Adding AMD64 is no trivial task. Busses, registers, ALUs, everything has to be twice as wide. If the CPU wasn't designed for it, it may drop a bunch of speed grades. Witness the original Opteron that ran at 800 MHz. That was the one that Sanders gloated about needing only 5% more die size to do AMD64. Well, guess what, he was wrong. I believe Prescott was originally designed for some other kind of 64-bit, so data paths were probably already there. Better to start from scratch with AMD64 in mind. Presumably what Conroe/Merom will be. Petz
