AMD Cayman info (or rumor)

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



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..

Another good way to look at it. Been awhile since AMD took a chance. Hoping they go all out and bring a real enthusiast powerhouse since this was originally meant for 32nm.

I invit you to read the report of Beyond3D about Fermi architecture ( vs Cypress ), and see where the strong and the weakness are on Cypress ... and just imagine if they have work a little bit on thoses weakness ( parrallel/geometry / data flow loss) how much the gain can be against Fermi... this will not come only by the 4VLIW ( who increase double floating point perf by around 20-25% and single precision by 40%( 1 cycle will be executed 20% faster just by this change for double float precision, and 40% for single at minimum)....
