AMD's 65nm L2 cache looks to be slower

Published by

After we published our first look at AMD's 65nm Athlon 64 X2 processors yesterday, some of you raised questions about funky performance numbers you'd seen from these 65nm CPUs at other sites.

We focused on power consumption and overclocking in our initial look at the processors, assuming those would be the most interesting aspects of the die-shrunk parts, which were billed as otherwise offering performance identical to their 90nm predecessors. We should have known better, given the difference in L2 cache performance we noticed between 130nm and 90nm Athlon 64 processors during AMD's last die shrink.
