ITPEC IP April 2021 — Question 13 of 100
For the same CPU architecture, a higher clock frequency generally increases processing speed. More clock cycles occur each second, so work expressed in a similar number of cycles can finish sooner, although heat, memory delays, and other limits still affect real performance.
Answer (c)
Why not others:
- a 64-bit CPU can handle wider data than a 32-bit CPU
- reducing cache capacity does not make processing faster and may increase slower memory access
- a quad-core CPU has more cores for concurrent work than a dual-core CPU
Key rule: Compare clock frequency as a speed indicator only when CPU architecture and other conditions are comparable.
