Radeon HD 7000 Revealed: AMD to Mix GCN with VLIW4 & VLIW5 Architectures

[LordEC911]

30cu/1920 sp units probably 7950, if it's not fake..

I thought CUs had to be disabled in quads?
No way it is 7970 since Tahiti XT CU count is not divisible by 3.
I was thinking 28CUs 1792SPs.

well, if we look at the driver, pitcairn & tahiti are supposed to be the same architecture. just as a hint.

Correct.

and i can confirm that this is real.

Interesting...

CGN won't be much better than the legacy VLIW architecture in terms of efficiency. CGN is more like the current VLIW without the clauses, but keeps a very minimalistic approach to HW scheduling. It's still way behind what Nvidia have done ever since G80 in therms of scheduling and reordering, especially considering what Fermi can do now.

That's contrary to what I have been hearing, it sounds like a pretty big jump for AMD's GCN, just more moderate than what Nvidia has been doing.
