Bah, don't take it harshly. Sorry if I came across rude. I was just sharing my own enlightenment on the topic. Just to be more specific.

Gigahertz refers to a type of frequency, which in this context.. as said by other users is speed.

When you say more lanes, does that mean that one of their processors can do more calculations per clock cycle than intel's? I always thought it was just one calculation per cycle.

Depends. AMD usually have a better core structure and higher memory bandwidth. As well as PowerPC's.

Although Intel usually have greater clock speeds. It doesn't necessarily mean they are faster than an AMD or PowerPC with a lower clock.

One GHz is a billion cycles per second. One MHz is a million cycles per second. One Hertz is one cycle per second.

USMA2010PowerPC processors, used on all the pre-Intel Core Apple computers (PowerBook, iBook, PowerPC G5) have more lanes.

I am not completely sure of the differences myself. I think that The PowerPC processor is just a more extreme variant of what AMD has done with the Athlon processors. They just "cut the fat".

For more info, see the wikipedia. http://en.wikipedia.org/wiki/RISC

Also, this article will provide a good bit of information as well. http://cse.stanford.edu/class/sophomore-college/projects-00/risc/risccisc/

Intel, and AMD are CISC processors, and PowerPC/Cell processors are RISC processors.
