1

What affects CPU performance?

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

2

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.

3

How does Pipelining affect CPU performance?

Pipelining is used to make sure that instructions are run

4

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.
