I've been looking at processors lately, and I have noticed a new processor from AMD. It's called the sempron, and I can't figure out what it is. They almost appear to be Athlon XP chips that have been renamed. However, none of them feature the larger 512 L2 cache or the 400 mHz FSB of the higher-end Bartons. Also, them seem to come in both soket A and Socket 754 solutions. They seem to be priced slightly cheaper than their Barton preformance counterpart. Anyone know anything about these chips?
