Intel Xeon E5-2640 v3 

Released July, 2014
  • 2.6 GHz
  • Octa core
5.3 Out of 10

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.

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.
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.
