HM, the 64-bit question is moot. Intel has it, too.

The only point I'm trying to make is that the overhead is greater than most people realize. The extra registers don't make that much of a difference, since most of the bottle neck has already been removed from them with the advent of register renaming. If you are expecting >0% improvement in *all* 32-bit apps, and >>0% in 64-bit apps, you are going to be in for a huge disappointment. Your Linux recompiles are probably mostly based on the fact that GNU is a relatively slow 32-bit compiler.
