Well, according to John Peddie Research (JPR), not too good if you are Matrox or S3. The total market for add-in boards decreased 5.4% from last quarter. 14.0 million were shipped across the entire industry. Neither company accounted for a thousandth of that value leaving them with a maximum 7000 units shipped, best case scenario. This industry is, basically, a two horse race.
|This Quarter||Prev. Quarter||Last Year|
Two horses unless you count the Intel Xeon Phi. While technically not a graphics processor despite hardware design, 48,000 of these coprocessors were sold, already, for the Tianhe-2 supercomputer. This is at least seven-fold more than an entire quarter for Matrox. Unfortunately JPR does not report on Intel add-in cards despite its overlap with the GPU add-in market. These numbers could get even more interesting as years progress.
As for the two big players, AMD and NVIDIA, both hold very dominant positions. Almost spiting the 750,000 unit industry decline, AMD experienced a total increase of 0.8% quarter-over-quarter. Their market share gained 2.3% as a result of this growth. NVIDIA experienced a total decrease of 8.9%.
In all, AMD has been doing better than the industry average. They are fighting the slight decline in the graphics industry while simultaneously helping GPUs hold off against larger declines in PC systems.

Despite a slight decline in PC sales compared to last quarter, graphics processors are on the rise. Jon Peddie Research attributes the heightened interest in graphics, with a decline in systems, to a trend towards multiple GPUs in a system. Crossfire and SLI, according to the report, are not driving this drift but they are relevant. More importantly, consumers are adding discrete graphics to systems with integrated solutions.
AMD has experienced an increase in shipments of 47% for laptop APUs. Desktop heterogeneous processors declined but, in all, shipments increased 11%. Intel, likewise, saw an increase albeit just 6%. NVIDIA declined 8%. AMD now enjoys a 5.8% lead in total market share over NVIDIA.
Many PCs have access to multiple graphics processors simultaneously. With an increase of available GPUs, software developers might take the plunge into fully supporting heterogeneous architectures. You could imagine a game which offloads physics or AI pathfinding to secondary graphics. Sure, the increased heat would slightly limit the turbo-performance of the CPU, but the increased parallel performance should overtake that decreased serial performance for a sensible developer.
JPR claims an average of nearly 1.4 GPUs available per system.
The increased laptop heterogeneous processors is a major win for AMD. Still, I wonder how much Never Settle played in to users dropping discrete graphics into machines which would otherwise have integrated (chipset or processor) graphics. The discrete graphics market has declined and yet somehow AMD got a boost from double-attach or replaced graphics.
The report only discusses consumer x86 tablets, desktops, laptops, and some hybrid between the previous three categories. Other processor architectures or x86 servers are not covered.

Trust the cloud... be the cloud.
The executives on stage might as well have waved their hands while reciting that incantation during the announcement of the Xbox One. Why not? The audience would have just assumed Don Mattrick was trying to get some weird Kinect achievement on stage. You know, kill four people with one laser beam while trying to sink your next-generation platform in a ranked keynote. 50 Gamerscore!
Microsoft stated, during and after the keynote, that each Xbox One would have access to cloud servers for certain processing tasks. Xbox Live would be receiving enough servers such that each console could access three times its performance, at launch, to do... stuff. You know, things that are hard to calculate but are not too dependent upon latency. You know what we mean, right?
Apparently Microsoft did not realize that was a detail they were supposed to sell us on.
In the mean time, NVIDIA has been selling us on offloaded computation to cloud architectures. We knew Global Illumination (GI) was a very complicated problem. Most of the last couple decades has been progressively removing approximations to what light truly does.
CloudLight is their research project, presented at SIGRAPH Asia and via Williams College, to demonstrate server-processed indirect lighting. In their video, each of the three effects are demonstrated at multiple latencies. The results look pretty good until about 500ms which is where the brightest points are noticeably in the wrong locations.
The three methods used to generate indirect lighting are: irradiance maps, where lightmaps are continuously calculated on a server and streamed by H.264; photons, which raytraces lighting for the scene as previous rays expire and streams only the most current ones to clients who need it; and voxels, which stream fully computed frames to the clients. The most interesting part is that as you add more users, in most cases, server-processing remains fairly constant.
It should be noted, however, that each of these demonstrations only moved the most intense lights slowly. I would expect an effect such as switching a light on in an otherwise dark room would create a "pop-in" effect if it lags too far behind user interaction or the instantaneous dynamic lights.
That said, for a finite number of instant switches, it would be possible for a server to render both results and have the client choose the appropriate lightmap (or the appropriate set of pixels from the same, large, lightmap). For an Unreal Tournament 3 mod, I was experimenting with using a Global Illumination solver to calculate lighting. My intention was to allow users to turn on and off a handful of lights in each team's base. As lights were shot out or activated by a switch, the shader would switch to the appropriate pre-rendered solution. I would expect a similar method to work here.
What other effects do you believe can withstand a few hundred milliseconds of latency?

