The Tech Report took a look at cheap and affordable dual-core low-power processors from Intel and AMD:
The game is changing dramatically, however, with Intel's introduction of its new Core 2 Duo processors and AMD's retaliatory moves. Now, we have some excellent dual-core CPU options that combine solid performance with very low power use at prices around the $200 mark. What's more, because they have relatively modest clock speeds, they may have the potential to overclock like Floyd Landis in Stage 17. From Intel, there's the Core 2 Duo E6300, with 2MB of cache and microarchitectural roots in Intel's mobile products group. From AMD, there's the CPU with the longest name ever, the Athlon 64 X2 3800+ Energy Efficient Small Form Factor. You may use extra energy spitting out that massive moniker, but the chip promises to conserve thanks to its astounding 35W power rating.
