Can someone explain to me how many GHz a processor has if its, lets say, a 2.66 GHz core i5. is each core 2.66 GHz, or does the sum of all the cores equal 2.66 GHz?
 
heres an analogy for you, you have 1 car going 100 kph. Now you put another car next to it also doing 100kph. Are both cars now doing 200kph??? no they are both separately doing 100kph each. just like 1 core at 2.6ghz or 2 cores at 2.6 ghz each. However if there are 2 cores doing 2.6 ghz vs 1 core, 2 cores are theoretically capable of doing 2x more calculations than just 1.
