I would expect the dual-die approach with the split memory controllers to make it a bit slower than Haswell-E (and to provide some benefit from messing about with NUMA controls and MPI), but you have an awful lot of cores to drive those memory controllers.

(I won't be buying a new machine until March, but I notice the Intel lots-of-core-Xeons-at-less-absurd-price range has now officially appeared)
