Lots gained nothing at all. The only one that gained more than 1% or so was Shredder 8, and that was about 3%. If you'd like the exact numbers I'll try to dig up the old post I made here a month or so ago. Also, they have Semprons for Socket 754 (Athlon 64) based systems. These should be pretty much identical in speed to Athlon 64 at the same clock speed as far as chess goes. Adding extra memory bandwidth and L2 is NOT cost effective for increasing chess speed. The gain is in most cases nothing, and when you do get a gain it is extremely small.
