To date (thru 4.0.1), gcc treats all the amd64 family the same -- they are |
8 |
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 |
11 |
sse3, sempron included, AFAIK, and can't say I know enough about that to |
12 |
say for sure what's best there. For the vast majority of packages, any of |
13 |
the amd64 aliases will be optimal as they'd not likely use sse3 anyway. |
14 |
The exception would be any heavy multimedia or video, particularly |
15 |
encoding and decoding, but also possibly xorg/mesa. On that stuff, sse3 |
16 |
could make a difference and I don't know what would be best. (Note that in |
17 |
practice, support for sse3, as the newest addition in any case, may not be |
18 |
fully optimized yet, particularly on 64-bit. Look for better support there |
19 |
by gcc 4.1 or 4.2, after the potential of gcc 4 has had some time to |
20 |
mature as well.) |
