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.

Yes, but it's still bad marketing. -D is associated with inferior, overly hot, bad performing Intel chips.IanHagen - Tuesday, June 23, 2015 - link
Certainly. From a marketing standpoint it's a pretty poor choice. I agree with wussupi, E4 would haven been a far better name.karpodiem - Tuesday, June 23, 2015 - link
does anyone know where to buy these online? I'm looking for just the board/processor, model # 'X10SDV-TLN4F'All these random/small Supermicro resellers are selling it now, based on some Google searches. They're marking it up in price by at least a hundred bucks, because availability is limited. Anyone know when Newegg might get it in stock?
Looking to do a FreeNAS build - this board + IBM M1015 card in an ATX motherboard (6x4TB drives in RAIDZ2).

The TLN4F is the one in most demand and almost no place is able to keep it in stock. There are multiple places that will order it for you for ~1K but wait times can be anywhere from 1 week to 1 month.Jon Tseng - Tuesday, June 23, 2015 - link

Dude... You really want to have a look at the latest ThunderX parts or the X-Gene 16nm shrinks before you start making unwise statements like that. These aren't waiting around for A57 they are custom ARM architecture designs. Per core performance might not be as hot as Xeon but once you start to throw 48 cores on a die I wouldn't quite call that "at best competing with Avaton".

X-Gene is in the article, any further shrinks are still entirely vapor. ThunderX isn't currently available is is likely to have significantly worse per core performance than Atom C2k series and worse than A57. All the cores in the world don't do jack if the ST isn't there. And ST performance IS a barrier even in scale out. For general scale out, C2750 was found fairly wanting because of the ST performance, and neither X-Gene nor ThunderX even compete with C2750 in ST performance...

He said "currently". The X-Gene 16nm cores might offer some competition who knows - but those are X-Gene 3 whereas you can't even buy anything with X-Gene 2 28nm ones right now... Likewise, ThunderX servers have been announced, but I haven't seen any reviews yet.name99 - Tuesday, June 23, 2015 - link
Look at the ThunderX parts HOW? Cavium releases fsck-all information about them. No-one knows if they are even OoO, how wide they are, etc.Yes, there are 48 cores on a SoC; and presumably they will do well for tasks like memcached that like lots of low-performance parallelism. But right now, we have ZERO evidence that a ThunderX part is a better single-threaded core than A57, let alone that it's comparable to Broadwell.
