ITPEC IP October 2018 — Question 12 of 100
For a CPU with the same architecture, a higher clock frequency generally increases processing speed. More clock cycles can be executed per second, so work expressed in a similar number of cycles can finish sooner. The architecture condition matters because frequency alone cannot fairly compare different designs.
Answer (c)
Why not others:
- a 64-bit CPU can handle wider data than a 32-bit CPU
- reducing cache capacity tends to increase slow main-memory accesses
- a quad-core CPU has more processing cores than a dual-core CPU
Key rule: Within the same architecture, performance generally rises with clock frequency, although memory, workload, and other limits also matter.
