On Monday, Intel plans to start shipping a new version of its quad-core Xeon processor that will consume just 50 watts under peak loads.
The company outlined plans for the chips last week at a briefing for the press in San Francisco. The two chips are a lot cooler than Intel's other quad-core processors, which are rated at 80 watts and 120 watts, allowing them to be used in denser servers.
Advanced Micro Devices also ships a line of energy-efficient server processors that are rated at 68 watts of power consumption under maximum conditions. Performance-per-watt is all the rage these days in the server market as IT departments realize the impact on their electric bills by the power-hungry servers of a few years ago.
