Multi-Threaded Integer Performance
Next we run the same workload in several active instances to see how well the different CPUs scale. The Xeon E5 and Xeon D should finally be able to show off their higher core counts.
The Xeon D scales well: performance is multiplied by 8. It is interesting to note that it delivers 82% of the raw integer processing power of the low power Xeon E5, which has 50% more cores and a 44% higher TDP (65W).
We did not test the Xeon E3-1265L v3 (45 W), but the 3.1 GHz chip will end up between the E3-1265L v2 and E3-1240 v3 (3.4 GHz), it will probably score something like 19000. The Xeon D delivers thus no less than 50% more raw processing power at the same TDP, while integrating more functionality. This should further drive down the total power a server uses. This really shows what an excellent improvement the Xeon D is if you can use the 16 threads.
The decompression benchmark tell us the same story as the compression test: the Xeon D delivers.

this is the reason why Intel focuses on mobile, it benefits their server cpus too.the 14nm process is the one to thank for these massive improvements. Samsung also has 14nm and the S6 Exynos is in similar achievement

I disagree, the Exynos is no where close to a similar achievement.Granted it is doing better than Qualcomm's equivalent at the moment.
But I'm also faster than a fat man with a broken leg running on a hot and humid day.

Still, these 14nm SoCs are the best in their class as they pack more cores while using less power.LukaP - Thursday, June 25, 2015 - link
Just a note, Samsung's (and TSMC's 16nm FF(+) process isnt really 16nm entirely. The interconnects are still 28nm making it not nearly as dense as intel's 14nm, as well as being more leaky. IIRC their density and leakage can be compared to intels 22nm TriGate in the times of Ivy Bridgenils_ - Tuesday, June 23, 2015 - link
Few questions:1. Why did you disable x2apic?
2. Did the Large Page allocation in the Java Benchmark actually work? It can be a bit tricky some times and then falls back to 4KiB pages
3. What were the JVM settings for elasticsearch?

1. Was out of the box disabled. I have to admit I did not check that option. Performance impact should be neglible though.2. I have no monitored that, but there was a performance impact if we disabled it.
3. ES_heap_size = 20 G; otherwise standard ES settings

Wow, that is still quite pricey here. For the price of the SuperMicro tower you can actually get a 1U 2S Xeon E5 system with one socket equipped and some memory. I'd really love to replace my home server (running on Core i5 rather than Xeon E3 for efficiency reasons, those C chipset suck balls) with one of those systems if they can make them efficient and quiet.hifiaudio2 - Tuesday, June 23, 2015 - link
Two questions:1. How does the Xeon D compare to the c2700 series for a home NAS that will also serve as an Emby server and HDHR DVR (when that software is available). Could be one or two 1080p transcodes going on at the same time at most. Usually no transcoding if I am using Kodi or something that can natively play back the file, but for remote viewing or random uses over the network, some transcoding by Emby could be required -- if you are not familiar with Emby think of the same thing using Plex. So would the extra power of the Xeon D be of use to me, or is the 8 core c2750 plenty for the aforementioned use case?
2. If I do go with this unit, which dimms specifically does it use? The Supermicro c2750 board takes laptop style dimms. What does this take?

I can answer 2: see the picture here: http://www.anandtech.com/show/9185/intel-xeon-d-re... RDIMMs or UDIMMS (= basically "normal" DDR-4) will do.hifiaudio2 - Tuesday, June 23, 2015 - link
Thanks.. So this ram:?http://www.amazon.com/Crucial-PC4-2133-Registered-...
And what is the SR x4 / DR x8 difference in the two choices for the 8gb sticks?
