Latest Bounties as at 19th March Notes for CUDAMiner bounty: If a R9 280x gets 2100 kh/s in X11 and 750 kh/s in scrypt (a ratio of 2.

, X11 cudaminer performance should achieve at least: 0.7 * 2.8 = 1.96 times Nvidia CUDAMiner scrypt performance
Just curious, but I am getting roughly 2.2x performance on my GTX460 using the same version of sgminer I am using for my ATI cards. Am I just lucky sgminer is working with my Nvidia card and is that why their is a bounty for a CUDAminer optimization?
I mine at about 370 per core on my GTX 690s with sgminer - but I think a real cudaminer port will bring that speed way up.
I talked to the cudaminer developer, but so far no interest.