Scott Wasson from The Tech Report and Ryan have been discussing the microstuttering present in Crossfire and while Ryan got his hands on the hardware to capture the raw output first, The Tech Report have been investigating this issue as in depth as Ryan and Ken have been. Their look at the new Catalyst and the effects of Frame Pacing show the same results as you saw yesterday in Ryan's article; for essentially no cost in performance you can get a much smoother experience when using a CrossFire system on a single display. In their article they have done a great job of splicing together videos of runthroughs of several games with the Frame Pacing disabled on one side and enabled on the other, allowing you to see with your own eyes the difference in game play, without having to have your own Crossfire system.
"Can a driver fix what ails the Radeon HD 7990? Will the new Catalysts magically transform this baby into the fastest graphics card on the planet? We go inside the second to find out."

NVIDIA recently released a new set of beta GeForce graphics card drivers targetted at the 400, 500, 600, and 700 series GPUs. The new version 326.41 beta drivers feature the same performance tweaks as the previous 326.19 drivers while baking in beta support for PC game streaming to NVIDIA’s Shield gaming portable from a compatible GeForce graphics card (GTX 650 or better). The new beta release is also the suggested version to use for those running the Windows 8.1 Preview.
NVIDIA has included the same performance tweaks as version 326.19. The tweaks offer up to 19% performance increases, depending on the particular GPU setup. For example, users running a GTX 770 will see as much as 15% better performance in Dirt: Showdown and 6% in Tomb Raider. Performance improvements are even higher for GTX 770 SLI setups, with boosts in Dirt: Showdown and F1 2012 of 19% and 11% respectively. NVIDIA has also added SLI profiles for Splinter Cell: Blacklist and Batman: Arkham Origins.
The NVIDIA Shield launched recently and reviews are making the rounds around the Internet. One of the exciting features of the Shield gaming handheld is the ability to stream PC games from a PC with NVIDIA graphics card to the Shield over Wi-Fi.
The 326.41 drivers improve performance across several games on the GTX 770.
The other major changes are improvements to tiled 4K displays, which are displays with 4K resolutions that are essentially made of two separate displays, and the monitor even shows up to the OS as two separate displays despite being in a single physical monitor. Using DisplayPort MST and tiled displays allows monitor manufacturers to deliver 4K displays with higher refresh rates.
Interested GeForce users can grab the latest beta drivers from the NVIDIA website or via the links below:
Frame Pacing for CrossFire
When the Radeon HD 7990 launched in April of this year, we had some not-so-great things to say about it. The HD 7990 depends on CrossFire technology to function and we had found quite a few problems with AMD's CrossFire technology over the last months of testing with our Frame Rating technology, the HD 7990 "had a hard time justifying its $1000 price tag." Right at launch, AMD gave us a taste of a new driver that they were hoping would fix the frame pacing and frame time variance issues seen in CrossFire, and it looked positive. The problem was that the driver wouldn't be available until summer.
As I said then: "But until that driver is perfected, is bug free and is presented to buyers as a made-for-primetime solution, I just cannot recommend an investment this large on the Radeon HD 7990."
Today could be a very big day for AMD - the release of the promised driver update that enables frame pacing on AMD 7000-series CrossFire configurations including the Radeon HD 7990 graphics cards with a pair of Tahiti GPUs.
It's not perfect yet and there are some things to keep an eye on. For example, this fix will not address Eyefinity configurations which includes multi-panel solutions and the new 4K 60 Hz displays that require a tiled display configuration. Also, we found some issues with more than two GPU CrossFire that we'll address in a later page too.
New Driver Details
Starting with 13.8 and moving forward, AMD plans to have the frame pacing fix integrated into all future drivers. The software team has implemented a software based frame pacing algorithm that simply monitors the time it takes for each GPU to render a frame, how long a frame is displayed on the screen and inserts delays into the present calls when necessary to prevent very tightly timed frame renders. This balances or "paces" the frame output to the screen without lowering the overall frame rate. The driver monitors this constantly in real-time and minor changes are made on a regular basis to keep the GPUs in check.
As you would expect, this algorithm is completely game engine independent and the games should be completely oblivious to all that is going on (other than the feedback from present calls, etc).
This fix is generic meaning it is not tied to any specific game and doesn't require profiles like CrossFire can from time to time. The current implementation will work with DX10 and DX11 based titles only with DX9 support being added later with another release. AMD claims this was simply a development time issue and since most modern GPU-bound titles are DX10/11 based they focused on that area first. In phase 2 of the frame pacing implementation AMD will add in DX9 and OpenGL support. AMD wouldn't give me a timeline for implementation though so we'll have to see how much pressure AMD continues with internally to get the job done.
