i just finished checking up on it and found that Pentium-M has twice the L2(1 mb) than pentium 4-M(512kb). so yeah, it is a new processor...hehe, kaya pala medyo confusing me pentium-M tapos me pentium 4-M.
pero yung centrino is the over-all "term", errr, right?

maybe this could help clear things out:
