The CPU`s are identicle. Only difference is that the MP has been tested and proven to work properly in multiple CPU systems. About 80% of the XP`s CPU`s will work as MP`s if you connect one of the birdges but you have about 20% that wont work. All CPU`s by AMD are made as XP`s and they just pick the ones that are guartanteed to work as MP and label them as such.
