To date (thru 4.0.1), gcc treats all the amd64 family the same -- they are all aliased to each other, so to with them, it doesn't matter. I've seen some debate on the the newer processors, however, which have sse3, sempron included, AFAIK, and can't say I know enough about that to say for sure what's best there. For the vast majority of packages, any of the amd64 aliases will be optimal as they'd not likely use sse3 anyway. The exception would be any heavy multimedia or video, particularly encoding and decoding, but also possibly xorg/mesa. On that stuff, sse3 could make a difference and I don't know what would be best. (Note that in practice, support for sse3, as the newest addition in any case, may not be fully optimized yet, particularly on 64-bit. Look for better support there by gcc 4.1 or 4.2, after the potential of gcc 4 has had some time to mature as well.) -- Duncan - List replies preferred. No HTML msgs.
