How much electricity do CPUs use compared to GPUs? For instance, would a high-end GPU mining BTC use more electricity than a high-end CPU mining LTC per unit time? Would the difference be significant?

Might've been asked already, but it's a huge thread to sift through, and there doesn't seem to be a wiki anywhere.

The wiki seems to be down, but here is a google cache of most gpus/cpus and their wattage, hashes, etc. Note that references to hashing is BTC only, but you should still be able to get an idea of watt usage.
