Benchmark Configuration and Methodology
All of our testing was conducted on Ubuntu Server 14.04 LTS. Admittedly, that might seem like an old distribution to some of our readers, but enterprises prefer stability and support over the latest software. We did upgrade this distribution to the latest release (14.04.4), which gives us more extensive hardware support.
To make things more interesting, we tested 4 different SKUs and included the previous generation Xeon E5 v3s, the Xeon E5-2697v2 (high end Ivy Bridge EP), and the E5-2690 (high end Sandy Bridge EP). We even included the Xeon X5680 for comparison reasons. The Xeon E5-2695 v4 is interesting to compare to the Xeon E5-2699 v3 as it has the same core count and more or less the same clockspeed. That way we could quantify the improvement that the Broadwell core offers over the Haswell core.
Last but not least, we want to note how the performance graphs have been color-coded. Orange is the latest generation (v4), dark blue the previous one (v3), and light blue is the generation that the current (v4) is (arguably) supposed to replace (Xeon E5 v1).

Other Notes
Both servers are fed by a standard European 230V (16 Amps max.) power line. The room temperature is monitored and kept at 23°C by our Airwell CRACs.

The article says TSX-NI is supported on the E5, but if one looks at Intel ARK, it say it's not. Do the processors say they support TSX-NI? Or is this another one of the things which will be left for the E7?JohanAnandtech - Friday, April 1, 2016 - link
Intel's official slides say: "supports TSX". All SKUs, no exceptions.Oxford Guy - Thursday, March 31, 2016 - link
Bigger, badder, still obsolete cores.patrickjp93 - Friday, April 1, 2016 - link
Obsolete? Troll.Oxford Guy - Tuesday, April 5, 2016 - link
Unlike you, propagandist, I know what Skylake is.benzosaurus - Thursday, March 31, 2016 - link
"You can replace a dual Xeon 5680 with one Xeon E5-2699 v4 and almost double your performance while halving the CPU power consumption."I mean you can, but you can buy 4 X5680s for a quarter the price of a single E5-2699v4. It takes a lot of power savings to make that worthwhile. The pricing in the server market's always seemed weirdly non-linear to me.

Presumably, it's not just about TCO. Space is at a premium in a datacenter, and so being able to fit more performance per sq ft also warrants a higher price, just like how notebook parts have historically been more expensive than their desktop equivalents.ShieTar - Friday, April 1, 2016 - link
But you don't get 4 1366-Systems for the price of one 2011-3 System. Depending on your Memory, Storage and Interconnect Needs, even two full Systems based on the Xeon 5680 may cost you more than one system based on the E5-2699 v4. One less Infiniband-Adapter can easily save you 500$ in Hardware.And you are not only halving the CPU power consumption, but also the power consumption of the rest of the system that you no longer use, so instead of 140W you are saving probably at least 200W per System, which can already add up to more than 1k$ in electricity and cooling bills for a 24/7 machine running for 3 years.
And last, but by no means least, less parts means less space, less chance for failure, less maintenance effort. If you happily waste a few hours here or there to maintain your own workstation, you don't do the math, but if you have to pay somebody to do it, salaries matter quickly. With an MTBF for an entire server rarely being much higher than 40.000, and recovery/repair easily taking you a person-day of work, each system generates about 1.7 hours of work per year. Cost of work (it's more than salaries, of course) probably comes up to 100$ for a skilled technical administrator, thus producing another 500$ over 3 years of added operational cost.
And of course, space matters as well. If your data center is filled, it can be more cost effective to replace the old CPUs with new expensive ones, rather than build a new facility to fill with more old Systems.
If you add it all up, I doubt you can get a System with an Xeon 5680 and operate it over 3 years for anything below 20.000$. So going from two 20.000$-Systems to a single 24.000$ Dollar System (because of an extra 4000$ for the big CPU) should save you a lot of money in the long run.

Where do you get your pricing info from? I can not imagine that server vendors still sell X5680s.extide - Friday, April 1, 2016 - link
Yeah, if you go used. No enterprise sysadmin worth his salt is ever going to put used gear that is not in warranty, and in support into production.
