- Sempron 64 bit operation

I am putting together a computer for a friend and I am considering that
64 bit operation might be useful over the next couple of years. I
expect them to have this machine for as much as 5 years (their old one
is from '99), so I want to keep it inexpensive, but as functional as
So I am looking at the Sempron CPU and wondering if there is much
advantage to getting the Sempron 64. I'm not clear on whether the
Sempron 64 offers the full 64 bit capability of the Athlon 64. I did
some searching on google, but didn't find anything that explained it
clearly. I know that the Sempron is just a renamed Barton and the
Sempron 64 is based on the Athlon 64 core, but have the 64 bit
instructions been disabled? Or is the Sempron 64 just an Athlon 64
with reduced cache or something similar?
Re: Sempron 64 bit operation
Some Sempron socket 754 CPUs have the 64-bit instruction set disabled,
some have it enabled. But either way, its still a socket 754 CPU.
If the computer will be used for 5 years, my suggestion is to go with a
low- to mid-range socket 939 CPU. The Athlon 64 3500+ Venice is around
$200 and the 3700+ San Diego is about $30 more. These will provde
better performance over that time.
