cpu performance Flashcards
what is cache memory?
it is temporary storage for frequently accessed data
how does cache memory improve performance?
cache memory is closer to the cpu than ram, meaning that it can provide data and instructions to the CPU at a faster rate.
A computer with more cache memory should gave a higher performance because repeatedly used instructions can be stored and accessed faster
what is a limitation of cache memory?
it is costly , so more computers have only a small amount
what is clock speed?
it is a measure of how quickly a CPU can process instructions
3.5ghz means…
it can perform 3.5 billion cycles per second
the faster the clockspeed …
tehh faster the computer can perform the fde cycle resulting in better performance. because more instructions can be processed every second
underclocking will result to ….
slower spped on the computer but a longer lifespan
overclocking will result to …
faster speed but it may make the machine overheat and could damage the machine
what is a core?
it is a complete set of cpu components.Each core is able to perform its own fde cycle
How does the number of cores improve performance?
a machine with more cores will perform better because it can process more instructions at once
a dual core proccessor procceses _______ instructions at a time
2
what are the limitations of more cores?
if one core is waiting for another core to finish the performance may not increase at all
some software is not written to use multiple cores so it will not run any quicker
