Intel Xeon E3-1225 v5 

Released October, 2015
  • 3.3 GHz
  • Quad core

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

The previous Ivy Bridge-EX flagship had 4.31 Billion transistors configured on a 541mm2 so its easy to tell that the Haswell-EP takes die size and transistor count to a new level.

This chart shows how an aggressor VM can start to degrade performance until cache monitoring detects this, partitions the cache, and restores packet performance.
The core will slow during the execution of the AVX instruction in order to maintain TDP limits, which may cause the frequency to drop.
The previous Ivy Bridge-EX flagship had 4.31 Billion transistors configured on a 541mm2 so its easy to tell that the Haswell-EP takes die size and transistor count to a new level.
The Xeon E5-2600 V3 lineup is going to be aimed at the HPC server and workstation market featuring 23 E5-2600 V3 SKUs including the flagship Xeon E5-2699 V3 which boasts 18 Cores, 36 threads, 45 MB of L3 cache and a high price of $4115 US.

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.
For a workstation or server builder, in the 2S market, Haswell-EP offers an unmatched combination of performance and features.
Obviously the efficiency improvements that you get with AVX code will more than make up for the clock speed differences.
