Rumor: Alleged ATI Radeon HD 6870 3DMark Vantage Benchmark

Over at VRZone, they’ve dug up a screenshot of GPU-Z and 3DMark Vantage Extreme that claim to be showing the results of the ATI Radeon HD6870.  If it’s true, it’s a significant boost that puts it ahead of the NVidia GTX480 (which comes in under 10,000).

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.

Now, take this with a grain of salt as these could easily have been photoshopped.  However, most of the details make sense.
