  • Quad core
8 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 Broadwell-EP Xeon E5 v4 Because Why Not?

by Scott Michaud |
www.pcper.com
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.
