Intel's Haswell NUC: D54250WYK UCFF PC Review
by Ganesh T S on January 3, 2014 4:25 PM ESTHardware and Setup Impressions
The Intel D54250WYK, unlike other off-the-shelf PCs, needs some components in order to complete the build. It is a barebones machine, in the sense that the power cord, RAM, storage as well as WLAN card need to be supplied in addition to the operating system. For the cost price, the user gets the motherboard (including CPU) and chassis, as well as a 65W (19V / 3.43A DC) adapter. The unit, however, has wired pigtail connections to the chassis sides for acting as the antennae for a WLAN card. The power cord needed is a C6 type that plugs into the power adapter's C5 type connector. The 3-plug C6 connector is also known as a cloverleaf connector. It does keep costs for Intel down, but it would have been really nice to localize this component to the country of sale. The kit also comes with a VESA mounting bracket.
Building the NUC is incredibly simple. There are four screws that hold the chassis together and removing them gives access to the motherboard. From here the end user can install up to two 8GB DDR3 SO-DIMMs. The bottom mini-PCIe slot accepts a half height card (perfect for WiFi) while the top slot can take a full height card or an mSATA drive. The antenna pigtails for WiFi are already routed to the appropriate spot inside the chassis.
Intel sent along its mSATA SSD 530 (180GB), which is a SandForce based mSATA drive using 20nm MLC IMFT NAND. SandForce controllers work very well in mSATA form factors since they don't require any external DRAM. For the RAM, we have 2x 4GB CT51264BF160B SODIMMs from Crucial. Handling the WLAN side of the equation is the 7260HMW, Intel's dual band 2T 2R 802.11ac mini-PCIe card solution.
The soldered down CPU (Intel Core i5-4250U with the HD5000 IGP) and the fan / cooling system are on the other side of the motherboard, and not visible in the pictures above. On the same side, we have a HTPC header (with HDMI CEC) on the side of the CMOS battery (referred to as the 'custom solutions header' in Intel's technical documentation for the product). In addition to the mSATA port, we have a SATA port and a SATA power connector as well as a dual-port internal USB 2.0 header. The Nuvoton NCT5577D embedded controller acts as a hardware monitoring subsystem. The motherboard also has a CIR sensor in the front panel.
A view of the assembled system is also provided in the gallery above. One of the points to note is the presence of the thermal pad on the bottom cover right below the SSD / WLAN stack. In the first revision of the NUC, Intel faced some heat for messing up the thermals. In particular, high temperatures causes the SSD to stop working. These temperatures were the result of either high disk activity or heavy WLAN traffic. A thermal pad solution was provided for the original NUC after release of the product. With the Haswell NUC, the thermal pad solution comes pre-integrated. The fan speeds also seem to be a bit on the higher side throughout usage. Consumers used to fanless PCs are definitely going to be a bit upset with the constant hum from the unit, but we do have passive cooling solutions from third-party vendors (at the cost of system size).
The choice of components in our build have an approximate cost breakdown for the hardware as below. It is possible to hit lower price points with judicious choice of DRAM and SSD capacity.
| Intel NUC D54250WYK Build | ||
| Component | Price | |
| Chassis / CPU / Motherboard / PSU | Intel D54250WYK | $375 |
| Memory | Crucial CT51264BF160B 2x4 GB Kit | $96 |
| SSD | Intel mSATA SSD 530 | $183 |
| WLAN | Intel 7260HMW Dual Band 802.11ac | $26 |

| Total | $680 | |
On the software side of things, Windows 8 Professional x64 was installed without any hiccups. All necessary drivers were available on Intel's website. In addition to the host of benchmarking programs, we installed the Netflix Windows 8 app for evaluating streaming aspects. For the HTPC-related section, we installed MPC-HC v1.7.1 and madVR v0.86.11. Many users prefer XBMC as a one-stop interface for all HTPC activities. Some benchmarks were also run using XBMC v12.3.

Well if you can kindly point us to an arm equipped device similar in size, with the same kind of ports, that actually runs win8 and is available, by all means post the link. Until then, you can hypothetically speaking all you want.lhl - Friday, January 17, 2014 - link
Yeah, I'm going to need to call BS on that. I assume that you haven't actually tried using those ARM SoC boards. I've tested most of the "high performance" ones (ODROID-X2 (Exynos 4), Samsung Chromebook (Exynos 5), Wandboard and UDOO (i.MX6 Quad)) w/ Ubuntu. First of all, cost on those are ~$150 w/ cases/power etc, so far from 1/5th the price (that's w/ soldered-in not-enough RAM and no storage). And second, the performance and software compatibility (anything from uBoot issues, to X11 drivers, to Flash Player) make them far less than ideal for general purpose usage.The ARM SoCs make for great embedded boards - TDP is great and the IPU/VPU on the i.MX6 is really interesting, but a good experience for Jane User? No way.
For general computing work, the i5 may be overkill, but a 1037u BRIX retails for $170 (+$40 for a 4GB SODIMM) which is probably where I'd start.

