A very early look at the future of Catalyst

Today is a very interesting day for AMD.  It marks both the release of the reference design of the Radeon HD 7990 graphics card, a dual-GPU Tahiti behemoth, and the first sample of a change to the CrossFire technology that will improve animation performance across the board.  Both stories are incredibly interesting and as it turns out both feed off of each other in a very important way: the HD 7990 depends on CrossFire and CrossFire depends on this driver. 

If you already read our review (or any review that is using the FCAT / frame capture system) of the Radeon HD 7990, you likely came away somewhat unimpressed.  The combination of a two AMD Tahiti GPUs on a single PCB with 6GB of frame buffer SHOULD have been an incredibly exciting release for us and would likely have become the single fastest graphics card on the planet.  That didn't happen though and our results clearly state why that is the case: AMD CrossFire technology has some serious issues with animation smoothness, runt frames and giving users what they are promised. 

Our first results using our Frame Rating performance analysis method were shown during the release of the NVIDIA GeForce GTX Titan card in February.  Since then we have been in constant talks with the folks at AMD to figure out what was wrong, how they could fix it, and what it would mean to gamers to implement frame metering technology.  We followed that story up with several more that showed the current state of performance on the GPU market using Frame Rating that painted CrossFire in a very negative light.  Even though we were accused by some outlets of being biased or that AMD wasn't doing anything incorrectly, we stuck by our results and as it turns out, so does AMD. 

Today's preview of a very early prototype driver shows that the company is serious about fixing the problems we discovered. 

If you are just catching up on the story, you really need some background information.  The best place to start is our article published in late March that goes into detail about how game engines work, how our completely new testing methods work and the problems with AMD CrossFire technology very specifically.  From that piece:

It will become painfully apparent as we dive through the benchmark results on the following pages, but I feel that addressing the issues that CrossFire and Eyefinity are creating up front will make the results easier to understand.  We showed you for the first time in Frame Rating Part 3, AMD CrossFire configurations have a tendency to produce a lot of runt frames, and in many cases nearly perfectly in an alternating pattern.  Not only does this mean that frame time variance will be high, but it also tells me that the value of performance gained by of adding a second GPU is completely useless in this case.  Obviously the story would become then, “In Battlefield 3, does it even make sense to use a CrossFire configuration?”  My answer based on the below graph would be no.

An example of a runt frame in a CrossFire configuration

NVIDIA's solution for getting around this potential problem with SLI was to integrate frame metering, a technology that balances frame presentation to the user and to the game engine in a way that enabled smoother, more consistent frame times and thus smoother animations on the screen.  For GeForce cards, frame metering began as a software solution but was actually integrated as a hardware function on the Fermi design, taking some load off of the driver.

Missed the live event?  Here is the full replay feature me and Tom Petersen!

Hopefully by now you have read our review of the NVIDIA GeForce GTX TITAN 6GB graphics card that was just released.  This is definitely a product release that highlights a generations of GPUs and I would really encourage you to read the article and offer your feedback.

However, we have another event to promote right now: NVIDIA's Tom Petersen will be joining me on PCPer Live! at 11am PT / 2pm ET to talk about the GeForce GTX TITAN and its performance, features, pricing and more!

Before getting into the performance of the $1000 NVIDIA TITAN it is worth looking at the improvements NVIDIA has added to this GK110 beast.  At 10.5" long it is a half inch longer than a 680 and a full 1.5" shorter than a 690, which allows it to fit in a wider variety of cases and the vastly improved thermals allow the usage of much smaller cases than other high end GPUs can manage without exotic cooling solutions.  There is also a reduction in noise generated, to the point where SLI'd TITANs run quieter than some single card solutions, not to mention much faster.  To take a look at just how much faster you can see [H]ard|OCP's results which you can compare to Ryan's results.

H_TITAN.jpg

"NVIDIA is launching a TITAN today, literally, the new GeForce GTX TITAN video card is here, and we have a lot to talk about. We test single-GPU and 2-way SLI today, with more to follow later. We will find out if this TITAN of a video card really is worth it, and just who this video card is designed for. Be prepared to face the fastest single-GPU video card."

TITAN is back for more!

Our NVIDIA GeForce GTX TITAN Coverage Schedule:

If you are reading this today, chances are you were here on Tuesday when we first launched our NVIDIA GeForce GTX TITAN features and preview story (accessible from the link above) and were hoping to find benchmarks then.  You didn't, but you will now.  I am here to show you that the TITAN is indeed the single fastest GPU on the market and MAY be the best graphics cards (single or dual GPU) on the market depending on what usage models you have.  Some will argue, some will disagree, but we have an interesting argument to make about this $999 gaming beast.

A brief history of time...er, TITAN

In our previous article we talked all about TITAN's GK110-based GPU, the form factor, card design, GPU Boost 2.0 features and much more and I would highly press you all to read it before going forward.  If you just want the cliff notes, I am going to copy and paste some of the most important details below.

IMG_9502.JPG

From a pure specifications standpoint the GeForce GTX TITAN based on GK110 is a powerhouse.  While the full GPU sports a total of 15 SMX units, TITAN will have 14 of them enabled for a total of 2688 shaders and 224 texture units.  Clock speeds on TITAN are a bit lower than on GK104 with a base clock rate of 836 MHz and a Boost Clock of 876 MHz.  As we will show you later in this article though the GPU Boost technology has been updated and changed quite a bit from what we first saw with the GTX 680.

The bump in the memory bus width is also key, being able to feed that many CUDA cores definitely required a boost from 256-bit to 384-bit, a 50% increase.  Even better, the memory bus is still running at 6.0 GHz resulting in total memory bandwdith of 288.4 GB/s.

blockdiagram2.jpg

Speaking of memory - this card will ship with 6GB on-board.  Yes, 6 GeeBees!!  That is twice as much as AMD's Radeon HD 7970 and three times as much as NVIDIA's own GeForce GTX 680 card.  This is without a doubt a nod to the super-computing capabilities of the GPU and the GPGPU functionality that NVIDIA is enabling with the double precision aspects of GK110.

GK110 Makes Its Way to Gamers

Our NVIDIA GeForce GTX TITAN Coverage Schedule:

Back in May of 2012 NVIDIA released information on GK110, a new GPU that the company was targeting towards HPC (high performance computing) and the GPGPU markets that are eager for more processing power.  Almost immediately the questions began on when we might see the GK110 part make its way to consumers and gamers in addition to finding a home in supercomputers like Cray's Titan system capable of 17.59 Petaflops/s.

Nine months later we finally have an answer - the GeForce GTX TITAN is a consumer graphics card built around the GK110 GPU.  Comprised of 2,688 CUDA cores, 7.1 billion transistors and with a die size of 551 mm^2, the GTX TITAN is a big step forward (both in performance and physical size).
