A powerful architecture
In March of this year, NVIDIA announced the GeForce GTX Titan Z at its GPU Technology Conference. It was touted as the world's fastest graphics card with its pair of full GK110 GPUs but it came with an equally stunning price of $2999. NVIDIA claimed it would be available by the end of April for gamers and CUDA developers to purchase but it was pushed back slightly and released at the very end of May, going on sale for the promised price of $2999.
The specifications of GTX Titan Z are damned impressive - 5,760 CUDA cores, 12GB of total graphics memory, 8.1 TFLOPs of peak compute performance. But something happened between the announcement and product release that perhaps NVIDIA hadn't accounted for. AMD's Radeon R9 295X2, a dual-GPU card with full-speed Hawaii chips on-board, was released at $1499. I think it's fair to say that AMD took some chances that NVIDIA was surprised to see them take, including going the route of a self-contained water cooler and blowing past the PCI Express recommended power limits to offer a ~500 watt graphics card. The R9 295X2 was damned fast and I think it caught NVIDIA a bit off-guard.
As a result, the GeForce GTX Titan Z release was a bit quieter than most of us expected. Yes, the Titan Black card was released without sampling the gaming media but that was nearly a mirror of the GeForce GTX 780 Ti, just with a larger frame buffer and the performance of that GPU was well known. For NVIDIA to release a flagship dual-GPU graphics cards, admittedly the most expensive one I have ever seen with the GeForce brand on it, and NOT send out samples, was telling.
NVIDIA is adamant though that the primary target of the Titan Z is not just gamers but the CUDA developer that needs the most performance possible in as small of a space as possible. For that specific user, one that doesn't quite have the income to invest in a lot of Tesla hardware but wants to be able to develop and use CUDA applications with a significant amount of horsepower, the Titan Z fits the bill perfectly.
Still, the company was touting the Titan Z as "offering supercomputer class performance to enthusiast gamers" and telling gamers in launch videos that the Titan Z is the "fastest graphics card ever built" and that it was "built for gamers." So, interest peaked, we decided to review the GeForce GTX Titan Z.
The GeForce GTX TITAN Z Graphics Card
Cost and performance not withstanding, the GeForce GTX Titan Z is an absolutely stunning looking graphics card. The industrial design started with the GeForce GTX 690 (the last dual-GPU card NVIDIA released) and continued with the GTX 780 and Titan family, lives on with the Titan Z.
The all metal finish looks good and stands up to abuse, keeping that PCB straight even with the heft of the heatsink. There is only a single fan on the Titan Z, center mounted, with a large heatsink covering both GPUs on opposite sides. The GeForce logo up top illuminates, as we have seen on all similar designs, which adds a nice touch.

[H]ard|OCP has just posted a review of MSI's factory overclocked
HD7950 R9 280 GAMING OC card, with a 67MHz overclock on the GPU out of the box bringing it up to the 280X's default speed of 1GHz. With a bit of work that can be increased, [H]'s testing was also done at 1095MHz with the RAM raised to 5.4GHz which was enough to take it's performance just beyond the stock GTX 760 it was pitted against. Considering the equality of the performance as well as the price of these cards the decision as to which to go can be based on bundled games or personal preference.
"Priced at roughly $260 we have the MSI R9 280 GAMING OC video card, which features pre-overclocked performance, MSI's Twin Frozr IV cooling system, and highest end components. We'll focus on performance when gaming at 1080p between this boss and the GeForce GTX 760 video card!"

