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.

I have never seen pre-release benchmarks that were not faked. I am assuming these are.
I don’t think its true, but if it is that some sick performance. braking past the 200G/sec badwith is some serious performance per GPU. hopefully their new drivers lets crossfire scale better then they do now. Nvidia is raping them with even 2 gtx 460’s in sli ( cheaper and performs better vs. HD 5850s and even in some cases 5870s in crossfire)
rumors have it that a dual 6970 is to follow the 6870 after a few weeks/month(s) like last year tape out.
