There are 3 (not 2) flavors of mobile A64s. 2 of them have 1 meg of L2 cache. One is rated at 81.5W (the DTR mobile), the other at 62W (the mainstream mobile). I suspect the former is the one that has been shipping in HP notebooks, and the latter is the new part introduced today.

(There is a third category, which is the low power mobile parts of 35W, of which there are two representatives: te 2700+ and the 2800+. And of course, there are the desktop A64s at 89W.)

"There are two flavors of mobile A64s. One has 1 meg. of L2 cache and is rated at a TDP of 57-65 watts. The other is a low power version that has 512k and a TDP of 35 watts."

Hmm... I hadn't given this a whole lot of thought, but, given two chips with similar performance, shouldn't a big cache chip use less power power than a small cache chip? (i.e. because the clock on the big cache chip would be lower, and the cache doesn't take much juice)
