1. A central processing unit (CPU) performance adjustment method, comprising:
determining, by a baseboard management controller (BMC), a rated power of a power supply unit (PSU) powering the current central processing unit (CPU);
outputting, by a complex programmable logic device (CPLD), a control signal corresponding to the rated power;
outputting, by a preset conversion unit, a voltage value corresponding to the control signal; and
determining, based on the voltage value and a first preset mapping relationship, a maximum operating frequency of the CPU in an overclocking state,
wherein the first preset mapping relationship is a corresponding relationship between voltage ranges and maximum operating frequencies;
wherein the outputting, by the preset conversion unit, the voltage value corresponding to the control signal comprises:
controlling, based on the control signal, a metal-oxide-semiconductor field-effect transistor (MOS) in a target branch of the preset conversion unit to turn on, and obtaining the voltage value corresponding to the control signal by performing a voltage division on a reference voltage using a divider resistor on the target branch,
wherein the reference voltage is a voltage converted from a supply voltage of the PSU, and resistance values of the divider resistors in different branches of the preset conversion unit are different, and the target branch is one branch of the preset conversion unit.
