A report from VideoCardz.com claims that NVIDIA is working on another GTX 950 graphics card, but not the 950 Ti you might have expected.
Reference GTX 950 (Image credit: NVIDIA)
While the GTX 750 Ti was succeeded by the GTX 950 in August of last year, the higher specs for this new GPU came at the cost of a higher TDP (90W vs. 60W). This new rumored GTX 950, which might be called either 950 SE or 950 LP according to the report, would be a lower power version of the GTX 950, and would actually have a lot more in common with the outgoing GTX 750 Ti than the plain GTX 750 as we can see from this chart:
(Image credit: VideoCardz)
As you can see the GTX 750 Ti is based on GM107 (Maxwell 1.0) and has 640 CUDA cores, 40 TUs, 16 ROPs, and it operates at 1020 MHz Base/1085 MHz Boost clocks. The reported specs of this new GTX 950 SE/LP would be nearly identical, though based on GM206 (Maxwell 2.0) and offering greater memory bandwidth (and slightly higher power consumption).
The VideoCardz report was sourced from Expreview, which claimed that this GTX 950 SE/LP product would arrive next month at some point. This report is a little more vague than some of the rumors we see, but it could very well be that NVIDIA has a planned replacement for the remaining Maxwell 1.0 products on the market. I would have personally expected to see a"Ti” product before any “LE/LP” version of the GTX 950, and this reported name seems more like an OEM product than a retail part. We will have to wait and see if this report is accurate.

You might wonder what makes a graphics card “designed for VR,” but this is actually quite interesting. Rather than plugging your headset into the back of your desktop, EVGA includes a 5.25” bay that provides 2x USB 3.0 ports and 1x HDMI 2.0 connection. The use case is that some users will want to easily connect and disconnect their VR devices, which, knowing a few indie VR developers, seems to be a part of their workflow. The same may be true of gamers, but I'm not sure.
While the bay allows for everything, including the HDMI plug via an on-card port, to be connected internally, you will need a spare USB 3.0 header on your motherboard to hook it up. It would have been interesting to see whether EVGA could have attached a USB 3.0 controller on the add-in board, but that might have been impossible (or unpractical) given that the PCIe connector would need to be shared with the GPU (not to mention the complexity of also adding a USB 3.0 controller to the board). Also, I expect motherboards should have at least one. If not, you can find USB 3.0 add-in cards with internal headers.
The card comes in two sub-versions, one with the NVIDIA-style blower cooler, and the other with EVGA's ACX 2.0+ cooler. I tend to prefer exposed fan GPUs because they're easier to blow air into after a few years, but you might have other methods to control dust.
Both are currently available for $699.99 on Newegg.com, while Amazon only lists the ACX2.0+ cooler version, and that's out of stock. It is also $699.99, though, so that should be what to expect.

If you don't have a lot of cash on hand for games or hardware, a 4k adaptive sync monitor with two $600 GPUs and a collection of $80 AAA titles simply isn't on your radar. That doesn't mean you have to toss in your love of gaming for occasional free to play gaming sessions; you just have to adapt. A prime example are those die hard Skyrim fans who have modded the game to oblivion over the past few years, with many other games and communities that may not be new but are still thriving. Chances are that you are playing at 1080p so a high powered GPU is not needed, however mods that upscale textures and many others do love huge tracts of RAM.
So for those outside of North America looking for a card they can afford after a bit of penny pinching, check out Legion Hardware's review of the 4GB version of the Gainward GTX 960 Phantom. It won't break any benchmarking records but it will let you play the games you love and even new games as their prices inevitably decrease over time.
Today we are checking out Gainward’s premier GeForce GTX 960 graphics card, the Phantom 4GB. Equipped with twice the memory buffer of standard cards, it is designed for extreme 1080p gaming. Therefore it will be interesting to see how the Phantom 4GB compares to a 2GB GTX 960..."

