AMD Cayman info (or rumor)

[RPGWiZaRD]

50% more power than 6870, alteast 50% more performance than 6870, note also, that would put 6950 to 20-30% more performance than 6870.

Erm, you're forgetting power consumption / performance isn't a linear relationship. The higher you go the more inefficient and more leaking. Especially when we go over 200W territory. Cayman will probably not have the same performance efficiency as Barts, a 50% increase in power consumption may only translate to say 35~40% better performance for example unless architectural improvements are made in which the rumored shader arrangement might play a good part in, but the cards arrive quite soon anyways.
