For example, the on-die bus has been updated to include two fully buffered rings, a necessary addition to support the extreme core counts launching today.

Intel Announces Xeon E7 v3 Processors Based on Haswell-EX

by Scott Michaud |
www.pcper.com
The E7-8880L v3 is a low power version, relatively speaking, which will also contains eighteen cores that are clocked at 2.0 GHz.
The largest model is the E7-8890 v3, which contains eighteen cores fed by a total of 45MB in L3 cache.
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.
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.