AMD made an interesting enterprise announcement today with the introduction of new FirePro S-Series graphics cards that integrate hardware-based virtualization technology. The new FirePro S1750 and S1750 x2 are aimed at virtualized workstations, render farms, and cloud gaming platforms where each virtual machine has direct access to the graphics hardware.
The new graphics cards use a GCN-based Tonga GPU with 2,048 stream processors paired with 8GB of ECC GDDR5 memory on the single slot FirePro S1750. The dual slot FirePro S1750 x2, as the name suggests, is a dual GPU card that features a total of 4,096 shaders (2,048 per GPU) and 16 GB of ECC GDDR5 (8 GB per GPU). The S1750 has a TDP of 150W while the dual-GPU S1750 x2 variant is rated at 265W and either can be passively cooled.
Where the graphics cards get niche is the inclusion of what AMD calls MxGPU (Multi-User GPU) technology which is derived from the SR-IOV (Single Root Input/Output Virtualization) PCI-Express standard. According to AMD, the new FirePro S-Series allows virtual machines direct access to the full range of GPU hardware (shaders, memory, ect.) and OpenCL 2.0 support on the software side. The S1750 supports up to 16 simultaneous users and the S1750 x2 tops out at 32 users. Each virtual machine is allocated an equal slice of the GPU, and as you add virtual machines the equal slices get smaller. AMD’s solution to that predicament is to add more GPUs to spread out the users and allocate each VM more hardware horsepower. It is worth noting that AMD has elected not to charge companies any per-user licensing fees for all these VMs the hardware supports which should make these cards more competitive.
The graphics cards use ECC memory to correct errors when dealing with very large numbers and calculations and every VM is reportedly protected and isolated such that one VM can not access any data of a different VM stored in graphics memory.
I am interested to see how these stack up compared to NVIDIA’s GRID and VGX GPU virtualization specialized graphics cards. The difference between the software versus hardware-based virtualization may not make much difference, but AMD’s approach may be every so slightly more efficient with the removal of layer between the virtual machine and hardware. We’ll have to wait and see, however.
Enterprise users will be able to pick up the new cards installed in systems from server manufacturers sometime in the first half of 2016. Pricing for the cards themselves appears to be $2,399 for the single GPU S1750 and $3,999 for the dual GPU S1750 x2.
Needless to say, this is all a bit more advanced (and expensive!) than the somewhat finicky 3D acceleration option desktop users can turn on in VMWare and VirtualBox! Are you experimenting with remote workstations and virtual machines for thin clients that can utilize GPU muscle? Does AMD’s MxGPU approach seem promising?

Lo and behold! The dual-Fiji card that we have previous dubbed the AMD Radeon Fury X2 still lives! Based on a tweet from AMD PR dude Antal Tungler, a PC from Falcon Northwest at the VRLA convention was utilizing a dual-GPU Fiji graphics card to power some demos.
— Antal Tungler (@coloredrocks) January 23, 2016
This prototype Falcon Northwest Tiki system was housing the GPU beast but no images were shown of the interior of the system. Still, it's good to see AMD at least recognize that this piece of hardware still exists at all, since it was initially promised to the enthusiast market by "fall of 2015." Even in October we had hints that the card might be coming soon after seeing some shipping manifests leak out to the web.
Better late than never, right? One theory floating around inside the offices here is that AMD is going to release the Fury X2 along with the VR headsets coming out this spring, with hopes of making it THE VR graphics card of choice. The value of using multi-GPU for VR is interesting, with one GPU dedicated to each eye, though the pitfalls that could haunt both AMD and NVIDIA in this regard (latency, frame time consistency) make the technological capability a debate.

Tagged: Polaris, pascal, nvidia, jedec, gddr5x, GDDR5, amd
Though information about the technology has been making rounds over the last several weeks, GDDR5X technology finally gets official with an announcement from JEDEC this morning. The JEDEC Solid State Foundation is, as Wikipedia tells us, an "independent semiconductor engineering trade organization and standardization body" that is responsible for creating memory standards. Getting the official nod from the org means we are likely to see implementations of GDDR5X in the near future.
The press release is short and sweet. Take a look.
ARLINGTON, Va., USA – JANUARY 21, 2016 –JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of JESD232 Graphics Double Data Rate (GDDR5X) SGRAM. Available for free download from the JEDEC website, the new memory standard is designed to satisfy the increasing need for more memory bandwidth in graphics, gaming, compute, and networking applications.
Derived from the widely adopted GDDR5 SGRAM JEDEC standard, GDDR5X specifies key elements related to the design and operability of memory chips for applications requiring very high memory bandwidth. With the intent to address the needs of high-performance applications demanding ever higher data rates, GDDR5X is targeting data rates of 10 to 14 Gb/s, a 2X increase over GDDR5. In order to allow a smooth transition from GDDR5, GDDR5X utilizes the same, proven pseudo open drain (POD) signaling as GDDR5.
“GDDR5X represents a significant leap forward for high end GPU design,” said Mian Quddus, JEDEC Board of Directors Chairman. “Its performance improvements over the prior standard will help enable the next generation of graphics and other high-performance applications.”
JEDEC claims that by using the same signaling type as GDDR5 but it is able to double the per-pin data rate to 10-14 Gb/s. In fact, based on leaked slides about GDDR5X from October, JEDEC actually calls GDDR5X an extension to GDDR5, not a new standard. How does GDDR5X reach these new speeds? By doubling the prefech from 32 bytes to 64 bytes. This will require a redesign of the memory controller for any processor that wants to integrate it.
Image source: VR-Zone.com
As for usable bandwidth, though information isn't quoted directly, it would likely see a much lower increase than we are seeing in the per-pin statements from the press release. Because the memory bus width would remain unchanged, and GDDR5X just grabs twice the chunk sizes in prefetch, we should expect an incremental change. No mention of power efficiency is mentioned either and that was one of the driving factors in the development of HBM.
Performance efficiency graph from AMD's HBM presentation
I am excited about any improvement in memory technology that will increase GPU performance, but I can tell you that from my conversations with both AMD and NVIDIA, no one appears to be jumping at the chance to integrate GDDR5X into upcoming graphics cards. That doesn't mean it won't happen with some version of Polaris or Pascal, but it seems that there may be concerns other than bandwidth that keep it from taking hold.

