  3. If you take a class in computer architecture you would understand the concept of cache, but since I take it you don't want to do that just go over to wikipedia

    http://en.wikipedia.org/wiki/CPU_cache

    Basically the CPU checks to see if it has what it needs in cache, if not then it has to wait for it to be retrieved from memory which takes longer. As for cache sizes you need to research the history of the CPUs you're interested in. Keep in mind that not all cache is created equal. For example, L2 cache on Brisbane AM2 CPUs is slightly slower than on AM2 Windsor CPUs.
