Should be around 2x of what we have today on GTX 285, around 1500.
Clock speed is a mistery now, it might get lower (so that power dissipation would not get 1.5x higher), or little higher (if getting rid of huge DDR3 controller saved us lots of heat)

L1/L2 caches are nice, but would not help in bruteforcing at all.
So all we have now it almost only extensive scaling : more silicon thinner tech, that's it.

It might make a little better than linear improvement in games & memory-bound apps, but unfortunately this is not our case.

Out of order execution is a mistery - not sure what they've meant there, but if it would able to do 2 arbitrary commands at once - they would scream about it, so looks like it's not the case.

Also they will give us 4x more FP64 performance (2x of which is extensive), but this would not help us too :-)

Tesla C2050-datasheet: http://www.nvidia.com/docs/IO/43395/BD- ... 01_v01.pdf
Tesla C2050 = Fermi
GPU
Number of processor cores: 448
Tesla C2050:
up to 600 GFLOPs/sec of double precision processing performance
ATI 5870:
Processing power (double precision): 544 GigaFLOPS
My ATI 5850 with 418 GigaFLOPS (double precision): ~950mHash/s (Processing power (single precision): 2.09 TeraFLOPS :crazy: )
So a C2050 should produce ~1350mHash/s or something like that ;)
