Nvidia intentionally cripples the double precision floating point performance of their "gaming" cards to make the market for Tesla cards.
AMD doesn't, which is why you don't see much firepro, and why their entire line sells for so much right now while mining on hashes is big.
- dustcoin 13y agoNeither sha256 (bitcoin) nor scrypt (litecoin) mining uses floating point operations. AMD cards are faster because they are built with more, simpler "cores", compared to Nvidia's fewer, more complex "cores". Mining benefits from the increased parallelization and doesn't benefit from Nvidia's "fancy" "cores". For sha256 mining, AMD cards gain an additional advantage by supporting a bit rotation instruction that Nvidia cards do not.
