Average CPU Power
Encyclopedia
The average CPU power is a scheme to characterize power consumption of new central processing unit
s 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 center
s 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.
Central processing unit
The central processing unit is the portion of a computer system that carries out the instructions of a computer program, to perform the basic arithmetical, logical, and input/output operations of the system. The CPU plays a role somewhat analogous to the brain in the computer. The term has been in...

AMD K10
The AMD Family 10h is a microprocessor microarchitecture by AMD. Though there were once reports that the K10 had been canceled, the first third-generation Opteron products for servers were launched on September 10, 2007, with the Phenom processors for desktops following and launching on November...

Thermal Design Power
The thermal design power , sometimes called thermal design point, refers to the maximum amount of power the cooling system in a computer is required to dissipate. For example, a laptop's CPU cooling system may be designed for a 20 watt TDP, which means that it can dissipate up to 20 watts of heat...
