The appropriate answer is always amd64. The last I looked at benchmarks |
| 20 |
was quite a long time ago, but I think there is improvement to running |
| 21 |
32 bit programs inside a 64 bit OS. The newer chips are more than just a |
| 22 |
new instruction set. They contain a lot of machinery to make boring things, |
| 23 |
like context switching, faster. |