It's nice to see long-term roundups every once in a while. They do not really provide useful information for someone looking to make a purchase, but they show how our industry is changing (or not). In this case, Phoronix tested twenty-seven NVIDIA GeForce cards across four architectures: Tesla, Fermi, Kepler, and Maxwell. In other words, from the GeForce 8 series all the way up to the GTX 980 Ti.

Nine years of advancements in ASIC design, with a doubling time-step of 18 months, should yield a 64-fold improvement. The number of transistors falls short, showing about a 12-fold improvement between the Titan X and the largest first-wave Tesla, although that means nothing for a fabless semiconductor designer. The main reason why I include this figure is to show the actual Moore's Law trend over this time span, but it also highlights the slowdown in process technology.
Performance per watt does depend on NVIDIA though, and the ratio between the GTX 980 Ti and the 8500 GT is about 72:1. While this is slightly better than the target 64:1 ratio, these parts are from very different locations in their respective product stacks. Swapping the 8500 GT for the following year's 9800 GTX, which leads to a comparison between top-of-the-line GPUs of their respective times, and you see a 6.2x improvement in performance per watt versus the GTX 980 Ti. On the other hand, that part was outstanding for its era.
I should note that each of these tests take place on Linux. It might not perfectly reflect the landscape on Windows, but again, it's interesting in its own right.

Digitimes is reporting on statements that were allegedly made by TSMC co-CEO, Mark Liu. We are currently seeing 16nm parts come out of the foundry, which is expected to be used in the next generation of GPUs, replacing the long-running 28nm node that launched with the GeForce GTX 680. (It's still unannounced whether AMD and NVIDIA will use 14nm FinFET from Samsung or GlobalFoundries, or 16nm FinFET from TSMC.)
Update (Jan 20th, @4pm EST): Couple minor corrections. Radeon HD 7970 launched at 28nm first by a couple of months. I just remember NVIDIA getting swamped in delays because it was a new node, so that's probably why I thought of the GTX 680. Also, AMD announced during CES that they will use GlobalFoundries to fab their upcoming GPUs, which I apparently missed. We suspect that NVIDIA will use TSMC, and have assumed that for a while, but it hasn't been officially announced yet (if ever).
According to their projections, which (again) are filtered through Digitimes, the foundry expects to have 7nm in the first half of 2018. They also expect to introduce extreme ultraviolet (EUV) lithography methods with 5nm in 2020. Given that Silicon in a solid has a lattice spacing of ~0.54nm at room temperature, 7nm transistors will consist of about 13 atoms, and 5nm transistors will have features containing about 9 atoms.
We continue the march toward the end of silicon lithography.
Even if the statement is correct, much can happen between then and now. It wouldn't be the first time that I've seen a major foundry believe that a node would be available, but end up having it delayed. I wouldn't hold my breath, but I might cross my fingers if my hands were free.
At the very least, we can assume that TSMC's roadmap is 16nm, 10nm, 7nm, and then 5nm.

