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.

To find more results use this page :

(enter R710 or R720 in the "system" field).
