ATI Radeon HD 2900 XT Benchmarks
BENCHMARKS AND CONCLUSIONS
Okay, enough jawbonin’ about specs and features. Let’s get to the question on everyone’s mind: Just how fast is the ATI Radeon HD 2900 XT. The core on the evaluation sample we were provided was clocked at 743MHz, while its 512MB of GDDR3 memory was set to run at 828MHz. We tested it in an Intel 975XBX2 motherboard with a Core 2 Extreme X6800 running at 2.93GHz and 2GB of DDR2 RAM.
That and the 2900 XT’s 320 stream processors delivered Quake 4 at a healthy 76.1 frames per second in Ultra Quality mode—nearly three frames per second faster than a stock-clocked 8800 GTS could manage running in the less-demanding High Quality mode. That’s impressive performance compared to a stock-clocked 640MB 8800 GTS, which delivered Quake 4 at just 65.4fps in Ultra Quality. And when we dropped the 2900 XT to that level, its numbers catapulted to 84.7fps.Our FEAR benchmark results were also notable, with the card pumping out 63fps compared to the 8800 GTS’s measly 52fps.
AMD is hoping to get a lot of mileage out of the fact that cards based on their best GPU will not only retail for just $400 (we found boards from PowerColor and Sapphire selling for $410 each today), but that each card will also come bundled with three brand-new Valve games: Half-Life 2: Episode 2, Team Fortress 2, and Portal. Bundling brand-new games is a good move on AMD’s part, but it doesn’t change the fact that cards based on GeForce 8800 GTS with 640MB frame buffers were selling for an average on $332 (not including mail-in rebates ranging from $20 to $30) on the day of AMD’s announcement.
It also doesn’t change the fact that the GeForce 8800 XTX leaves AMD’s part in the dust in terms of gaming performance—and at an average price premium of just $111. And then there’s the 8800 Ultra and the whole matter of CrossFire to consider. Intel’s 975 BX2 boards support CrossFire today; but now that AMD owns ATI, who knows how much longer Intel will want to support its primary competitor’s technology.
The 2900 XT looks a lot better when you eliminate all consideration of dual videocards in your rig. It’s certainly a better solution for delivering both high-def video and solid gaming performance than anything Nvidia currently has to offer. But when you consider how little penetration the next-gen optical-drive formats have managed to achieve, I don’t know that it will be enough to generate the sales volume AMD needs.
