what is the difference between athlon xp and xp-m?

XP-Ms are rated to run at the same speeds as XPs, just at much lower voltages, meaning that they run cooler at stock speeds and have more potential to overclock higher.

the only difference is that the xp-m is made for laptops while the xp is made for desktops

xp's are locked (except for the newere 55w bartons) while the mobiles are unlocked (meaning you have access to all the mults)...

xp-ms run cooler at stock vs the xp at the same speed due to the lower voltage it needs...

yeah that's all i can think of at the moment...

oh btw, you can use the axp-m in desktops!

The only difference is the purity of the silicon used. The AXP-M are designed to take higher heat, and overall much higher stresses than a desktop. Because of their more stringent quality control along with the lower vcore makes them clock higher because the silicon is physically better

So there would be no difference in gaming benchmarks I take it? Could you further elaborate about "unlocking" btw? I've heard that term used but I don't quite understand what it entails. I have the money for only either a athlon 2500-2700xp. The 2500 isn't a barton core though is it? What model should I be looking for?

It depends if you are going to overclock it.

As far as differences in gaming benchmarks.... if running both at stock then no you shouldn't see any difference. You will however see a difference in temps.

When a processor is 'unlocked' it means that the multipliers can be adjusted. FSB (RAM speed) * multiplier = Clcok Speed. The XP-Ms come unlocked by default since they are designed to be used in a laptop and the laptop needs to be able to adjust the processor speed based on load. I haven't heard yay or nay toward any desktop Bartons being unlocked after week 39 of 2003... so I can't speak to the 55W 2500+s being unlocked.

The 2200+, 2400+, 2500+, 2600+, 2800+, 3000+, and 3200+ are available in Barton cores. The thing to look for will be the L2 cache size. It should be 512K. As for which chip you should look for... If you intend to overclock you will first need a good board, preferably one with the nforce 2 ultra 400 chipset. Abit NF7-S is good, and I've heard good things about the DFI Lanparty. Anyway, if you intend to overclock, the 2400+ XP-M is a very good choice, as are the 2500+ XP-M and the 2600+ Xp-M. Don't even bother with a desktop Barton if you intend to overclock it.


I hope that all this has been helpful...

Yes very helpful. I think I'm going to go with the 2400 or 2500 xp-m.

That's not entirely true.

The AXP-M runs at 133MHz FSB and the Barton versions of the AXP run at 166MHz FSB (and 200MHz FSB for the 3200+). But if you change the FSB and multiplier to the same speeds, then yes, the performance will be the same.

That is true... but seeing as how most boards default the mobiles to 500-600 MHz right off tha bat anyway I was neglecting the difference in FSB (besides... I've never run it stock anyway....)
