For our latest big procurement I measured (among other things) the actual power draw of all final candidates. One was a dual Opteron 2220 (2.8 GHz dual core part) which at idle/load scored 218W/301W this with 12 dims (24 gig) one sata drive and no IB. A 2nd vendor measured 230/315 for a very similar configuration. We did not test any intel 51xx, only 53xx (quad core). The 2.33 GHz 53xx (80W tdp if I remember correctly) did around 260W/350W (this with one drive and 8 fbdimms with a total of 32 gig). An IB board is typically <10W, Mellanox says that their LX single port DDR card is only 4W. Hope that helps a bit, Peter > Jon
