Intel Xeon E3-1220 v5 

Released October, 2015
  • 3 GHz
  • Quad core

Clock speed has clearly been traded in for more cores in most of server SKUs.

It is clear that Intel has improved AVX efficiency quite a bit.

Intel Xeon E5 Version 3: Up to 18 Haswell EP Cores

by Johan De Gelas |
However, it's not a case of the Haswell's L3 cache being a lot worse: the 20MB L3 cache of the Xeon E5-2667 v3 is only slightly slower than the Xeon E5-2690 and is still faster than the Xeon E5-2697 v2 (30MB).
Of course, those kind of bandwidth numbers only matter for specific HPC benchmarks as the L3 cache (30-45MB L3) will take care of most of the requests.

Intel Broadwell-EP Xeon E5 v4 Because Why Not?

by Scott Michaud |
They claim it will be Intel's first 14nm Xeon processor which obviously suggests that it will not be preceded by Broadwell in the lower performance server categories.
Intel will apparently allow Haswell and Broadwell to give off a little more heat than their predecessors.
