I don't know a great deal about what makes a good compiler, so maybe you or someone else can comment. GCC or VC++ may be able to compile code that will run on the Opteron, but will it be optimized well? There are a lot more registers than there are in the Athlon/P4 (16 64-bit GPR's, 16 128-bit XMM, 8 64-bit MMX). If you take the current GCC or VC.NET and compile, say, Crafty on an Opteron, will it take advantage of all of the new specs? I assume that at the very least, it would take advantage of the extra GPR's and larger cache?
