Yesterday on the Earth Day, AMD introduced latest generation energy efficient Opteron processor consuming only 40W of power. The 45nm Quad-Core AMD Opteron EE processor with AMD’s lowest x86 quad-core server power band is designed for very dense data center environments such as those built for cloud computing, web serving, or other highly dense environments.

The Quad-Core AMD Opteron EE processor adds significant power efficiency improvements over the Quad-Core AMD Opteron HE processor within the same platform with a 13 percent reduction in platform-level power consumption and up to a 14 percent reduction in processor power at idle.

At the same performance level, the new EE processor delivers up to 62 percent improved performance-per-watt over the previous generation.

AMD also announced new, high performing processors available in the HE, standard, and SE power bands, as well as support for HyperTransport 3 technology and a new fine-tuning feature called AMD Core Select, which enables IT managers to turn off one or more cores, helping them to fine tune their hardware for their specific operating conditions and workloads.
