Bitcoin Pass Recovery (Thegrideon Software)

"The final password recovery speed is equal to CPUspeed + GPU(1)speed + ... + GPU(N)speed. For example:"

Intel i3 + integrated HD 4400 GPU + AMD R9 270 = 90 + 70 + 2900 = ~3060 p/s."

Intel HD Graphics 4400 (12 CUs, i3 4130) 70 p/s 5.2 MH/s
AMD Radeon™ HD 6770 (10 CUs) 1228 (123/CU) 92 (9.2/CU)
AMD Radeon™ R9 270 (20 CUs) 2910 (145/CU) 218 (11/CU)
AMD Radeon™ R9 280X (32 CUs) 5000 (156/CU) 375 (11.7/CU)
NVIDIA GeForce GTX 470 (14 CUs, sm_20) 932 (67/CU) 70 (5/CU)
NVIDIA GT 640 (just 2 CUs, Kepler, sm_35) 450 (225/CU) 34 (17/CU)

Hmmm, interesting....
