What are the performance metrics of a CPU? What does it mean? Points!

1, CPU frequency, that is, the CPU clock frequency, simply put, is the frequency of CPU computing work (1 second synchronization pulse occurs within the number of abbreviations). The unit is Hz. It determines the speed at which the computer runs.

2, cache capacity to provide a data buffer, first read the data temporarily stored, and then a one-time transmission. Solve the speed matching gap with other devices. Temporary storage point for data when processing data.

3, Bus (Bus) is a computer between various functional components to transmit information on the public **** communication trunk, it is composed of wires transmission harness, according to the type of information transmitted by the computer, the computer's bus can be divided into data bus, address bus and control bus, respectively, used to transmit data, data address and control signals.

4, superscalar (superscalar) CPU architecture refers to a class of parallel operations in a processor core that implements instruction-level parallelism. This technology enables higher CPU throughput at the same CPU frequency.

5, CPU operating voltage (Supply Voltage), that is, the voltage required for normal operation of the CPU. The CPU's operating voltage has a very clear downward trend.
