Details of NVIDIA's GeForce GTX 580 have spilled out in earnest today with a pair of Chinese leaks. Specs have emerged from Chiphell that back the notion of it having 512 processing cores (CUDA cores) but add that it would have a 772MHz core clock and 2GHz memory. It would have more memory bandwidth at 192.4GB, but contrary to rumors it would still use a 384-bit memory bus and rely mostly on brute force to run faster.
