NOTE: 4 nodes report 16 processors because they run in hyperthreading mode. So 32 extra processors show up on a scan of /proc/cpuinfo.
The E5430 is a member of the Harpertown series, released in November 2007. Power consumption for the 45 nm chips is 80W. Front side bus runs at 1.3 GHz. The series runs up to 3.4 GHz at 150W, so I expect the chip to be rather stable at 2.66 GHz and 80W. The L2 cache has 6MB.
The E5520 is a member of the Gainestown series, released in March 2009. Power consumption for the 45 nm chips is 80W. Front side bus runs at 1.0 GHz. The L2 cache has 1MB but has an 8MB L3 cache.
The X5650 is a member of the Gulftown series, released in March 2010. Power consumption for the 32 nm chips is 95W. Front side bus runs at 1.3GHz. The L2 cache has 6x256 kB but has 12MB L3 cache.
