AMD Cayman info (or rumor)

[Mechanical Man]

IF it is 4D, 1920 shaders, and 860 clock I'm going to predict about 50% faster then a 5870 in most games. In games with heavy tessellation it should be more, but it isn't clear how much.

I guarantee you, it is 4D. Very reliable source.

I posed this question in another forum. What about AMD's sweet spot strategy. They always like to keep margins high with respect production costs. If this is true TDP would be more like 225W and smaller die than what is rumored. If that's the case they are just happy to sit within 10% of GTX 580 or just below it.

HD6950 has PCI-e 6+6pin connectors, so <=225W, HD6970 has 6+8pin connectors so <=300W.

HD6870 has 6+6pin and is <150 in real powerdraw. I would guess from that that HD6970 is ~210-230W. Think about what 50% more power gives you in performance compared to Barts..
