ATI 6870 3D MARK VANTAGE SCORES LEAKED

A forum member on Chinese website has leaked a 3D Mark Vantage Extreme benchmark, alongwith a GPU-Z screenshot, alleged to be from a next-gen ATI Radeon HD 6870. The important result is the 3D Mark Vantage score, which X11963. Considering the GTX 480 offers under X10000, and the HD 5870 is in the X9000 range, this is an impressive result for what is rumoured to be a minor intermediate generation on the same 40nm process.

It is the GPU-Z screenshot, however, which reveals more details. GPU-Z recognizes the sample as an "ATI Radeon HD 6800 Series". The GPU ID is 6718, which according to the Catalyst 10.8 codename list, indicates a Cayman XT GPU - well in line with rumours thus far. The core clock is same as the HD 5870 - 850 MHz. This suggests the performance boost comes from more functional units (perhaps 1920 SP) or improved performance per clock (using some of Northern Islands' units) or a combination of both. The GDDR5 speed is boosted by a whopping 33% to 1.6 GHz, or a whopping 6.4 GHz effective. The same 256-bit memory interface is retained, but the ultra fast memory results in a massive memory bandwidth of 204.8 GB/s - well over the GTX 480's 177.4 GB/s. Of course, one of the possibilities for such a high memory clock speed, as well as the impressive benchmark, could be that the card is benchmarked overclocked.

awsomness ....

yes topher bang ur head against the table

That's some fancy sh*t if its true.

more 6870 benchmarks !!!!
