Re: So hybrid 65/90 nm SOI process technology is how AMD's Turion
manages to provide twice the processing power (with 64-bit wide ALUs, registers, shadow registers, etc.) while using about the same power.

Note that moving from 2meg to 4meg cache on a Xeon adds about a watt of power consumption - almost all of the power used by modern CPUs is used by the (relatively) small number of very high speed gates in the CPU's core logic - and AMD's Turion has twice the core logic of Intel's Pentium M CPU since it processes 64-bits at a time vs. Pentium M's 32-bits.

Intel flat out stated during their last conference call that even their follow on mobile core (Yonah) would have to remain 32-bit because even Intel's upcoming 65nm process wouldn't get the power requirements down low enough to support a mobile 64-bit part.

Intel can talk about how much it spends on its FABs until the cows come home, but it can't seem to ship a process that results in high performance parts that have reasonable power budgets.

And in this business, you've got to be able to ship the parts.
