Does anybody know - is an Athlon MP going to be identical to a same-rated XP, in a single processor board? Or is it a matter of trying it out as some boards will and some might not?
As far as I know xp's are mp's with the l5 bridge open

Its the same. Btw mobile athlon is same as Athlon MP. Tried to do bridge fix on Athlon XP - it works, but cpu is still not stable in dual cpu config. If you use single cpu mobo, there should be no difference.
Not only mine graphics cards collection at http://www.vgamuseum.info
Same chip. MP has SMP enabled, XP doesn't.

It is practically the same cpu. Despite just having the l5 bridge open, Barton 2800MPs are 266 fsb and that means you can also use them on single socket motherboards that won't tolerate 333fsb chips like my Dfi AD75.
Swaaye, the problem with XP-M chips is that in those old motherboards the chip will usually be interpreted at 800mhz, and since most of them only have multiplier adjustments via dip switches of up to 10x max you would be nowhere near of getting close to the 133x16 that 2800MPs run at

Yeah that is true. I forgot about the multiplier problem with old boards. I've messed around with socket wire mods but that is a lot of effort.
XP and MP are the same as has been previously said (they're all AMD K7s) - keep in mind differences in the core though; a lot of MPs are Thoroughbred or Palomino (there are only two Barton models; the 2600 (there is also a T-bred 2600!) and 2800). There are no 333/400FSB models either. Wikipedia has a list:

PRs should be comparable otherwise though.
