Intel's Haswell NUC: D54250WYK UCFF PC Review
by Ganesh T S on January 3, 2014 4:25 PM ESTMiscellaneous Factors and Concluding Remarks
Power Consumption:
We have already carried some graphs and tables with power consumption numbers for various scenarios in the preceding sections. The two graphs below compare idle and full load power consumption numbers across different low power desktops that we have evaluated before.
The Haswell NUC turns in stellar numbers for both scenarios. There is no doubt that this is a powerful, yet power-efficient, computing solution.
Thermal Performance:
The D54250WYK has an active cooling solution, but the size of the chassis is still a bit of a concern when it comes to cooling efficiency. To check the thermal performance of the kit, we let Prime 95 fully load up the CPU for 15 minutes, followed by the addition of Furmark to fully load the GPU also for the next 15 minutes. After this, the unit was left to idle while driving the display. Screenshots of the temperatures of various components (as reported by CPUID Hardware Monitor PRO) recorded at 15 minute intervals are presented in the gallery below.
At full CPU load, the temperatures of the cores reach 74 C, the fan spins at 3958 rpm (can go up to 4192 rpm) and the temperatures around the SSD (on the other side of the board) reach 43 C. With the GPU also fully loaded, the temperatures of the cores go down to around 67 C, the fan takes a little break at 3846 rpm. On the SSD side, the temperatures go a little further down to 41 C. After idling for 15 minutes after full loading, the cores are at 32 C, the fan is at 3206 rpm and the temperature on the SSD side goes down to 33 C. There is nothing to complain about with respect to the thermal solution except for the few notes about the fan noise that were made in the introduction.
Final Words:
From the HTPC perspective, it is troubling that HDMI audio still needs careful configuration in XBMC 12.3. For bitstreaming to work, XBMC has to be configured with WASAPI and not Direct Sound. The symptoms are the same as the Netflix HD audio issue. It is also a pity that interlaced VC-1 DXVA decoding doesn't work in XBMC. These are issues faced by the average consumer. We didn't touch upon the HDMI full range problem which HTPC enthusiasts treat as primary issue. All in all, it looks like Intel's graphics drivers still need to resolve lots of issues. While we have seen stellar progress over the last couple of years, it only leaves consumers asking for more to completely move away from discrete GPUs for HTPCs.
Moving away from the HTPC area, the NUC's low power consumption as well as small footprint enhance its appeal for use as thin clients or even full blown PCs for average office / home desktop use. The traditional desktop is being re-imagined in multiple ways with the advent of the touchscreen AiOs and form factors such as the NUC and the BRIX. The comparatively low cost and flexibility provided by the latter has ensured that the NUC form factor is here to stay as yet another excellent computing platform option for consumers.

I'm confused by the comments about the Brix Pro. I still haven't seen a price or even release date for it. Do you guys have inside knowledge of it? I kinda thought it might have been cancelled...elian123 - Saturday, January 4, 2014 - link
I haven't found much information either, although this did look good to me: https://twitter.com/IntelGaming/status/41454908150... Ganesh's remark that he has a review unit (http://www.anandtech.com/comments/7566/intels-hasw... is even better of course.cen - Saturday, January 4, 2014 - link
I never understood why Anandtech never mentiones anything about Linux in their hardware reviews. This seems like a perfect htpc device to put Linux on and I am sure that some readers would be happy to know what are the hoops to go through on the Linux side, the state of Netflix, any driver issues etc. Why pay the Windows tax if you can get the same or pehaps even better experience for free?fackamato - Saturday, January 4, 2014 - link
Just check out the HD5000 GPU support under Linux, that should give you a good idea about the HTPC capabilities.patterson32 - Saturday, January 4, 2014 - link
There are other components where it would be nice if they were tested on Linux especially as part of a particular system like the BRIX and NUC. Scouring for info for each component is less desirable than having the entire system tested and reviewed in a single article.patterson32 - Saturday, January 4, 2014 - link
I always hope AT will write more on Linux topics but they never do. The focus is almost solely on Windows. It'd be nice if they did hardware reviews with Linux and give the usual details of what works and what doesn't and other very detailed information.The only okay site I know of that does Linux hardware stuff is Phoronix but that site uses tests that aren't that meaningful especially for non-GPU hardware and desktop use. For other hardware, they just gloss over many details. Their "analysis" are often blurbs like the power consumption is less than system x. Useless, I can see that on the graph and the system x is some much higher performing non-comparable device.

Phoronix hardware "reviews" aren't very useful for potential buyers who want to use Linux apart from Michael's GPU driver tests. It'd nice if AnandTech started writing Linux articles.chizow - Saturday, January 4, 2014 - link
Main limitation I think for HTPC use for people like me is lack of ability to play CableCARD DRM content. I've looked into the alternatives, and there still isn't anything on the Linux/Android/iOS market yet that can replace Windows Media Center for Premium CableCARD content (HBO, MAX, SHO etc.) DLNA is enabling some workarounds (PS3, native SmartTV Apps), but the end-product still isn't as good or as fast as WMC's interface.Lundmark - Saturday, January 4, 2014 - link
HD audio. I don't think you can get HD audio on Linux.ganeshts - Sunday, January 5, 2014 - link
Just testing out OpenELEC right now and HD audio passthrough support is great in the latest dev build. That is an embedded Linux system :)
