Average CPU power

from Wikipedia, the free encyclopedia

Average CPU Power (abbreviation: ACP ) is a power loss specification for processors introduced by AMD . It is intended to supplement the thermal design power (TDP) value that has been used up to now . While the TDP indicates approximately the maximum power loss and serves as a guide value for cooling, the ACP indicates an average processor power loss under load (workload). AMD uses industry standard benchmarks such as SPEC to generate the workload . With previously released AMD processors, the ACP values ​​measured in this way are typically between 10 and 20 percent below the respective TDP values.

The ACP is thus similar to an older definition of thermal design power from Intel. AMD has been using this specification for server processors of the Opteron type since the introduction of the K10 microarchitecture . With the help of the Average CPU Power, AMD wants to simplify the determination of the typical CPU power consumption .

ACP compared to TDP

  • 40 watt ACP - 60 watt TDP
  • 55 watt ACP - 79 watt TDP
  • 75 watt ACP - 115 watt TDP
  • 105 watt ACP - 137 watt TDP
