AMD Cayman info (or rumor)

[Dimitriman]

Hum lets see performance speculation from an nvidia boy point of view:

Well gtx 480= 30% faster than 5870 on ALL cases at the very LEAST
gtx 580= 20% faster than 480 AT LEAST its fact and I know it cause I saw a vantage mark somewhere in a chinese forum.
gtx 580 = faster than 6970 - this is just given and automatic fact.

since gtx 480 is 30% faster than 5870 and 580 is 56% faster than 5870 (at least and everywhere) then, 6970 will be right in the middle (cause AMD is mediocre & budget) and is 28% faster than 5870.
