Intel Xeon E3-1285L v4 

Released April, 2015
  • 3.4 GHz
  • Quad core
9.7 Out of 10

Sure, the AMD solution will be available over a year earlier and cost a fraction of the multi-thousand-dollar server processor, but it is somewhat ridiculous to think that a CPU has the theoretical performance available to software render the equivalent of Battlefield 4's medium settings without a GPU (if the software was written with said rendering engine, which it is not... of course).

TDPs will be the same as Haswell-EP which range from 70W to 145W for server parts and from 70W to 160W for workstations.

Intel Launches Xeon E7 v4 Processors

by Scott Michaud |
The E7-8XXX line can be run in an eight-socket motherboard, while the E7-4XXX models are limited to four sockets per system.
With Intel's Xeon naming scheme, the leading number immediately after the E7 in the product name denotes the number of CPUs that can be installed in a multi-socket system.

Intel Broadwell-EP Xeon E5 v4 Because Why Not?

by Scott Michaud |
They claim it will be Intel's first 14nm Xeon processor which obviously suggests that it will not be preceded by Broadwell in the lower performance server categories.
Intel will apparently allow Haswell and Broadwell to give off a little more heat than their predecessors.
