The myth is that SOI is the reason, but this is absurd.

What is absurd is making a definitive statement like that when you have no idea.

To know that SOI has no benefit, you'd need to compare two architecturaly-identical chips, alike in all respects save SOI.

Hammer runs at faster clockspeeds than Athlon, a simpler design but 130nm nevertheless. That's enough proof for me that SOI may provide some non-negligible benefit.

Who are you to say that Opteron would be just as fast without SOI?

Do you know for a fact that Prescott or Dothan wouldn't improve with SOI?

Or do you just take Intel's word for it?
