Intel Xeon E5 v4 Broadwell Buyers Guide (Parallel Performance)

Intel’s Xeon E5 v4 processors are available and there are lots of them! The changes from the v3 Haswell are mostly small clock changes and increases in core count. You can now get a E5-2699v4 with 22 cores. In a dual socket system that’s 44 cores to work with. If the programs you want to run scale well with thread count then that could be a great processor for you. However, if your parallel scaling is not near linear then it may not be the best value. We have a dynamic chart of performance based on Amdahl’s Law that may help you decide which processor is best for your uses.

Intel Xeon E5 v3 Haswell-EP Buyers Guide

The new Xeon E5 v3 Haswell processors are here, all 30+ of them! There is a bewildering variety of clock speeds, core counts, and power usage. There are processors in the new v3 familly ranging from the single socket E5-1620v3 with 4 cores at 3.5 GHz to the dual socket E5-2699v3 with 18 cores at 2.3GHz. How do you make a choice for a new system?!

How do these new processors perform when you programs parallel scaling is less than perfect?
