When you turn up the clock speed, and get more CPW out of a CPU, it always

This isn't always the case - for example, the old 130nm Preston
P4/Xeons had a TDP of 130W - at 3.2 Ghz.

Now you can buy a Core i5-750 that can clock one of it's cores to 3.2
Ghz while still being in the 95W TDP. Or it can run all 4 cores at
2.66 Ghz - all the while keeping in the 95W envelope.

Oh, and the Core i5-750 is much faster clock-per-lock than a P4.
