Intel Xeon E3-1225 v3 

Released April, 2013
  • 3.2 GHz
  • Quad core
7.9 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.

The price difference between the 14 core model and the 16 core model is nearly $1000, making budgets and workloads being important factors in this decision.

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.

Intel Haswell-EP Xeon 14 Core Review: E5-2695 V3 and E5-2697 V3

by Ian Cutress |
The prevalence of multithreaded code is server and workstation environments make the frequency difference extremely important, especially when it comes to the types of workloads that have frequent memory delays and accesses.
If it happens in a core as part of the logic or caches, that core can be fused off and the die can sold as a lower core part.

Intel Haswell-EP Xeon 12 Core Review: E5-2650L V3 and E5-2690 V3

by Ian Cutress |
Similarly to the E5-2687W V3, the moment we hit a frequency the system does not like, it returns as a complete failed POST rather than a BSOD.
As part of this review we were able to source two E5-2650L V3 CPUs with a dual CPU motherboard and offer a more competitive analysis at 130-135W total TDP against the E5-2690 V3.

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.
