AMD Cayman info (or rumor)

[spursindonesia]

You mean over GTX 480? GTX 580 is coming out at $499 it appears by Amazon pricing, and will hopefully be 20-25% faster than the 480 in games, run cool & overclock well. The GTX 480 is already a good bit faster than the 5870 (especially in SLI/Crossfire 2x card mode).... so I sure hope that 6970 is more than 40% faster than a 5870 and then would still be deserving of a $400/less pricetag from the looks of things. Just my two cents . If it's only 40% faster than a 5870 (or thus maybe 10% than a GTX 480), and launched at $449-479 it would be a fail in my eyes.

First, GTX 280 only leads HD 5870 by around 15-20% on average

Second, i got a reliable source that i trust saying that GTX 580 will only be on average 15-20% faster than GTX 480 in real world gaming (while it will be a BEAST in 3DM Vantage Xtreme).

So, perhaps you should tame your expectation over GTX 580 a bit, it will be a decent refresh but not a second coming, never was. If you can do that, then perhaps my expectation won't be too extravagant in your eyes.

With that 40% jump, AMD has made a turn around from basically 15-20% behind in absolute performance into a level player in the enthusiast segment, still using the same 40 nm process node.

Regarding pricing, with around the same performance but costing around 10% less, i think that's plenty fair & competitive in the first place, already factoring nVidia lead in (propietary) features department.

Regarding OCing, we shall see, both sides have their own advantages & disadvantages regarding this. Serious OCer is still a small segment, even among enthusiasts, and OCing a beast like those cards won't be a walk in the park like their smaller brothers (GF104 and Bart based cards).
