Nvidia confirms the GTX 580

[trinibwoy]

c) GTX 580 isn't as big a change from the 480 as people think, and so it was easy to push into production

Easier maybe but leaks don't come from chip manufacturing usually, they come from board manufacturing and the 580 rumours so far suggest a new PCB/cooler.

Oh btw, the leaked Vantage feature tests show that it is just 64 TMUs.

The respin of GF100 with drivers that "cheat" (they'll probably point AMD out for cheating and do the same) seems more likely than ever.

How does having 64 TMUs make it likely they will "cheat"? Care to elaborate?
