AMD’s VLIW architecture owns nVidia’s Fermi and older architectures in this case. More parallelized and that’s what Cryptography is all about. Would be interesting to see how AMD’s Graphics Core Next fares up for this purpose.
What does 5 billion MD5 brute forces per second mean?
MD5 Hash of a 7 char string containing only lower-case alphabets and numbers cracked within 30 seconds. Think how fast 8 x HD 6990s would be.
Note: oclHashcat-lite didn’t work for nVidia cards. Don’t know why. Could be either – software or driver issue. Don’t consider this an Apples-to-Apples comparison. But still this is the best what each platforms can offer.
