MIOpen software libraries, and Radeon Instinct accelerators. We examine how these new pieces of AMD's machine-learning puzzle fit together."
