No, you can't really say that. In the same way 4 car engines doing 5000 RPM wouldn't give 20000 RPM.

Sounds like one of them ebay ads offering that crap.

It's simply 4 cores, 4 separate things running at 2GHz, they will never combine to make 8Ghz. If someone is offering an 8Ghz, they're trying to 'scam' you into buying a computer that isn't actually 8Ghz.

No. As IrishGrimReaper said, each core would run at the same speed, but a 3GHz quadcore is not the same as a single 12GHz processor.

If you look through the CPU benchmarks above, you will see that a quadcore processor may not perform much better than a dualcore CPU running at the same speed, for a given benchmark. This is because very little software is written to utilize all four cores, and a few other factors.
