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.

So, I was thinking last night, that this chip is THE PERFECT enthusiast chip! All Intel needs to do is release an unlocked and socketed version (although that would be complex because there is currently no platform for it ...) although if we could get at least an unlocked version on an enthusiast style board it would be awesome.Think about it:
8 Broadwell cores -- Great!
12MB L3 -- Great!
24 Lanes PCIe 3.0 -- More than 16 or even skylakes rumored 20, pretty good. You could do things like 16x + 8x, or 8x + 8x + 4x + 4x (the two 4x being m.2 ssd's) which would support CF or SLI quite well and some fast ssd's.
2ch DDR4 -- plenty for gaming and most enthusiast applications
Dual 10GbE -- Just added Gravvy here, but would def help adoption of 10g in the enthusiast realm.
COME ON INTEL!!

Also, I forgot to add:This would be a great intermediate between the current regular consumer stuff (LGA 115x) and HPDE (LGA 2011x) -- A lot of people really see the LGA 2011 platform as overkill, even for enthusiasts, and it gets so expensive, with quad channel ddr4 and all that. This chip just seems to make so much sense. Now if intel priced it no more than the $500 mark, that would be awesome. Imagine, if AMD was more competitive, we might actually have that5 scenario.... Hopefully Zen is just great!

Intel's tray price for this chip is listed at $199 for the 4-core and $581 for the 8-core. The price for the CPU+motherboard is almost $1K for the 8 core. which indicates the problem is not in the price of the chip itself.If you want cheap and low power consumption, I'd direct you to the S1150 platform with Xeon E3 V3 "L" series (13-45W) processors.

For a home machine, small server, workstation, or similar the Xeon D 1520 looks even better. Faster clock, 1/3rd the price, same maximum ram, ecc, etc. Sure it's got 4 cores/8threads instead of more, but for many use cases that's not a big limitation. In quite a few cases spending the $400 different on RAM or SSDs will make a bigger difference.hifiaudio2 - Thursday, June 25, 2015 - link
Where can you get a 1520? Google searching is not finding anything for sale...hifiaudio2 - Thursday, June 25, 2015 - link
If I cannot find the 1520 for sale, what is the best bang for the buck i3 and MB combo (want to use ECC ram as well) for a Media server/transcode/nas? Low TDP, etc..jaziniho - Thursday, June 25, 2015 - link
Any word on whether HP plan to make a Moonshot cartridge featuring Xeon D? the 45W TDP seems to match up with some of the previous chips they have used.jeffsci - Monday, June 29, 2015 - link
Why do the results use a variety of OSS compilers? For an Intel Xeon processor, the Intel compilers are the most reliable. Is Open64 actively developed for Intel processors? And switching from GCC 4.8 to 4.9 with different flags...how is this even remotely scientific?needforsuv - Saturday, July 11, 2015 - link
so they just done to the 'regular' 4/8 i7/e3 what they did to the C2D in making the C2Q but more sophisticated I like it now wheres that lga 115x 8 coretabascosauz - Sunday, July 19, 2015 - link
I hope that Mr. de Gelas will continue to learn and improve as a writer, because the grammar in this article is, in numerous places, rather iffy and AT has traditionally excelled in delivering detailed, grammatically correct content.
