What affects CPU performance?

Clock speed, number of cores and cache memory all affect CPU performance and pipelining


How does number of cores affect CPU performance?

Each core is able to process a different instruction at the same time with its own fetch-decode-execute cycle, making the processor two or even four times faster with a quad-core chip.


How does Pipelining affect CPU performance?

Pipelining is used to make sure that instructions are run


How does cache memory affect CPU performance?

the larger the cache size, the faster the data transfer and the better the CPU performance. However, cache is very expensive.
