San Clemente chipset gives HP lead on energy efficiency

The January 30th 2008 batch of test results are in for SPECpower_ssj2008 energy efficiency benchmark and it looks like Hewlett Packard has claimed the energy efficiency lead with their newest low-cost 2U HP Proliant DL180 G5 server.  The secret to their success appears to lie in the selection of the Intel 5100 series "San Clemente" chipset.
