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.

Intel Pushes Device IDs of Kaby Lake GPUs

Subject: Graphics Cards, Processors | January 8, 2016 - 07:38 AM |
Tagged: Intel, kaby lake, linux, mesa

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.

AMD Radeon Software Crimson Edition 16.1 Hotfix arrives

Subject: Graphics Cards | January 7, 2016 - 11:55 PM |
Tagged: crimson, amd

That's right ladies and germs, not even a full week into 2016 and AMD has a new driver for you, or at least a hotfix version of Crimson 16.1.  If you are playing Elite:Dangerous, Fallout 4 or Just Cause 3 there are a number of fixes to known issues from the original 12.1 which will make it worth picking up as soon as you can.  So far in testing, game profiles do seem to last through an update so if you did take advantage of the game specific overclocking settings you should not lose all your hard work.

They have also included fixes specific to VSR, odd HDMI setups and flickering in Freesync displays.  As always there are a few bugs still to be ironed out, which is why you should fill in the bug reporting tool at the bottom of the driver page instead of just throwing things at random passersby ... as fun and entertaining as that may be.

At just over $200, can the XFX R9 380X Double Dissipation XXX OC 4GB unseat a GTX 960?

Take a quick break from reading about the soon to be released technology at CES for a look at a GPU you can buy right now.  The XFX DD XXX series has been around for a few generations and the XFX R9 380X Double Dissipation XXX OC 4GB sports the same custom DD cooler you would expect.  The factory overclock is quite modest, 20MHz on the GPU taking it to 990MHz and retaining the default 5.7GHz memory clock.  Of course [H]ard|OCP were not going to leave that as is, they hit a 1040MHz core and 6.1GHz memory clock thanks to the custom cooling on the card, although with no way to adjust voltage they felt this card could be capable of more if that feature was added to the card.  Read on to see how this card compares against the ASUS STRIX GTX 960 DCU II OC in this ~$220 GPU showdown.

"On our test bench today is the XFX R9 380X Double Dissipation XXX OC 4GB video card. It features the latest Ghost Thermal 3.0 cooling technology from XFX and a factory overclock. We will compare it to the ASUS STRIX GTX 960 DCU II OC 4GB in a battle of the $229 price point video cards to determine the better overall value."

CES 2016: Rise of the Tomb Raider NVIDIA Bundle

Subject: Graphics Cards, Shows and Expos | January 7, 2016 - 07:03 PM |
Tagged: square enix, nvidia, CES 2016, CES

NVIDIA has just announced a new game bundle. If you purchase an NVIDIA GeForce GTX 970, GTX 980 desktop or mobile, GTX 980 Ti, GTX 980M, or GTX 970M, then you will receive a free copy of Rise of the Tomb Raider. As always, make sure the retailer is selling the participating card. If the product has a download code, it will be specially marked. NVIDIA will not upgrade non-participating stock to the bundle.

nvidia-2016-tombraider-glp-header.jpg

Rise of the Tomb Raider will go live on January 29th. It was originally released in November as an Xbox One timed exclusive. It will also arrive on the PlayStation 4, but not until “holiday,” which is probably around Q4 (or maybe late Q3).

If you purchase the bundle, then you graphics card will obviously be powerful enough to run the game. At a minimum, you will require a GeForce GTX 650 (2GB) or an AMD HD 7770 (2GB). The CPU needs are light too, requiring just a Sandy Bridge Core i3 (Intel Core i3-2100) or AMD's equivalent. Probably the only concern would be the minimum of 6GB system RAM, which also requires a 64-bit operating system. Now that the Xbox 360 and PlayStation 3 have been deprecated, 32-bit gaming will be increasingly rare for “AAA” titles. That said, we've been ramping up to 64-bit for the last decade. one of the first games that supported x86-64 was Unreal Tournament 2004.

The Rise of the Tomb Raider NVIDIA bundle starts today.

CES 2016: NVIDIA talks SHIELD Updates and VR-Ready Systems

Subject: Graphics Cards, Shows and Expos | January 6, 2016 - 02:39 AM |
Tagged: vr ready, VR, virtual reality, video, Oculus, nvidia, htc, geforce, CES 2016, CES

Other than the in-depth discussion from NVIDIA on the Drive PX 2 and its push into autonomous driving, NVIDIA didn't have much other news to report. We stopped by the suite and got a few updates on SHIELD and the company's VR Ready program to certify systems that meet minimum recommended specifications for a solid VR experience.

For the SHIELD,  NVIDIA is bringing Android 6.0 Marshmallow to the device, with new features like shared storage and the ability to customize the home screen of the Android TV interface. Nothing earth shattering and all of it is part of the 6.0 rollout. 

The VR Ready program from NVIDIA will validate notebooks, systems and graphics cards that have the amount of horsepower to meet the minimum performance levels for a good VR experience. At this point, the specs essentially match up with what Oculus has put forth: a GTX 970 or better on the desktop and a GTX 980 (full, not 980M) on mobile. 

Other than that, Ken and I took in some of the more recent VR demos including Epic's Bullet Train on the final Oculus Rift and Google's Tilt Brush on the latest iteration of the HTC Vive. Those were both incredibly impressive though the Everest demo that simulates a portion of the mountain climb was the one that really made me feel like I was somewhere else.

Check out the video above for more impressions!

