Benchmark Configuration
All tests were done on Ubuntu Server 14.04 LTS (soon to be upgraded to 15.04). Aside from the SuperMicro Xeon-D system, we also have the ASRock Rack C2750D4I (eight core Silvermont), a Xeon E3-1200 v3 system, a Xeon E3-1200 v2 system, a 1P Xeon E5-2600L v3 and a HP Moonshot cartridge based system. We tested the HP Moonshot cartridges remotely.
Supermicro's 5028D-TN4T
| CPU | Xeon D-1540 2.0 GHz |
| RAM | 4x16GB DDR4-2133 |
| Internal Disks | Samsung 850 Pro 128 GB |
| Motherboard | SuperMicro X10SLD-F |
| PSU | FSP250-50LC (250 W, 80+ Bronze) |
Below you can find most of the CPU settings in the BIOS:
ASRock's C2750D4I
| CPU | Intel Atom C2750 2.4 GHz |
| RAM | 4x8GB DDR3-1600 |
| Internal Disks | Samsung 850 Pro 128 GB |
| Motherboard | ASRock C2750D4I |
| PSU | Supermicro PWS-502 (80+) |
The Xeon D is not a replacement for the Atom C2000. Although the Xeon D is also a SoC, the Atom C2000 remains Intel low power options for microservers. Of course, we want to know how much power you save, and how large the performance trade-off is.
Intel's Xeon E3-1200 v3 – ASUS P9D-MH
| CPU | Intel Xeon processor E3-1240 v3 3.4 GHz Intel Xeon processor E3-1230L v3 1.8 GHz |
| RAM | 4x8GB DDR3-1600 |
| Internal Disks | 1x Samsung 850 Pro 128 GB |
| Motherboard | ASUS P9D-MH |
| PSU | Supermicro PWS-502 (80+) |
As the Xeon D is limited to 2 GHz (2.6 GHz turboboost), higher clocked Xeon E3s might still make sense where single threaded performance is a major concern. The Xeon E3-1230L was included as a low power alternative, although we wonder it still make sense, considering that the Xeon E3 needs a separate 1-4W chipset (C220).
Intel's Xeon E3-1200 v2
| CPU | Intel Xeon processor E3-1265L v2 |
| RAM | 4x8GB DDR3-1600 |
| Internal Disks | 1x Intel MLC SSD710 200GB |
| Motherboard | Intel S1200BTL |
| PSU | Supermicro PWS-502 (80+) |
The previous generation low power Xeon E3.
Intel's Xeon E5 Server – "Wildcat Pass" (2U Chassis)
| CPU | One Intel Xeon processor E5-2650L v3 (1.8GHz, 12c, 30MB L3, 65W) |
| RAM | 128GB (8x16GB) Samsung M393A2G40DB0 (RDIMM) |
| Internal Disks | 2x Intel MLC SSD710 200GB |
| Motherboard | Intel Server Board Wildcat Pass |
| PSU | Delta Electronics 750W DPS-750XB A (80+ Platinum) |
Although our E5 server is not comparable to the other systems, it important to gauge where a low power E5 model would land. We like to understand when it make sense to invest more money in an Xeon E5 system, and here we only use one Xeon. Note that this system also requires power from a separate PCH.
HP Moonshot
More info about this configuration can be found in our previous article about micro server SoCs.
We tested two different cartridges: the m400 and the m300. Below you can find the specs of the m400:
| CPU/SoC | AppliedMicro X-Gene 2.4 |
| RAM | 8x 8GB DDR3 @ 1600 |
| Internal Disks | M.2 2280 Solid State 120GB |
| Cartridge | m400 |
And the m300:
| CPU/SoC | Atom C2750 2.4 |
| RAM | 8x 8GB DDR3 @ 1600 |
| Internal Disks | M.2 2280 Solid State 120GB |
| Cartridge | m300 |
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. We use the Racktivity ES1008 Energy Switch PDU to measure power consumption in our lab. We used the HP Moonshot ILO to measure the power consumption of the cartridges.

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.
