Supermicro's Xeon D Solution: X10SDV-12C-TLN4F
The top tier server vendors seem to offer very few Xeon D based servers. For example, there is still no Xeon D server among the HP Moonshot cartridges as far as we know. Supermicro, on the other hand, has an extensive line of Xeon D motherboards and servers, and is basically the vendor that has made the Xeon D accessible to those of us that do not work at Facebook or Google.
The first board we were able to test was the mini-ITX X10SDV-12C-TLN4F. It is a reasonably priced ($1200) model, in the range what the Gigabyte board and Cavium CN8880 -2.0 will cost (+/- $1100).
The Xeon D makes six SATA3 ports and two 10GBase available on this board. An additional i350-AM2 chip offers 2 gigabit Ethernet ports. The board has one PCI-e 3.0 x16 slot for further expansion. We have been testing this board 24/7 for almost 3 months now. We have tried out the different Ethernet ports and different DDR-4 DIMMS: it is a trouble-free.
The one disadvantage of all Supermicro boards remains their Java-based remote management system. It is a hassle to get it working securely (Java security is a user unfriendly mess), and it lacks some features like booting into the BIOS configuration system, which saves time. Furthermore video is sometimes not available, for example we got a black screen when a faulty network configuration caused the Linux bootup procedure to wait for a long time. Remote management solutions from HP and Intel offer better remote consoles.

I think AMD themselves admitted that the Opteron X1100 was for testing the waters, with K12 being the first proper solution, but that was delayed to get Zen out of the door. I imagine that both products will be on sale concurrently at some point, but even with AMD's desktop-first approach for Zen, it will probably still come to the server market before K12 (both are due 2017).junky77 - Thursday, June 16, 2016 - link
still, quite strange, no? AMD is in the server business for years. I'm not talking about their ARM solution only, but their other solutions seem to be less interesting..silverblue - Thursday, June 16, 2016 - link
I am looking forward to both Zen and K12; there's very little chance that AMD will fail with both.name99 - Wednesday, June 15, 2016 - link
" It is the first time the Xeon D gets beaten by an ARM v8 SoC..."The Apple A9X in the 12" iPad Pro delivers 40GB/s on Stream...
(That's the Stream built into Geekbench. Conceivably it's slightly different from what's being measured here, but it delivers around 25GB/s for standard desktop/laptop Intel CPUs, and for the A9 and the 9" iPad's A9X, so it seems in the same sort of ballpark.)

Fantastic article as always Johan. Thank you so much for your very informative articles. I can only imagine how much time and effort writing this article took. It is very much appreciated.The first good showing by an ARMv8 server. Nearly 5 years later than expected, but they are getting there. This thing was still produced on 28 HKMG. Give it one more year, a jump to 14nm, and a more mature software ecosystem, and I think the Xeons might finally have some competition on their hands.

Thank you, and indeed it was probably the most time consuming review ... since Calxeda. :-)Yes, there is potential.

Even if the ThunderX is half the price of equivalent Xeon, I would still buy Intel Xeon instead. This isn't Smartphone market. In Server, The cost memory and Storage, Networking etc adds up. Not only does it uses a lot more power in Idle, the total TCO AND Pref / Watts still flavours Intel.There is also the switching cost of Software involved.
And those who say Single Core / Thread Performance dont matter have absolutely no idea what they are talking about.
As far as I can tell, Xeon-D offers a very decent value proposition for even the ARM SoC minded vendors. This will likely continue to be the case as we move to 10nm. I just dont see how ARM is going to get their 20% market share by 2020 as they described in their Shareholder meetings.

If you have to switch software on your severs because you switch architecture you are doing something wrong and are far too dependent on proprietary products. I'm being a bit facetious here but the only reason architecture should limit you is you are using Microsoft products or are in a highly specialized computing field. Linux should dominate your general servers.kgardas - Friday, June 17, 2016 - link
Even if you are on Linux, still stack support is best on i386/amd64. Look at IBM how it throws a lot of money to get somewhere with POWER8. ARM can't do that, so it's more on vendors to do that and they are doing it a little bit more slowly. Anyway, even AArch64 will mature in LLVM/GCC tool chain, GNU libC, musl libC, linux kernel etc but it'll take some time...tuxRoller - Thursday, June 16, 2016 - link
Aarch64 has very limited conditional execution support.http://infocenter.arm.com/help/index.jsp?topic=/co...
