Found this blurb on slashdot.org
Yesterday at Black Hat USA 2009, a talk entitled MD5 Chosen-Prefix Collisions on GPUs (whitepaper) (Both PDFs) presented an implementation written in assembly language for ATI video cards that achieves 1.6 billion MD5 hash/sec, or 2.2 billion MD5 hash/sec with reversing, on an ATI Radeon HD 4850 X2
and I am starting to wonder - how would CUDA stack up against this benchmark? Any takers?
1.6 billion per second sounds like an awful lots of hashes. ;)
