General info

The base and maximum clock speed of the CPU Apple M1X, number of processing cores and threads.

CPU Cores and Base Frequency

The general performance of a CPU can easily be determined based on the number of its cores and the thread count, as well as the base frequency and Turbo frequency. The more GHz and cores a CPU has, the better. Please note that high technical specs require using a powerful cooling system and a quality chipset (check VRM on the motherboard).
