Many benchmark software programs can test various components such as the CPU, hard drive, RAM and GPU. The best free benchmark software should have a variety of tests to assess multiple areas of the PC’s performance.
Each component has various metrics and types of tests to determine performance. While GPU benchmarks tend to focus on the ability to let games run smoothly, CPU benchmarks focus on multitasking capabilities. For example, GPUs can perform complex tasks much faster than a CPU, reflecting on the tasks used to test the component.
