It turns out that when you have up to 18 cores on a single die, this ability is crucial to supporting maximum performance on a wide array of compute workloads and to maintain power efficiency.

This is a great test to use to rate the system speed; it also works as a stress test to see how well the system cooling is performing.

Eighteen-core Xeon E7 v3 Based on Haswell-EX in Q2'15

by Scott Michaud |
If that is not enough cores, then you can pick up an eight-socket motherboard and load it up with multiple of these.
While Ivy Bridge-EX was available with up to 15 physical cores per processor, double that with HyperThreading, Haswell-EX is increasing that to 18, or 36 simultaneous threads with HyperThreading.
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.
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.