CES 2016: ASUS Announces XG Station 2 External Graphics

Subject: Graphics Cards, Mobile, Shows and Expos | January 5, 2016 - 09:47 PM |
Tagged: external graphics, CES 2016, CES, asus

While external graphics has been a thing for quite some time, it was rarely an available thing. Several companies, such as AMD, Lucid, and others, announced products that were never sold. ASUS had their XG Station for Windows Vista that allowed laptops to plug into a GeForce 8600 GT, which was only available in Australia. Only now are we beginning to see options from Alienware, MSI, and even Microsoft that are widely available.

asus-2016-ROG XG2_front.jpg

ASUS is jumping back in, too. Not much is known about the XG Station 2, except that it is “specially designed for ASUS laptops and graphics cards.” This sounds like it is using a proprietary connector, similar to Alienware and MSI, to connect to ASUS laptops. Also saying it's specifically for ASUS graphics cards is a bit confusing, though. If it is an open PCIe slot, I'm not sure why or how it would be limited to ASUS cards. If the graphics cards are pre-installed, then we don't know the list of potential GPUs.

Either way, ASUS states that the dock can be disconnected without shutting down the PC. I'm interested to see how the GPU is supposed to be unplugged, as Alienware's option can only be done when the system is off, and Microsoft's Surface Book has a software detach with a hardware latch. The connector will also charge the laptop, which is an interesting add-in.

Pricing and availability varies, like the other ASUS announcements, by region.

AMD Polaris Architecture Coming Mid-2016

In early December, I was able to spend some time with members of the newly formed Radeon Technologies Group (RTG), which is a revitalized and compartmentalized section of AMD that is taking over all graphics work. During those meetings, I was able to learn quite a bit about the plans for RTG going forward, including changes for AMD FreeSync and implementation of HDR display technology, and their plans for the GPUOpen open-sourced game development platform.  Perhaps most intriguing of all: we received some information about the next-generation GPU architecture, targeted for 2016.

Codenamed Polaris, this new architecture will be the 4th generation of GCN (Graphics Core Next), and it will be the first AMD GPU that is built on FinFET process technology. These two changes combined promise to offer the biggest improvement in performance per watt, generation to generation, in AMD’s history.

polaris-5.jpg

Though the amount of information provided about the Polaris architecture is light, RTG does promise some changes to the 4th iteration of its GCN design. Those include primitive discard acceleration, an improved hardware scheduler, better pre-fetch, increased shader efficiency, and stronger memory compression. We have already discussed in a previous story that the new GPUs will include HDMI 2.0a and DisplayPort 1.3 display interfaces, which offer some impressive new features and bandwidth. From a multimedia perspective, Polaris will be the first GPU to include support for h.265 4K decode and encode acceleration.

polaris-15.jpg

This slide shows us quite a few changes, most of which were never discussed specifically that we can report, coming to Polaris. Geometry processing and the memory controller stand out as potentially interesting to me – AMD’s Fiji design continues to lag behind NVIDIA’s Maxwell in terms of tessellation performance and we would love to see that shift. I am also very curious to see how the memory controller is configured on the entire Polaris lineup of GPUs – we saw the introduction of HBM (high bandwidth memory) with the Fury line of cards.

Rumor: Polaris Is the next AMD Radeon Core Architecture

Subject: Graphics Cards | December 31, 2015 - 06:41 PM |

A report claims that Polaris will succeed GCN (Graphics Core Next) as the next AMD Radeon GPU core, which will power the 400-series graphics cards.

As these rumors go, this is about as convoluted as it gets. VideoCardz has published the story, sourced from WCCFtech, who was reporting on a post with supposedly leaked slides at HardwareBattle. The primary slide in question has since been pulled, and appears below:

Of course the name does nothing to provide architectural information on this presumptive GCN replacement, and a new core for the 400-series GPUs was expected anyway after the 300-series was largely a rebranded 200-series (that's a lot of series). Let's hope actual details emerge soon, but for now we can speculate on mysterious tweets from certain interested parties:

Tessellation Support Expands for Intel's Open Linux Driver

Subject: Graphics Cards | December 29, 2015 - 12:05 PM |
Tagged: opengl, mesa, linux, Intel

The open-source driver for Intel is known to be a little behind on Linux. Because Intel does not provide as much support as they should, the driver still does not support OpenGL 4.0, although that is changing. One large chunk of that API is support for tessellation, which comes from DirectX 11, and recent patches are adding it for supported hardware. Proprietary drivers exist, at least for some platforms, but they have their own issues.

intel-2015-linux-driver-mesa.png

According to the Phoronix article, once the driver succeeds in supporting OpenGL 4.0, it will not be too long to open the path to 4.2. Tessellation is a huge hurdle, partially because it involves adding two whole shading stages to the rendering pipeline. Broadwell GPUs were recently added, but a patch that was committed yesterday will expand that to Ivy Bridge and Haswell. On Windows, Intel is far ahead -- pushing OpenGL 4.4 for Skylake-based graphics, although that platform only has proprietary drivers. AMD and NVIDIA are up to OpenGL 4.5, which is the latest version.

While all of this is happening, Valve is working on an open-source Vulkan driver for Intel on Linux. This API will be released adjacent to OpenGL, and is built for high-performance graphics and compute. (Note that OpenCL is more sophisticated than Vulkan "1.0" will be on the compute side of things.) As nice as it would be to get high-end OpenGL support, especially for developers who want a more simplified structure to communicate to GPUs with, Vulkan will probably be the API that matters most for high-end video games. But again, that only applies to games that are developed for it.
