Very interesting... newegg.com has both listed. Like you say, one has 64kb x2 and the other has 128kb x2. Yet both are supposed to be Denmark cores. After doing some reading on other forums, a lot of people have the same question.
It appears that are 2 different Opteron 165 cores... one with 2x 64kb L1 caches and another with 2x 128kb L1 caches.
My X2 4200+ Manchester says I have the 64kb x2 caches. See here:
youre going by what newegg says... both processors have 64kb*2 cache, on both cores. the difference between the newegg ones is one is retail and one is oem, the retail was 355 before and now it dropped to 325, end of story.
