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.

Nice stuff. Realy good to see them bringing power consumption down pr. Performance.WorldWithoutMadness - Tuesday, June 23, 2015 - link
Nice way to confuse people. Codename Yosemiteretrospooty - Tuesday, June 23, 2015 - link
Who would this confuse? Apple fans because of the OS witht he same codename?LOL. Believe me they don't know, or care... Most of them aren't even aware of what a "server" chip is, or even what a "server" is used for.

Rails developer checking in to remind you that a great chunk of the Rails community develop using OS X to deploy on Linux and hence is aware of "server chips". Even though you said that "most" Apple users don't know what a server chip is and that's accurate, the same could be said about Windows or even Linux common users. Stop patronizing.All being said, I agree with you. Who could possibly confound the Xeon D's codename coincides with OS X's 10.10 name?

First of all, your implication that apple fans don't know jack shit about servers is a broad generalization, and a stupid one at that.Second of all, anyone who knows enough to even consider buying a Xeon and a motherboard that supports it and the ECC memory, probably knows enough to not get confused. And plenty of mac users know what server chips are and what they're used for.
Nice trolling though.

That's not entirely true, but I will agree that people a lot of the people who use Apples( No discrimination intended) only continue to use Apple due to their lack of tech knowledge( like knowing Android is the king :) . And, yes, they probably won;t know what servers even are.jeffsci - Monday, June 29, 2015 - link
Geographic code names are the norm in the computing industry (I think because they cannot be copyrighted) and they end up being reused. For example, Intel Seattle is/was a motherboard and AMD Seattle is/was an ARM64 processor. See https://en.wikipedia.org/wiki/List_of_Intel_codena... https://en.wikipedia.org/wiki/List_of_Microsoft_co... etc. if you would like to look for more examples :-)RaiderJ - Tuesday, June 23, 2015 - link
Any places in the US that the motherboard is available for purchase? Quick checks looks like it's mostly sold out or otherwise unavailable?ats - Tuesday, June 23, 2015 - link
Availability comes and goes. Xeon D has been a big hit in the large scale deployment markets and they've been soaking up a lot of demand for it, both bare and combined on motherboards like the supermicro offerings severely limiting retail availability. But it is available in retail but quantities are limited. Quite a number of people over at servethehome have gotten their hands on them. If you want one, you'll likely have to keep checking the major sites like newegg, amazon, et al for them to come back in stock. Retail boards are generally in the $800-1000 range atm (basically going for full list but then again bare motherboards with 10gbe tend to go for 600+ so its still a good buy and simple new 10gbe cards tend to go for $300-500).ToTTenTranz - Tuesday, June 23, 2015 - link
How come they call this a SoC if there's no integrated module to drive even a simple display, and they apparently need a discrete PCIe graphics card for that D-SUB output?
