Summary: 32-bit wide address bus


A 32-bit address bus is useful even if you don't have 4Gb of physical memory.
I can think of several programs I have written that while running have a
virtual image greater than 16Mb.  It's much nicer to work in a big virtual
address space and let the OS worry about the physical memory.

In case you're curious, one of the above-mentioned programs was a ray tracing
package, and one was, of all things, a model of Usenet a couple of years ago.

Each of these ran much faster and were much easier to write than if I had
done swapping, etc. myself, and added another layer of overhead.

Compilers and OS's are one thing, but there are large applications out here
as well.
