Seneca factors affecting CPU Flashcards
What are the 3 factors that affect CPU performance
Cache, Cores, Clock speed
Cache
small amount of very fast memory inside the CPU
In comparison to the cache, accessing the Random Access Memory (RAM) is a very slow operation
By storing frequently accessed data and instructions in cache memory we can avoid the process of accessing the RAM.
Cores
Each core of a CPU is capable of processing instructions independently
Each core has its own Control Unit (CU), and Arithmetic and Logic Unit (ALU), but the cores share access to cache and main memory
Multiple cores allows a CPU to process multiple instructions at the same time
Clock Speed
Multiple cores allows a CPU to process multiple instructions at the same time
higher the clock speed, the more pulses are sent per second, so more instructions can be executed in the same amount of time
