Inquirer points out the SPEC Power results posted by AMD for Shanghai and Penryn (Xeon L5420) both at 2.5GHz.
AMD results for Shanghai is 731 versus 561 for Xeon.
SPEC Power results posted by others for the L5420 were higher, the SuperMicro results being 990, but not as close a system match as the 2 AMD results (Windows instead of Linux, and BEA vs Oracle).
Now SPEC Power is not my field, as I have never run it. Inquirer points out the different memory config. However in reading through the reports, AMD has the Xeon L5420 system power at 179, 197 and 279W for idle, 10% and 100% respectively. The SuperMicro result has 97, 108 and 174W respectively. I do not think 2 DIMMs will make up 100W, The difference in the SuperMicro result includes settings:
Adjacent Sector Prefetcher disabled in BIOS.
C1 Enhanced Mode enabled in BIOS.
3pin Server Mode enabled.
