Looks like AMD’s new 65nm processors aren’t going over as good as they’d have hoped for!

We’re a little perplexed by these developments. Why would AMD increase the latency of its L2 cache, especially without increasing its size? Why isn’t the die area of the 65nm Athlon 64 X2 even smaller compared to the 90nm version with the same transistor count? There are a number of possibilities, but I’ll refrain from speculating for now, and we’ll await some better answers from AMD.
