With leading-edge graphics cards getting more and more dedicated RAM shoved onto their PCBs, it's only surprising that it has taken this long for a 1GB single GPU card to hit the market. Diamond Multimedia has just announced the launch of its Radeon HD 2900 XT 1GB, which packs a full gigabyte of GDDR4 memory, second-generation unified shader architecture, 512-bit memory interface, integrated CrossFire scalability, and built-in HDMI support. Moreover, it also includes ATI's Avivo display technology, dual-link DVI output, HDCP compliance, and DirectX 10 support. No word just yet on what kind of premium you'll be expected to pay for this momentary claim of superiority, but we'd wait for the benchmarks to see if it's even worth the extra coin.

Although preliminary testing proved that ATI's R600 architecture wasn't messing around, DailyTech added another layer of proof to the pudding as it benchmarked a bonafide Radeon HD 2900 XT against NVIDIA's 640MB GeForce 8800 GTS. The DirectX 10-capable card is a notch above the HD 2600 XT that was snapped in the wild, and the tested unit featured 320 stream processors, 512MB of GDDR3 RAM, a dual-slot "blower-type heat sink," dual dual-link DVI ports, and a serious desire to crank out impressive FPS numbers. While the marks weren't the end-all answer to the ATI vs. NVIDIA question, the Radeon managed to best its opponent in every single trial, including Call of Duty 2, Company of Heroes, F.E.A.R., Oblivion, 3DMark06, Maya 02, Cadalyst C2006, and a few more for good measure. Of course, we're sure NVIDIA will be hitting back with something of its own, but feel free to hit the read link if you take pleasure in graphical beat downs with ATI escaping victorious.
