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.

This is a great test to use to rate the system speed; it also works as a stress test to see how well the system cooling is performing.

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.
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.
Although the seller knows what he is doing, it would be interesting to see where the founder finds himself an R3 motherboard.
DDR4 memory is supported upto 2133 Mhz, after which the memory controller starts to over clock itself.
