 AMD claims the ACP rating includes the power consumption when running several benchmarks, including 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.
