AMD's Own HD 7970 Performance Expectations?
Ahead of every major GPU launch, both NVIDIA and AMD give out a document to reviewers known as Reviewer's Guide, in which both provide guidelines (suggestions, not instructions), to reviewers to ensure new GPUs are given a fair testing. In such documents, the two often also give out their own performance expectations from the GPUs they're launching, in which they compare the new GPUs to either previous-generation GPUs from their own brand, or from the competitors'. Apparently such a performance comparison between the upcoming Radeon HD 7970 and NVIDIA's GeForce GTX 580, probably part of such a document, got leaked to the internet, which 3DCenter.org re-posted. The first picture below, is a blurry screenshot of a graph in which the two GPUs are compared along a variety of tests, at a resolution of 2560 x 1600. A Tweakers.net community member recreated that graph in Excel, using that data (second picture below).
A couple of things here are worth noting. Reviewer guide performance numbers are almost always exaggerated, so if reviewers get performance results lower than 'normal', they find it abnormal, and re-test. It's an established practice both GPUs vendors follow. Next, AMD Radeon GPUs are traditionally good at 2560 x 1600. For that matter, the performance gap between even the Radeon HD 6970 and GeForce GTX 580 narrows a bit at that resolution.

OVER DOUBLE PERFORM..oh 30% improvement in AVP not double : [ ( this would be 30% faster than 6970 as well by the by)
Still, looking forward to the TPU review on the 22nd to see if results are anywhere close to this!
j/k :p
So, based on the graph, I come up with the 7970 being about 48% faster than the GTX 580 on average.
1. remember Buldozzer graphs?
2. if you have to cash (major price increase vs 6970) for every increased frame then it is no use of this new GPU generation and you copuld get that kind of preformance increase and just grab 6990 or 6950x2 for same price!
More maths: Using W1zz's reviews for readings, the 7970 gets 11 FPS more in Metro 2033 then the GTX 580 3gb card.

Nice move AMD but we got u :D