Tagged: Samsung, HBM2, hbm
Samsung has just announced that they have begun mass production of 4GB HBM2 memory modules. When used on GPUs, four packages can provide 16GB of Video RAM with very high performance. They do this with a very wide data bus, which trade off frequency for transferring huge chunks. Samsung's offering is rated at 256 GB/s per package, which is twice what the Fury X could do with HBM1.
They also expect to mass produce 8GB HBM2 packages within this calendar year. I'm guessing that this means we'll see 32GB GPUs in the late-2016 or early-2017 time frame unless "within this year" means very, very soon (versus Q3/Q4). They will likely be for workstation or professional cards, but, in NVIDIA's case, those are usually based on architectures that are marketed to high-end gaming enthusiasts through some Titan offering. There's a lot of ways this could go, but a 32GB Titan seems like a bit much; I wouldn't expect that this affects the enthusiast gamer segment. It might mean that professionals looking to upgrade from the Kepler-based Tesla K-series might be waiting a little longer, maybe even GTC 2017. Alternatively, they might get new cards, just with a 16GB maximum until a refresh next year. There's not enough information to know one way or the other, but it's something to think about when more of it starts rolling in.
Samsung's HBM2 are compatible with ECC, although I believe that was also true for at least some HBM1 modules from SK Hynix.

NVIDIA is reportedly preparing faster mobile GPUs based on Maxwell, with a GTX 980MX and 970MX on the way.
The new GTX 980MX would sit between the GTX 980M and the laptop version of the full GTX 980, with 1664 CUDA cores (compared to 1536 with the 980M), 104 Texture Units (up from the 980M's 96), a 1048 MHz core clock, and up to 8 GB of GDDR5. Memory speed and bandwidth will reportedly be identical to the GTX 980M at 5000 MHz and 160 GB/s respectively, with both GPUs using a 256-bit memory bus.
The GTX 970MX represents a similar upgrade over the existing GTX 970M, with CUDA Core count increased from 1280 to 1408, Texture Units up from 80 to 88, and 8 additional raster devices available (56 vs. 48). Both the 970M and 970MX use 192-bit GDDR5 clocked at 5000 MHz, and available with the same 3 GB or 6 GB of frame buffer.
WCCFtech prepared a chart to demonstrate the differences between NVIDIA's mobile offerings:
|Model||GeForce GTX 980 Laptop Version||GeForce GTX 980MX||
GeForce GTX 980M
|GeForce GTX 970MX||GeForce GTX 970M||GeForce GTX 965M||
GeForce GTX 960M
|Clock Speed||1218 MHz||1048 MHz||1038 MHz||941 MHz||924 MHz||950 MHz||1097 MHz|
|Frame Buffer||8 GB GDDR5||8/4 GB GDDR5||8/4 GB GDDR5||6/3 GB GDDR5||6/3 GB GDDR5||4 GB GDDR5||4 GB GDDR5|
|Memory Frequency||7008 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz||5000 MHz|
|Memory Bandwidth||224 GB/s||160 GB/s||160 GB/s||120 GB/s||120 GB/s||80 GB/s||80 GB/s|
These new GPUs will reportedly be based on the same Maxwell GM204 core, and TDPs are apparently unchanged at 125W for the GTX 980MX, and 100W for the 970MX.
We will await any official announcement.

Tagged: Polaris, amd
When AMD announced their Polaris architecture at CES, it was focused on mid-range applications. Their example was an add-in board that could compete against an NVIDIA GeForce GTX 950, 1080p60 medium settings in Battlefront, but do so at 39% less wattage than this 28nm, Maxwell chip. These Polaris chips are planned for a “mid 2016” launch.
Raja Koduri, Chief Architect for the Radeon Technologies Group, spoke with VentureBeat at the show. In his conversation, he mentioned two architectures, Polaris 10 and Polaris 11, in the context of a question about their 2016 product generation. In the “high level” space, they are seeing “the most revolutionary jump in performance so far.” This doesn't explicitly state that the high-end Polaris video card will launch in 2016. That said, when combined with the November announcement, covered by us as “AMD Plans Two GPUs in 2016,” it further supports this interpretation.
We still don't know much about what the actual performance of this high-end GPU will be, though. AMD was able to push 8 TeraFLOPs of compute throughput by creating a giant 28nm die and converting the memory subsystem to HBM, which supposedly requires less die complexity than a GDDR5 memory controller (according to a conference call last year that preceded Fury X). The two-generation jump will give them more complexity to work with, but that could be partially offset by a smaller die because of the potential differences in yields (and so forth).
Also, while the performance of the 8 TeraFLOP Fury X was roughly equivalent to NVIDIA's 5.6 TeraFLOP GeForce GTX 980 Ti, we still don't know why. AMD has redesigned a lot of their IP blocks with Polaris; you would expect that, if something unexpected was bottlenecking Fury X, the graphics manufacturer wouldn't overlook it the next chance that they are able to tweak it. This could have been graphics processing or something much more mundane. Either way, upcoming benchmarks will be interesting.
And it seems like that may be this year.

