1.1.2 CPU performance

Question 1

How does the clock speed affect CPU performance?

Answer 1

If you increase the clock speed, you increase the amount of fetch-decode-execute cycles which take place per second meaning that the CPU will be able to process data faster.

Question 2

How does the cache size affect CPU performance?

Answer 2

If you increase the cache size it means that there is more storage for you to quickly read and write data to. And there is less chance of needing to go to the RAM

Question 3

How does the number of cores affect CPU performance?

Answer 3

Because more cores allows multiple cores (ALU, control units,cache, etc) to work simultaneously to complete more fetch-decode-execute cycles at once.

Question 4

Why does a dual core processor not always operate twice as quick as a single core processor?

Answer 4

Because some codes need to be processed one after the other, so the processors wont be able to work simultaneously.

Question 5

what are the other factors that affect the CPU

Answer 5

over-clocking
age
cooling

Question 6

what is overclocking

Answer 6

is increasing the multiplier on the CPU, allowing it to run faster.

Question 7

what is cooling

Answer 7

Computer cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits
