A you know, a ingle CPU procee one intruction at a time. Adding a econd CPU (or core, in current terminology) allow the ytem to proce two intruction imultaneouly, effectively doubling the proceing power of the ytem. A third core will offer triple the proceing power of a ingle CPU, and o on. However, tudie have hown that, in general, the expected increae in computing power tart to decline when the number of core grow large, beyond eight or o. Why doe thi appear to be the cae? For what type of computing problem might thi not be true? How doe multithreading in a CPU help performance?