Tagged: graphics drivers, amd
AMD's recent “Hotfix” drivers don't seem to mean what NVIDIA's does. In the Green Team's case, they usually fix one or two issues that slipped past QA. While they likely won't break anything, they are probably a bad idea to install if you're not experiencing the listed problems. The changelog on AMD's drivers are significantly longer with a list of known issues that is roughly the same size.
So should you install it? That depends. It's a little less cut-and-dry than NVIDIA's hotfixes, which are only useful for a handful of people. It sounds like the worst known issue is “Game stuttering may be experienced when running two Radeon R9 295X2 graphics cards in CrossFire mode” and “Display corruption may occur on multiple display systems when it has been running idle for some time.” The latter would affect me greatly, because I run four displays and basically never sleep or shutdown (except for updates). On the other hand, it fixes a variety of crash, hang, and flicker issues.
Check it out. If it sounds good, then pick it up. Otherwise, wait for the next Beta or WHQL driver.

NVIDIA has been pushing for WHQL certification for their drivers, but sometimes issues slip through QA, both at Microsoft and their own, internal team(s). Sometimes these issues will be fixed in a future release, but sometimes they push out a “HotFix” driver immediately. This is often great for people who experience the problems, but they should not be installed otherwise.
In this case, GeForce Hotfix driver 361.60 fixes two issues. One is listed as “install & clocking related issues,” which refers to the GPU memory clock. According to Manuel Guzman of NVIDIA, some games and software was not causing the driver to fully wake the memory clock to a high-performance state. The other issue is “Crashes in Photoshop & Illustrator,” which fixes blue screen issues in both software, and possibly other programs that use the GPU in similar ways. I've never seen GeForce Driver 361.43 cause a BSOD in Photoshop, but I am a few versions behind with CS5.5.
Download links are available at NVIDIA Support, but unaffected users should just wait for an official driver in case the patch causes other issues, due to its minimal QA.

A delivery of GPUs and related test equipment from Taiwan to Banglore has led to speculation about NVIDIA's upcoming GP104 Pascal GPU.
Image via Zauba.com
How much information can be gleaned from an import shipping manifest (linked here)? The data indicates a chip with a 37.5 x 37.5 mm package and 2152 pins, which is being attributed to the GP104 based on knowledge of “earlier, similar deliveries” (or possible inside information). This has prompted members of the 3dcenter.org forums (German language) to speculate on the use of GDDR5 or GDDR5X memory based on the likelihood of HBM being implemented on a die of this size.
Of course, NVIDIA has stated that Pascal will implement 3D memory, and the upcoming GP100 will reportedly be on a 55 x 55 mm package using HBM2. Could this be a new, lower-cost part using the existing GDDR5 standard or the faster GDDR5X instead? VideoCardz and WCCFtech have posted stories based on the 3DCenter report, and to quote directly from the VideoCardz post on the subject:
"3DCenter has a theory that GP104 could actually not use HBM, but GDDR5(X) instead. This would rather be a very strange decision, but could NVIDIA possibly make smaller GPU (than GM204) and still accommodate 4 HBM modules? This theory is not taken from the thin air. The GP100 aka the Big Pascal, would supposedly come in 55x55mm BGA package. That’s 10mm more than GM200, which were probably required for additional HBM modules. Of course those numbers are for the whole package (with interposer), not just the GPU."
All of this is a lot to take from a shipping record that might not even be related to an NVIDIA product, but the report has made the rounds at this point so now we’ll just have to wait for new information.

