Intel Xeon E3-1275L v3 

Released May, 2014
  • 2.7 GHz
  • Quad core

It turns out that when you have up to 18 cores on a single die, this ability is crucial to supporting maximum performance on a wide array of compute workloads and to maintain power efficiency.

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

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.
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.
This chart shows how an aggressor VM can start to degrade performance until cache monitoring detects this, partitions the cache, and restores packet performance.
The core will slow during the execution of the AVX instruction in order to maintain TDP limits, which may cause the frequency to drop.
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.
