But a newer CPU with a lower clock speed will beat the older, faster CPU most of the time as it is more efficient thanks to other improvements in technology. greatly affects the amount of tasks each core can churn through at a given period of time Instruction pipelining or just pipelining is a series of instructions that a CPU can handle in parallel to maximize efficiency. Each clock cycle, the processor should move from one valid state to the correct succeeding valid state. Assuming a constant clock speed (as well as everything else in the architecture being constant), and assuming memory reads/writes are the same speed (we assume 1 clock cycle here, but this is far from the case in real life), there is no direct speed advantage from a 32-bit to a 64-bit processor, except when using higher-precision values, or lots of memory reads/writes are required. If the same number of cores then consider the latest generation and high clock speed. To make things easier to understand think of the CPU not as the brains but as the brawn. So if you are having the same generation of processors then check which one is having the more core and clock speed. Thus, a CPU with a better architecture but lower clock speed may perform better than that with higher clock speed but less efficient architecture. The CPU is driven by a clock which is a square wave oscillator. The clock speed of the CPU is relevant because it tells us how many times your CPU can retrieve and interpret new instructions. Well, actually it's 3,733MHz if you really want to push it as far as you can go. Having more slower cores is still much better for productivity tasks.How Does CPU Clock Speed Affect Gaming Performance?
