If you've been keeping track of unofficial stories about AMD's Northern Islands GPUs, you'll know the Radeon HD 6800 series is but the tip of the iceberg. A higher-end "Cayman" GPU is on the way, as well. The folks at ZOL.com.cn have posted images and performance numbers for the Cayman-based Radeon HD 6970, and it looks quite potent indeed.
ZOL's numbers cover both 3DMark Vantage and the Unigine Heaven benchmark, comparing the new card to two existing products: the Radeon HD 5870 and GeForce GTX 480. I've compiled the data into a handy table for easy perusal:
|Card||3DMark Vantage||Unigine Heaven|
|Radeon HD 6970||P24499||36.6 FPS|
|GeForce GTX 480||P21106||29.5 FPS|
|Radeon HD 5870||P19337||17.3 FPS|
If there's any truth at all to these numbers, AMD might once again end up with the quickest single GPU on the market. That status could be short-lived, of course—we've also been hearing reports about the imminent arrival of a GeForce GTX 580 from the Nvidia camp. (Thanks to TweakTown for the tip.)
