AMD has problems with power leakage on their 65nm CPUs
Yesterday, we said we would talk about the prospects of AMD getting competitive K10 chips out.
We've suspected based on circumstantial evidence that AMD's core problem has been the 65nm SOI process.
Now someone has come up with some hard evidence that this in fact has been the case.
You really should look at the link; it's excellent detective work, but what the gentleman did was go to the AMD datasheets and compare the amperages used by various 65nm and 90nm AMD chips when in Halt/Stop Grant states (i.e., an idle state for CPUs).

Makes you wonder why they make the decision to not go with their new IBM/AMD developed high-K dielectrics and metal transistor process for the 65nm node in place of SOI. Instead they chose to use it for their 45nm parts next year, hopefully they will last that long while remaining in one piece.
