OT: AMD processors: sempron or athlon xp

Which is faster a 2800+ sempron or a 2800 - 333 athlon xp? Either one will work in my motherboard (hopefully). Also which one runs cooler? I thought I read that AMD's mobile processors can be used in a desktop too(socket 462), anyone try this?

If you get the socket 754 sempron it is actually a 64 bit with the onboard memory controller the 64 bit is disabled but the memory controller is not.It only runs at 1.6,so get a board that overclocks and it should beat the pants off an xp chip. The sempron will run cooler as well. Tim "John Smith" <[email hidden]> wrote in message news:WhY0f.4163$[email hidden]... > Which is faster a 2800+ sempron or a 2800 - 333 athlon xp?

To compliment Tim's reply, for Socket A the Althon is faster for a given 'rating' (2800 etc), I believe the sepron rating is equivalent to duron/celery clock speed rather than Athlon/P3. Check the cache & actual clock speed, you may find a good sempron cheaper than a similar spec (but different rating) Athlon for less money. You get what you pay for at the end of the day ;-) Malc.

I believe this site has the best info about computers: www23.tomshardware.com/index.html I came from work, so I am too tired to go through this list, but the problem is in cache. I think sempron has 256kb, and athlon xp has 512. 2800+ sempron is the same as 2400+ athlon xp, in speed. -- Mario

I noticed the cache size was smaller on the sempron. I did find that the clock speed isn't locked on the mobile sempron, however they are getting harder to find and more expensive. I was hoping to just do a chip upgrade instead of mobo v/card and ram.. The mobile sempron 2800 is easily oced at 2.4gig according to a lot of posts on newegg..

I don't know about that mobile sempron. Cache is tight passage. If that mobile sempron has 256kb, I don't know how you can widen that passage. This is how they efficiently downgrade a processor, even if you oc it. But, I am not some big expert. Maybe it is OK. But, there is a sempron with bigger cache. It is 3000+ or 3200+ (I am not sure), and I think it is as much fast. Try to find if you can put that sempron onto your MB. BTW, AMD stretched 3000+ speed number (I don't know about 2800+). 3000+ is only some 10% faster than 2400+. But this 10% is really what you need, if you have 2400+. I upgraded from Athlon XP 2400+ (Thoroughbred) to Athlon XP 3000+ (Barton, I hardly found it), and it is very much worth it. I also only looked for a chip upgrade. -- Mario

Most, but not all, motherboards can accomdate the chip. OC to ~2.4 gig with moderate voltages is common.
