Intel Xeon E5-2650 

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.

It might also come to pass that some server motherboard manufacturers will end up supporting the DDR4-2133 at 3DPC, similar to some efforts made with Patsburg.

Low quality conversion loves faster individual cores, hence the W processor wins out due to its higher full-load frequency.

However, it's not a case of the Haswell's L3 cache being a lot worse: the 20MB L3 cache of the Xeon E5-2667 v3 is only slightly slower than the Xeon E5-2690 and is still faster than the Xeon E5-2697 v2 (30MB).

Of course, those kind of bandwidth numbers only matter for specific HPC benchmarks as the L3 cache (30-45MB L3) will take care of most of the requests.

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.
