Intel Xeon E7-8890 v3 

Released April, 2015
  • 2.5 GHz
  • Processing Cores

Despite the high core count, the E7-8890 v3 has its base frequency set at 2.5 GHz to yield a TDP of 165W.

Ofcourse since this is the LGA 2011-3 or Revision 3 or R3 socket, the CUPs can support upto 14 cores and both DDR and DDR4 Memory.

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.
Although the seller knows what he is doing, it would be interesting to see where the founder finds himself an R3 motherboard.
DDR4 memory is supported upto 2133 Mhz, after which the memory controller starts to over clock itself.
