What effects CPU performance
Clock Speed
Clock Speed
Clock speed is the number of pulses the central processing unit's (CPU) clock generates per second. It is measured in hertz.
Cache Size
Cache Size
Cache is a small amount of high-speed random access memory (RAM) built directly within the processor. It is used to temporarily hold data and instructions that the processor is likely to reuse.
Number of Cores
Number of Cores
A processing unit within a CPU is known as a core. Each core is capable of fetching, decoding and executing its own instructions
Why does each of these effect CPU performance?
Clock Speed
The more pulses per second, the more fetch-decode-execute cycles that can be performed and the more instructions that are processed in a given space of time. Overclocking can cause long term damage to the CPU as it is working harder and producing more heat. The average CPU clock speed is around 2.3-2.69 Ghz (according to steam hardware survery 2022) and the highest a CPU has ever been clocked to is 8.812GHz!
Cache Size
The bigger its cache, the less time a processor has to wait for instructions to be fetched.
Number Of Cores
The more cores a CPU has, the greater the number of instructions it can process in a given space of time. Many modern CPUs are dual (two) or quad (four) core processors. This provides vastly superior processing power.
