What Determines CPU Performance?
The performance of a CPU is determined by its frequency (or clock speed), architecture and cache. The architecture of CPUs is constantly evolving, and with this we get faster processors that run cooler and more efficiently. Multiple core CPUs are a prime example of architecture improvement. Two or more cores allow data to be processed more efficiently therefore increasing performance, sometimes even with smaller clock speeds. The performance difference between single and multiple core CPUs is dependent on the software and OS you are running. With overclocking we can’t change architecture because it is a physical component. The only way to alter architecture is to buy a new CPU altogether. Clock speed is the rate in which data is processed. It is common for people to get confused with this idea and assume that a bigger clock speed CPU runs faster than a lower clocked CPU. This is not necessarily true, especially when there is a major architecture difference. An interesting comparison of