With the GPU landscape mostly settled for 2014, we have the ability to really dig in and evaluate the retail models that continue to pop up from NVIDIA and AMD board partners. One of our favorite series of graphics cards over the years comes from MSI in the form of the Lightning brand. These cards tend to take the engineering levels to a point other designers simply won't do - and we love it! Obviously the target of this capability is additional overclocking headroom and stability, but what if the GPU target has issues scaling already?
That is more or less the premise of the Radeon R9 290X Lightning from MSI. AMD's Radeon R9 290X Hawaii GPU is definitely a hot and power hungry part and that caused quite a few issues at the initial release. Since then though, both AMD and its add-in card partners have worked to improve the coolers installed on these cards to improve performance reliability and decrease the LOUD NOISES produced by the stock, reference cooler.
Let's dive into the latest to hit our test bench, the MSI Radeon R9 290X Lightning.
The MSI Radeon R9 290X Lightning
MSI continues to utilize the yellow and black color scheme that many of the company's high end parts integrate and I love the combination. I know that both NVIDIA and AMD disapprove of the distinct lack of "green" and "red" in the cooler and box designs, but good on MSI for sticking to its own thing.
The box for the Lightning card is equal to the prominence of the card itself and you even get a nifty drawer for all of the included accessories.
We originally spotted the MSI R9 290X Lightning at CES in January and the design remains the same. The cooler is quite large (and damn heavy) and is cooled by a set of three fans. The yellow fan in the center is smaller and spins a bit faster, creating more noise than I would prefer. All fan speeds can be adjusted with MSI's included fan control software.

AMD FreeSync is likely a technology or brand or term that is going to be used a lot between now and the end of 2014. When NVIDIA introduced variable refresh rate monitor technology to the world in October of last year, one of the immediate topics of conversation was the response that AMD was going to have. NVIDIA's G-Sync technology is limited to NVIDIA graphics cards and only a few (actually just one still as I write this) monitors actually have the specialized hardware to support it. In practice though, variable refresh rate monitors fundamentally change the gaming experience for the better.
At CES, AMD went on the offensive and started showing press a hacked up demo of what they called "FreeSync", a similar version of the variable refresh technology working on a laptop. At the time, the notebook was a requirement of the demo because of the way AMD's implementation worked. Mobile displays have previously included variable refresh technologies in order to save power and battery life. AMD found that it could repurpose that technology to emulate the effects that NVIDIA G-Sync creates - a significantly smoother gaming experience without the side effects of Vsync.
Our video preview of NVIDIA G-Sync Technology
Since that January preview, things have progressed for the "FreeSync" technology. Taking the idea to the VESA board responsible for the DisplayPort standard, in April we found out that VESA had adopted the technology and officially and called it Adaptive Sync.
So now what? AMD is at Computex and of course is taking the opportunity to demonstrate a "FreeSync" monitor with the DisplayPort 1.2a Adaptive Sync feature at work. Though they aren't talking about what monitor it is or who the manufacturer is, the demo is up and running and functions with frame rates wavering between 40 FPS and 60 FPS - the most crucial range of frame rates that can adversely affect gaming experiences. AMD has a windmill demo running on the system, perfectly suited to showing Vsync enabled (stuttering) and Vsync disabled (tearing) issues with a constantly rotating object. It is very similar to the NVIDIA clock demo used to show off G-Sync.
The demo system is powered by an AMD FX-8350 processor and Radeon R9 290X graphics card. The monitor is running at 2560x1440 and is the very first working prototype of the new standard. Even more interesting, this is a pre-existing display that has had its firmware updated to support Adaptive Sync. That's potentially exciting news! Monitors COULD BE UPGRADED to support this feature, but AMD warns us: "...this does not guarantee that firmware alone can enable the feature, it does reveal that some scalar/LCD combinations are already sufficiently advanced that they can support some degree of DRR (dynamic refresh rate) and the full DPAS (DisplayPort Adaptive Sync) specification through software changes."
The time frame for retail available monitors using DP 1.2a is up in the air but AMD has told us that the end of 2014 is entirely reasonable. Based on the painfully slow release of G-Sync monitors into the market, AMD has less of a time hole to dig out of than we originally thought, which is good. What is not good news though is that this feature isn't going to be supported on the full range of AMD Radeon graphics cards. Only the Radeon R9 290/290X and R7 260/260X (and the R9 295X2 of course) will actually be able to support the "FreeSync" technology. Compare that to NVIDIA's G-Sync: it is supported by NVIDIA's entire GTX 700 and GTX 600 series of cards.
All that aside, seeing the first official prototype of "FreeSync" is awesome and is getting me pretty damn excited about the variable refresh rate technologies once again! Hopefully we'll get some more hands on time (eyes on, whatever) with a panel in the near future to really see how it compares to the experience that NVIDIA G-Sync provides. There is still the chance that the technologies are not directly comparable and some in-depth testing will be required to validate.