After trying the Steam In Home Streaming beta, I think the market for such machines as a secondary gaming station for PC gamers will increase.. if you have a solid gaming machine on the same network, this is all you'd need for playing those games on your TV at full fidelity.asliarun - Friday, January 3, 2014 - link
AT and Ganesh, thanks once again for an excellent review. I have a couple of questions and a suggestion:Q1. I am planning to build an audio server (optical or usb out from the PC - feeding to the rest of my stereo chain - Audio GD DAC acting as a DAC and preamp, Parasound power amp, and floorstanders). The NUC seems to be the ideal form factor for an audio server. Do you have any thoughts on this? Do you test audio quality (specifically stereo - not gaming audio) during your review and tests? I'm actually not planning to use the DAC of the onboard sound so that actually would not be an issue for me.
Q2. Another option I have been mulling over is to build a multi-purpose "steam box" kind of a device - that will let me run this SFF PC as an audio server, as an HTPC with XBMC, and will also let me do light to mid-level gaming with Steam big picture. I was actually waiting for Kaveri which I think will actually be more viable - but am not sure how well Haswell's integrated graphics stand up with something like Kaveri or even a graphics card. Especially with thermals and throttling in mind. What are your thoughts on the viability of the NUC in this regard? Do you have any pointers on what one should look at - considering that it should also be a small form factor (shoebox size)?
S1: This might sound silly, but can you please post pictures of the cabinets and boxes with some other object in the picture as well - to give us a visual perspective of how big/small it is? I see so many pictures of mini ITX cabinets and other HTPC cabinets, but almost all of them lack the size perspective. Looking at the pictures, I have no way to visually judge if it will fit in my media cabinet at all. I have to look at the dimensions every time and it is painful. For example, you could post a picture of the cabinet with a picture of an iPad alongside.

It's a 4.5" square and 1.5" tall. It's TINY.asliarun - Friday, January 3, 2014 - link
Thanks. Wow, that is tiny indeed. Slightly OT - I have a Minix Neo X5 which has somewhat similar dimensions and is also fanless. It is actually quite a credible audio (and average quality video) server. However, being on the Android platform and based on some Rokchip version, the lack of software support is frustrating. For example, I wanted to install LMS (Logitech Media Server) so that I can serve audio to my Squeezebox. However, there is no port of LMS to Android that I know of.Maybe, I should wait for the Silvermont version of NUC. It is supposed to release in the next couple of months. It can act as a fully fanless audio server. On second thoughts, having gaming expectations from this small a device is not a great idea.

I have the i3 Haswell NUC and use it solely as an XBMC server via OpenELEC. I leave it on all the time, with XBMC set to turn off its display after X minutes. I measured 6W idle on mine, which nicely matches Ganesh's findings.And sitting 8-10 feet away, I can't hear the fan at all. It's probably OFF when idling at 6W, and I still hear nothing during a movie (the quiet parts), as the NUC only pulls 13W when playing 1080P video.
I'm very happy.

There are already fanless mods of the current NUC, see for example http://tinyurl.com/p9vq9qmasliarun - Saturday, January 4, 2014 - link
I have been following fanlesstech for a while. They have written about some very interesting fanless cases. A surprising number of them are for the NUC.http://www.fanlesstech.com/
There's stuff from Habey, Streacom and the like. But also some exotic ones - very good eye candy.
This one is my favourite for example: http://htpc.jp/u3/index.html
Personally, I believe that a Bay Trail (especially Bay Trail D) / Silvermont based system is the best fit for a NUC form factor. We could build a very viable system for well under $500, with a system draw in the 10W-15W range that can give us a fully fanless system if we wanted to, and will still have the same horsepower as a Core2Duo system (Bay Trail D). I feel that Haswell is a wrong choice from a cost, heat, and noise perspective.
Here's an example: http://www.fanlesstech.com/2013/12/very-first-bay-...
The only open question is if these Bay Trail based HTPC systems will be capable of full blown HTPC duty. I would think so based on technical specs but real world is another thing entirely.
Maybe Anandtech could do a review?? :)
Wixman666 - Saturday, January 4, 2014 - link
I believe that the Haswell family is a better solution overall. The on die Intel 5000 video is GREAT. Even though the Bay Trail looks decent, it isn't as well-rounded.
