CPU Benchmarking is the process of evaluating the performance of a central processing unit (CPU) by running specific tests and comparing the results. These tests measure various aspects of the CPU's capabilities, such as processing speed, efficiency, and multitasking ability. The results help users understand how well a CPU can handle different tasks, from gaming to data processing. Benchmarking tools, like Cinebench and Geekbench, provide standardized tests that produce numerical scores. These scores allow consumers and professionals to compare different CPUs and make informed decisions when purchasing or upgrading their systems.
