CPU performance is determined by CPI (number of cycles per instruction) and IC (number of instructions). CPI represents the number of clock cycles required for each instruction to execute, while IC represents the number of instructions executed.
A lower CPI and higher IC means the CPU is able to execute more instructions in less time, resulting in improved performance.
Therefore, by comparing the CPI and IC of different cpus, it is possible to determine which CPU has better performance.
However, other factors such as clock rate, cache size, and architecture should also be considered to fully evaluate the CPU's performance.
According to the CPU model, spec, capacity, power and so on can be judged
