I want to buy a new server, and am contemplating a Dell R710 or the
newer R720. The R710 has the x5600 series CPU, while the R720 has the
newer E5-2600 series CPU.
For this the best data I've found (excepting actually running tests on
the physical hardware) is to use the SpecIntRate2006 numbers, which can
be found for both machines on the spec.org web site.
I think the newer CPU is the clear winner with a specintrate performance
of 589 vs 432.
It also has a significantly larger cache. Comparing single-threaded
performance, the older CPU is slightly faster (50 vs 48). That wouldn't
be a big enough difference to make me pick it.
The Sandy Bridge-based machine will likely use less power.
