[OT] CPU and GHz

2007-01-22 Thread Misko
I am just curious! Todays computers are running on high clock frequencies. If I have CPU that runs on (let say) 1 GHz what parts of hardware are actually running on this speed? (except crystal :) I understand that memory chips are much slower than CPU so every time that CPU need data that is not in
