# CPU Performance Factors The following factors affect CPU performance: ## 1. Decoding Instructions * The control unit decodes the instruction and sends control signals to the appropriate component. * The operation indicated by the instruction is performed. ## 2. Executing Instructions * The ALU performs the operation. * The value stored in the PC is changed. ## 3. Factors Affecting CPU Performance * **Cache memory:** A very small amount of fast memory inside the CPU. Accessing cache is much faster than accessing RAM. Storing frequently accessed data in the cache can speed up processing and avoid the slower process of retrieving data from RAM. * **Clock Speed:** The CPU's clock sends pulses at fixed intervals to trigger the next stage of the operation cycle. A higher clock speed means more pulses per second, allowing for more instructions to be executed in the same amount of time. * **Cores:** Each core of a CPU can process instructions independently. Multiple cores allow a CPU to process more than one instruction at a time. **Diagram:** A simple diagram is shown of a CPU with labels for Core two, Cache, CU (Control Unit), and ALU (Arithmetic Logic Unit), and Main memory.
