Re: Differences between amd64 and i386.


Debian amd64 has a processing speed advantage in being able to use more registers, reducing the amount of data that has to be shuffled between registers and cache during execution. There are other architectural advantages, too. Obviously, the OS takes pretty full advantage of this internally. However, a lot of the 64-bit stuff is used only by programs that are written for a 64-bit platform, afaik.

Dear Friends,

What are the main advantages of debian amd64 compared to i386 debian besides to address more than 4GB of memory?

The standard Debian 6.0 kernel image of i386 has already been compiled with SMP-alternatives support.

Are there differences in processing speed between them?
