While we're on the subject of next-gen, non-ATI-branded Radeon graphics cards, a Chinese website has obtained performance data for one of those still-unannounced products. PCinlife actually has two rounds of numbers purportedly obtained from an unspecified Radeon HD 6800-series GPU—and that thing looks to be quite the performer.
The numbers show 3DMark Vantage scores of X12092 and P24499, a Crysis benchmark frame rate of 43.55 FPS at 1920x1200 with "Very high" settings and 4X antialiasing, and a Unigine Heaven score of 922 with "extreme" tessellation.
VR-Zone went and put the data in perspective, and it claims the results are above what one can expect from Nvidia's GeForce GTX 480, not far from the dual-GPU Radeon HD 5970. For instance, VR-Zone quotes "typical" Unigine Heaven scores of 500 or more for the Radeon HD 5870 and 900 or more for the GTX 480, and the mystery 6800-series card hit 922. Since that benchmark makes very heavy use of tessellation, those results suggest AMD may have beefed up the triangle setup and geometry processing capabilities of the 6800 series substantially, as Nvidia did with its Fermi architecture.
Looks like Nvidia could be in hot water, especially if AMD has a whole lineup of next-gen Radeons up its sleeve, as last week's driver leak hints. Recent reports from the Far East point to November availability for at least some of those upcoming GPUs.