AMD has announced a price cut for the Radeon R9 Nano, which will now have a suggested price of $499, a $150 drop from the original $649 MSRP.
VideoCardz had the story this morning, quoting the official press release from AMD:
"This past September, the AMD Radeon™ R9 Nano graphics card launched to rave reviews, claiming the title of the world’s fastest and most power efficient Mini ITX gaming card, powered by the world’s most advanced and innovative GPU with on-chip High-Bandwidth Memory (HBM) for incredible 4K gaming performance. There was nothing like it ever seen before, and today, it remains in a class of its own, delivering smooth, true-to-life, premium 4K and VR gaming in a small form factor PC.
At a peak power of 175W and in a 6-inch form factor, it drives levels of performance that are on par with larger, more power-hungry GPUs from competitors, and blows away Mini ITX competitors with up to 30 percent better performance than the GTX 970 Mini ITX.
As of today, 11 January, this small card will have an even bigger impact on gamers around the world as AMD announces a change in the AMD Radeon™ R9 Nano graphics card’s SEP from $649 to $499. At the new price, the AMD Radeon™ R9 Nano graphics card will be more accessible than ever before, delivering incredible performance and leading technologies, with unbelievable efficiency in an astoundingly small form factor that puts it in a class all of its own."
The R9 Nano (reviewed here) had been the most interesting GPU released in 2015 to the team at PC Perspective. It was a compelling product for its tiny size, great performance, and high power efficiency, but the dialogue here probably mirrored that of a lot of potential buyers; for the price of a Fury X, did it make sense to buy the Nano? It was all going to depend on need, but very few enclosures on the market do not support a full-length GPU, as we discovered when testing out small R9 Nano builds.
Now that the price will move down $150 it becomes an easier choice: $499 will buy you a full R9 Fury X core for $150 less. The performance of a Fury X is only a few percentage points higher than the slighly lower-clocked Nano, so you're now getting most of the way there for much less. We have seen some R9 Fury X cards selling for $599, but even at $100 more would you buy the Fury X over a Nano? If nothing else the lower price makes the conversation a lot more interesting.

If you remember back when Far Cry 4 launched, it required a quad-core processor. It would block your attempts to launch the game unless it detected four CPU threads, either native quad-core or dual-core with two SMT threads per core. This has naturally been hacked around by the PC gaming community, but it is not supported by Ubisoft. It's also, apparently, a bad experience.
The follow-up, Far Cry Primal, will be released in late February. Oddly enough, it has similar, but maybe slightly lower, system requirements. I'll list them, and highlight the differences.
- 64-bit Windows 7, 8.1, or 10 (basically unchanged from 4)
- Intel Core i3-550 (down from i5-750)
- or AMD Phenom II X4 955 (unchanged from 4)
- 4GB RAM (unchanged from 4)
- 1GB NVIDIA GTX 460 (unchanged from 4)
- or 1GB AMD Radeon HD 5770 (down from HD 5850)
- 20GB HDD Space (down from 30GB)
- Intel Core i7-2600K (up from i5-2400S)
- or AMD FX-8350 (unchanged from 4)
- 8GB of RAM (unchanged from 4)
- NVIDIA GeForce GTX 780 (up from GTX 680)
- or AMD Radeon R9 280X (down from R9 290X)
While the CPU is interesting, the opposing directions of the recommended GPU is fascinating. Either the parts are within Ubisoft's QA margin of error, or they increased the GPU load, but were able to optimize AMD better than Far Cry 4, which was a net gain in performance (and explains the slight bump in CPU power required to feed the extra content). Of course, either way is just a guess.
Back on the CPU topic though, I would be interested to see the performance of Pentium Anniversary Edition parts. I wonder whether they removed the two-thread lock, and, especially if hacks are still required, whether it is playable anyway.
That is, in a month and a half.

At its suite at CES this year, AMD was showing off a couple of new technologies. First, we got to see the upcoming Polaris GPU architecture in action running Star Wars Battlefront with some power meters hooked up. This is a similar demo to what I saw in Sonoma back in December, and it compares an upcoming Polaris GPU against the NVIDIA GTX 950. The result: total system power of just 86 watts on the AMD GPU and over 150 watts on the NVIDIA GPU.
Another new development from AMD on the FreeSync side of things was HDMI integration. The company took time at CES to showcase a pair of new HDMI-enabled monitors working with FreeSync variable refresh rate technology.

Quick post about something that came to light over at Phoronix. Someone noticed that Intel published a handful of PCI device IDs for graphics processors to Mesa and libdrm. It will take a few months for graphics drivers to catch up, although this suggests that Kaby Lake will be releasing relatively soon.
It also gives us hints about what Kaby Lake will be. Of the published batch, there will be six tiers of performance: GT1 has five IDs, GT1.5 has three IDs, GT2 has six IDs, GT2F has one ID, GT3 has three IDs, and GT4 has four IDs. Adding them up, we see that Intel plans 22 GPU devices. The Phoronix post lists what those device IDs are, but that is probably not interesting for our readers. Whether some of those devices overlap in performance or numbering is unclear, but it would make sense given how few SKUs Intel usually provides. I have zero experience in GPU driver development.
