I'd recommend pausing the video on the questions at the end to test yourself on this topic - additionally, make yourself flash cards to test yourself, example:

On the front: what affects the CPU performance?
On the back: The CPU clock speed will determine how many FDE cycles can be performed in one second. The CPU can execute more instructions with additional cores as each core works independently.
