In similarly configured platforms1, the enhanced Quad-Core AMD Opteron™ 55W processor (“Shanghai”)-based platform offers up to a 46 percent overall performance to power ratio advantage over the 50W processor-based competitive platform. For these platforms, the enhanced Quad-Core AMD Opteron processor Model 2381 HE-based platform only used 140W at Active Idle compared to the Quad-Core Intel Xeon processor Model L5420-based platform using 179W at Active Idle. The enhanced Quad-Core AMD Opteron processor Model 2381 HE-based platform had a SPECpower_ssj™2008 result of 819 overall ssj_ops/Watt (316,318 ssj_ops @ 100% target load). The Quad-Core Intel Xeon processor Model L5420-based platform had a SPECpower_ssj™2008 result of 561 overall ssj_ops/Watt (267,804 ssj_ops @ 100% target load).
1These similarly configured platforms use the same power supply, the same disk drive, and the same NIC. The Quad-Core AMD Opteron processor-based platform uses 8 DDR2-800 DIMMs of 2GB each. The Quad-Core Intel Xeon processor-based platform uses 8 DDR2-667 Low-Power FB-DIMMs of 2GB each.
