A Centrino 1.3 GHz is only slightly slower than my Athlon 2 GHz (2400+) for running chess programs. A Centrino 1.5 GHz and 1.7 GHz will surely be faster than an Athlon 2 GHz, so it is a good CPU to get if you can afford it. My brother has a laptop with a Centrino, and it runs very quiet too. As for why it is faster, I believe they basically took a PIII and gave it a longer pipeline (which the P4 has), but the Centrino has much better branch prediction. And there is the larger cache. A P4 may be at 3GHz, but the branch prediction isn't as good, and with a longer pipeline, that's not a good situation.
