2
Q
How can having a higher processor affect the performance of the CPU (2)
A
Faster/ Higher clock speed (1) More Fetch Execute Cycles (1) More Instructions can be executed per second
3
Q
Explain why having a quad- core processor will not always run twice as fast as a dual- core processor (3)
A
Software may be designed to run 1 core and not multiple (1) Dual core may have a faster clock speed than a quad core (1) Quad core may have less RAM (1) Quad core may have less cache (1)
