GCSE Computer Science (OCR J277) – CPU Performance (1.1.2)

This resource focuses on 1.1.2 CPU Performance, helping students understand how key characteristics impact the overall performance of a processor.

It covers:

Clock speed – how the number of cycles per second affects processing speed
Cache size – how storing frequently used data closer to the CPU improves efficiency
Number of cores – how multiple cores allow parallel processing and multitasking

Students will develop:

A clear understanding of each performance factor
The ability to explain how changes to these characteristics affect system performance
The ability to analyse performance both individually and in combination

This resource is ideal for GCSE Computer Science (OCR J277) and supports both revision and classroom delivery.
