Leaked - AMD Barcelona versus Intel Clovertown and Tigerton
 

Since the leaked slides indicated that the performance estimates were submitted to SPEC.org on 8/20/2007, that looks fairly new to me though it does not rule out the possibility of newer and better numbers for AMD. I *cannot vouch* for the accuracy of the Barcelona leaked numbers and I cannot rule out the existence of newer Barcelona numbers. But since the slides look authentic and the performance numbers are within the expected range, I’ve decided to post the performance numbers and let the reader decide if they’re authentic or not.
