The average CPU power (ACP), is a scheme to characterize power consumption of new central processing units under "average" daily usage, especially server processors, the rating scheme is defined by Advanced Micro Devices (AMD) for use in its line of processors based on the K10 microarchitecture (Opteron 8300 and 2300 series processors). This rating is similar to Intel's thermal design power (TDP) used with Pentium and Core 2 processors, measuring the energy consumption of high workloads, which in numbers are slightly lower than the TDP value of the same processor.
AMD claims the ACP rating includes the power consumption when running several benchmarks, like TPC-C, SPECcpu2006, SPECjbb2005 and STREAM Benchmark (memory bandwidth) which AMD said is a better method as a power consumption measurement for data centers and server intensive workload environments. AMD has said that the ACP and TDP values of the processors will co-exist, and do not replace one another. All server products will see two power figures starting from the codenamed Barcelona server processor onwards.

Famous quotes containing the words average and/or power:
“One cannot develop taste from what is of average quality but only from the very best.”
—Johann Wolfgang Von Goethe (1749–1832)
“Now narrow minds can develop as well through persecution as through benevolence; they can assure themselves of their power by tyrannizing cruelly or beneficently over others; they go the way their nature guides them. Add to this the guidance of interest, and you will have the key to most social riddles.”
—Honoré De Balzac (1799–1850)
