CPU Processors

OK I try to look this up but it goes so far into dtail i get lost. Wat is truly the difference between a Dual Core processor then a normal one? Say they are both 2.2 GHz. Is the DUal COre one like 4.4 or wat?

quad is the way to go!

Theoretically, it is 4.4GHz, but in practice, it's like ~3.0GHz. You basically have 2 brains in your computer, but they don't work at the full speed.

wrong, you have 2 cores on 1 chip, both running at 2.2 ghz, not "Theoretically, it is 4.4GHz". more cores you have the more processors you can execute at once. some programs use multi-thread and some still dont, the ones that dont only use 1 core not both so it will only run on one core at 2.2ghz not 4.4 or even 3.

I stand corrected. All this time I have been thinking that my processor runs at a theoretical amount of 6.0GHz. LOL! I have failed.

Not to mention that the gains are also non-linear. A quadcore gets a LOT more than a 4x benefit in a well-threaded game like UT4. Plus multicore processors have much more efficient individual cores so even in non-threaded apps they're still better. Plus you can run multiple non-threaded apps without nearly as much slowdown.