Tagged: Intel, amd, richard huddy
Interesting news is crossing the ocean today as we learn that Richard Huddy, who has previously had stints at NVIDIA, ATI, AMD and most recently, Intel, is teaming up with AMD once again. Richard brings with him years of experience and innovation in the world of developer relations and graphics technology. Often called "the Godfather" of DirectX, AMD wants to prove to the community it is taking PC gaming seriously.
The official statement from AMD follows:
AMD is proud to announce the return of the well-respected authority in gaming, Richard Huddy. After three years away from AMD, Richard returns as AMD's Gaming Scientist in the Office of the CTO - he'll be serving as a senior advisor to key technology executives, like Mark Papermaster, Raja Koduri and Joe Macri. AMD is extremely excited to have such an industry visionary back. Having spent his professional career with companies like NVIDIA, Intel and ATI, and having led the worldwide ISV engineering team for over six years at AMD, Mr. Huddy has a truly unique perspective on the PC and Gaming industries.
Mr. Huddy rejoins AMD after a brief stint at Intel, where he had a major impact on their graphics roadmap. During his career Richard has made enormous contributions to the industry, including the development of DirectX and a wide range of visual effects technologies. Mr. Huddy’s contributions in gaming have been so significant that he was immortalized as ‘The Scientist’ in Max Payne (if you’re a gamer, you’ll see the resemblance immediately).
Kitguru has a video from Richard Huddy explaining his reasoning for the move back to AMD.
This move points AMD in a very interesting direction going forward. The creation of the Mantle API and the debate around AMD's developer relations programs are going to be hot topics as we move into the summer and I am curious how quickly Huddy thinks he can have an impact.
I have it on good authority we will find out very soon.

The latest installment in the ASUS ARES series of ultra-powerful, limited-edition graphics cards has been announced, and the Ares III is set to be the “world’s fastest” video card.
The dual-GPU powerhouse is driven by two “hand-selected” Radeon Hawaii XT GPUs (R9 290X cores) with 8GB of GDDR5 memory. The card is overclockable according to ASUS, and will likely arrive factory overclocked as they claim it will be faster out of the box than the reference R9-295x2. The ARES III features a custom-designed EK water block, so unlike the R9 295x2 the end user will need to supply the liquid cooling loop.
ASUS claims that the ARES III will “deliver 25% cooler performance than reference R9 295X designs“, but to achieve this ASUS “highly” recommends a high flow rate loop with at least a 120x3 radiator “to extract maximum performance from the card,” and they “will provide a recommended list of water cooling systems at launch”.
Only 500 of the ARES III will be made, and are individually numbered. No pricing has been announced, but ASUS says to expect it to be more than a 295x2 ($1499) - but less than a TITAN Z ($2999). The ASUS ROG ARES III will be available in Q3 2014.

Tagged: nvidia, geforce, geforce experience, ShadowPlay
NVIDIA has just launched another version of their GeForce Experience, incrementing the version to 2.1. This release allows video of up to "2500x1600", which I assume means 2560x1600, as well as better audio-video synchronization in Adobe Premiere. Also, because why stop going after FRAPS once you start, it also adds an in-game framerate indicator. It also adds push-to-talk for recording the microphone.
Another note: when GeForce Experience 2.0 launched, it introduced streaming of the user's desktop. This allowed recording of OpenGL and windowed-mode games by simply capturing an entire monitor. This mode was not capable of "Shadow Mode", which I believed was because they thought users didn't want a constant rolling video to be taken of their desktop in the event that they wanted to save a few minutes of it at some point. Turns out that I was wrong; the feature was coming and it arrived with GeForce Experience 2.1.
GeForce Experience 2.1 is now available at NVIDIA's website, unless it already popped up a notification for you.

