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

by Scott Michaud |
www.pcper.com
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.
