Wow. Yet apparently there's still much room for improvement on both
cards. This gives some performance numbers for Ivan Golubev's code:

GTX 580 does 7400 c/s. There's no published number for HD 7970, but
judging by 5970's 19330 c/s we should be getting over 15k on 7970.
19330*2048*925/3200/725 = 15783
or going from 5770's 6285 c/s:
6285*2048*925/800/850 = 17509