The AMD Argument
Earlier this week, a story was posted in a Forbes.com blog that dove into the idea of NVIDIA GameWorks and how it was doing a disservice not just on the latest Ubisoft title Watch_Dogs but on PC gamers in general. Using quotes from AMD directly, the author claims that NVIDIA is actively engaging in methods to prevent game developers from optimizing games for AMD graphics hardware. This is an incredibly bold statement and one that I hope AMD is not making lightly. Here is a quote from the story:
Gameworks represents a clear and present threat to gamers by deliberately crippling performance on AMD products (40% of the market) to widen the margin in favor of NVIDIA products. . . . Participation in the Gameworks program often precludes the developer from accepting AMD suggestions that would improve performance directly in the game code—the most desirable form of optimization.
The example cited on the Forbes story is the recently released Watch_Dogs title, which appears to show favoritism towards NVIDIA GPUs with performance of the GTX 770 ($369) coming close the performance of a Radeon R9 290X ($549).
It's evident that Watch Dogs is optimized for Nvidia hardware but it's staggering just how un-optimized it is on AMD hardware.
Watch_Dogs is the latest GameWorks title released this week.
I decided to get in touch with AMD directly to see exactly what stance the company was attempting to take with these kinds of claims. No surprise, AMD was just as forward with me as they appeared to be in the Forbes story originally.
The AMD Stance
Central to AMD’s latest annoyance with the competition is the NVIDIA GameWorks program. First unveiled last October during a press event in Montreal, GameWorks combines several NVIDIA built engine functions into libraries that can be utilized and accessed by game developers to build advanced features into games. NVIDIA’s website claims that GameWorks is “easy to integrate into games” while also including tutorials and tools to help quickly generate content with the software set. Included in the GameWorks suite are tools like VisualFX which offers rendering solutions like HBAO+, TXAA, Depth of Field, FaceWorks, HairWorks and more. Physics tools include the obvious like PhysX while also adding clothing, destruction, particles and more.

Tagged: benchmarking, 3dmark
HELSINKI, FINLAND – May 28, 2014 – Futuremark today announced 3DMark Sky Diver, a new DirectX 11 benchmark test for gaming laptops and mid-range PCs. 3DMark Sky Diver is the ideal test for benchmarking systems with mainstream DirectX 11 graphics cards, mobile GPUs, or integrated graphics. A preview trailer for the new benchmark shows a wingsuited woman skydiving into a mysterious, uncharted location. The scene is brought to life with tessellation, particles and advanced post-processing effects. Sky Diver will be shown in full at Computex from June 3-7, or find out more on the Futuremark website.
Jukka Mäkinen, Futuremark CEO said, "Some people think that 3DMark is only for high-end hardware and extreme overclocking. Yet millions of PC gamers rely on 3DMark to choose systems that best balance performance, efficiency and affordability. 3DMark Sky Diver complements our other tests by providing the ideal benchmark for gaming laptops and mainstream PCs."
3DMark - The Gamer's Benchmark for all your hardware
3DMark is the only benchmark that offers a range of tests for different classes of hardware:
- Fire Strike, for high performance gaming PCs (DirectX 11, feature level 11)
- Sky Diver, for gaming laptops and mid-range PCs (DirectX 11, feature level 11)
- Cloud Gate, for notebooks and typical home PCs (DirectX 11 feature level 10)
- Ice Storm, for tablets and entry level PCs (DirectX 11 feature level 9)
With 3DMark, you can benchmark the full performance range of modern DirectX 11 graphics hardware. Where Fire Strike is like a modern game on ultra high settings, Sky Diver is closer to a DirectX 11 game played on normal settings. This makes Sky Diver the best choice for benchmarking entry level to mid-range systems and Fire Strike the perfect benchmark for high performance gaming PCs.
See 3DMark Sky Diver in full at Computex
3DMark Sky Diver will be on display on the ASUS, MSI, GIGABYTE, Galaxy, Inno3D, and G-Skill booths at Computex, June 3-7.
