AMD Beats Intel in Power-Efficiency Study

Posted by CowboyNeal on from the bang-for-the-buck dept.

Ted Samson writes "AMD Opteron servers proved up to 15.2 percent more energy-efficient than those running Intel Xeon in a server-power-efficiency test performed by Neal Nelson and Associates, InfoWorld reports. That translates to annual electricity savings between $20.29 per server and $36.04 per server, depending on the workload, the study concluded. The benchmark tests were conducted on similarly configured 3GHz systems running Novell SUSE Linux, Apache2, and MySQL."

    Actually the power capacity of a supply WILL affect the power measured as even same amount of power output will be on different part of the efficiency curves even if component losses are identical. Power supplies tends to be most efficient from 1/3 to 2/3 of their power ratings.

    For a more scientific study, they should use the same power supply.
