Nvidia confirms the GTX 580

[Dimitriman]

Actually, i think a full 512 SP chip with added TMUs of 128 would be a plenty decent chip if nVidia's engineer can pull it off. At least it would fit into Bart's description of reworking the chip design while the underlying mArch stays the same. No matter the end result is, from engineering stand point, that's quite an achievement & i respect that.

Now, if it's really just a respinned GF100 with exact amount of units & fully copied mArch, i'm gonna LOL, hard.

yes and i mean with all the changes you mentioned it will still be highly unlikely that 580 walks over cayman. Remember cayman will have 1920 4d shaders with ever further improvement to tesselation than barts as well as other architectural changes and 6gb/s memory.
