AMD has announced widespread availability of five new low-power 45nm Quad-Core AMD Opteron HE processors.

The chips are released at 55W ACP or 79W TCP respectively and are mostly targeted at low power, cost-saving data center technology. They will also see the light of day in eight server systems from HP. Rackable Systems will also have Quad-Core AMD Opteron HE processor-based servers available immediately and additional systems from global OEMs including Dell, Sun, and other solution providers are expected later this quarter.

The 45nm Quad-Core AMD Opteron HE processor, has speeds ranging from 2.1 to 2.3 GHz. AMD claims that  Server platforms based on these new AMD Opteron HE processors can offer up to 20 per cent lower idle power compared to similarly configured competing systems, helping cut energy costs without compromising any of the processor features of the standard power options.

Two new 45nm Quad-Core AMD Opteron SE processors (2.8 GHz) are now available for customers with the most performance-intensive datacenter workloads. These are designed for the 105W ACP/137W TCP thermal envelop.
