The Top 10

1. Intel Core Duo
Notebook/Desktop CPU ($450 and up) Intel's Core Duo provides multitasking power never before possible on a portable PC, and yet it supports astounding battery life for mobile devices. The Core Duo processor is so good that it's the CPU of choice not only for Windows laptops but also for Apple's Windows-capable laptop and for desktop Macs.

In today's mobile world, Core Duo gives Intel a leg up. AMD's Athlon 64 X2 Dual-Core (#2) is astoundingly good, but AMD hasn't yet captured that power in a mobile version; and its notebook processors aren't nearly as potent or as battery-efficient as Intel's. Review | Latest Prices

2. AMD Athlon 64 X2 Dual-Core
