Intel Xeon E7-8880 v3 

Released April, 2015
  • 2.3 GHz
  • Processing Cores

Low quality conversion loves faster individual cores, hence the W processor wins out due to its higher full-load frequency.

Intel Announces Xeon E7 v3 Processors Based on Haswell-EX

by Scott Michaud |
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.

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

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.
It might also come to pass that some server motherboard manufacturers will end up supporting the DDR4-2133 at 3DPC, similar to some efforts made with Patsburg.
Low quality conversion loves faster individual cores, hence the W processor wins out due to its higher full-load frequency.
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.
