Intel NUC5i5RYK Review: A Broadwell-U UCFF PC for Enthusiasts
by Ganesh T S on February 20, 2015 8:00 AM ESTPerformance Metrics - I
The Intel NUC5i5RYK was evaluated using our standard test suite for low power desktops / industrial PCs. We revamped our benchmark suite early last year after the publication of the Intel D54250WYK NUC review. We reran some of the new benchmarks on the older PCs also, but some of them couldn't be run on loaner samples. Therefore, the list of PCs in each graph might not be the same.
Futuremark PCMark 8
PCMark 8 provides various usage scenarios (home, creative and work) and offers ways to benchmark both baseline (CPU-only) as well as OpenCL accelerated (CPU + GPU) performance. We benchmarked select PCs for the OpenCL accelerated performance in all three usage scenarios. These scores are heavily influenced by the CPU in the system. The Core i5-5250U is obviously not as powerful as the Iris Pro-equipped Core i7-4770R in the BRIX Pro. However, note that the M.2 PCIe SSD and the faster DRAM (despite the lower latency) help the enthusiast configuration take a handy lead over the mainstream configuration in all the PCMark benchmarks.
Miscellaneous Futuremark Benchmarks
PCMark 7 seems to favor the Core i7 models much more compared to the PCMark 8 benches. However, even in this suite, the enthusiast configuration performs better (similar to what we saw in the previous sub-section). The faster memory also helps the GPU post better scores under the enthusiast configuration for the 3DMark benches. Surprisingly, HD 6000 doesn't perform better than the HD 5500 in the Broadwell BRIX s when the 3DMark 2013 scores are considered. However, 3DMark 11 clearly favors the HD 6000.
3D Rendering - CINEBENCH R15
We have moved on from R11.5 to R15 for 3D rendering evaluation. CINEBENCH R15 provides three benchmark modes - OpenGL, single threaded and multi-threaded. Evaluation of select PCs in all three modes provided us the following results.
As far as 3D rendering goes, the Broadwell-U NUC really doesn't provide any great benefits compared to the Haswell-U NUC. Faster memory helps with the multi-threaded and OpenGL-accelerated rendering a bit, but, other than that, there is really not much to talk about with this benchmark in terms of performance improvement.

I am a confirmed HTPC user, I have 2 in the house. One, more powerful, is used to rip Blu rays down to NAS, (plus play, Netflix/Amazon Prime, Web browsing) the other is used simply to play movies, browising, word processing and "Old" gaming - I am a big fan of Total War, old versions.Total silent operation is a must. I do not care how quiet the fan is, in soft parts of movie playback I can hear it.
The old i3 NUC, in a fanless case, makes for an excellent low power HPTC. A Broadwell U will be as good.
My problem is then I am not sure even that power is necessary for most HTPC use where simply streaming from NAS or similar external disk. For the next HTPC I am looking forward to reviews of Intels Bay Tree on a stick, so small it could be stuck behind my AV receiver

Having 'too much' power for an HTPC has two main advantages:1) Interface speed. This is both for actual rendering of the interface bells & whistles, and for populating large directories when browsing.
2) CODEC futureproofing. H.265 is on the horizon, and Hi10p H.264 has some very nice benefits in bitrate reduction (or better perceptual quality at the same bitrate), but low power hardware that relies on fixed-function decoder blocks will be left high and dry. Even if they DO have a FFB for a desired CODEC, it may not be sufficient to playback all files (e.g. the number of Level 4.0 h.264 decoders that can't handle full-bitrate Blu Ray streams).

I'm not sure you realize how little processing power is actually used for rendering. Even now on an old dual core pentium my htpc barely hits 10% utilization on one core while watching h.264 stuff at 1080p. My second htpc which has a ~$55 amd 5xxx series card does most of it via the video card, which also is nowhere even close to being taxed.This setup is WWWAAAYYYY past the needs of any kind of streaming/media/htpc. At these price ranges you can actually build a pretty decent desktop with a dedicated graphics card. Yes, it won't be this small, but you will actually have real graphics performance (i.e. a gtx 960 or r9 280, etc).

Wouldn't you consider an AMD-based system a better option for an HTPC? Asking as I am considering one.I recently bought an AMD-based laptop and I am extremely pleased with it as I find it much more effective for casual gaming and, frankly, the CPU performance gap with Intel is "irrelevant" for HTPC use (at least the one I have in mind).

YankeeDDL: Short answer is yes, AMD laptop in many cases is a much better HTPC (unless it has a fan!)But will it look good with the rest of your AV kit? My main HTPC is in a HDPLEX 3 case, which looks great (but pricey), my second HTPC is an i3 NUC in a Tranquil fanless case - again fits right into the AV style.
I guess it depends on what you want. Edzieba is clearly much more of a power user of an HTPC than I am. That does make him right and me wrong (or vice versa), just different. But I have yet to find any user of an HTPC who, with all else being equal, would want to have fans in the HTPC if it could run fanless

So you're saying an AMD laptop isn't a better HTPC then? Qualifying it with "unless it has a fan" kinda negates the possibility entirely.

Fans have one big problem, dust accumulation and can lead to clogging (in the cooling vents) which can cause overheating.owan - Friday, February 20, 2015 - link
Its not about being a power user... he's talking about why more cpu punch can be a good thing. If you don't have a fixed function decode block for a new codec and your CPU is too crappy to do it in software, then you need to buy a new CPU and mobo. If bay trail on a stick can't do h.265 you're screwed if you try to play h.265 content, but a broadwell NUC might be able to do it in software (assuming it can't decode in hardware... which it may)BlueBlazer - Saturday, February 21, 2015 - link
Agree, I ran into that problem years ago especially with Hi10p (10-bit H.264) which requires software decoding. Those low power slow CPUs (like AMD E-350 and Atom 330) just would not be able to decode it smoothly. Broadwell already has H.265 as well as 10-bit H.265 and VP9 support in its latest drivers: http://techreport.com/news/27677/new-intel-igp-dri...rmullns08 - Friday, February 20, 2015 - link
cjs150: Interesting that you bring up the HDPLEX 3 case. I currently use a D54250WYKH, but have one major complaint with it being the power supply. I don't use mine as much for HTPC, but do use it for an audio setup (Schiit Modi2 Uber/Magni2 Uber and JBL LRS305), and the power supply is so noisy. I've found that the PSU leaks noise on the negative side, into the chassis which is not properly isolated or grounded. Connecting the DAC results in noise shooting through the system even before the USB cable makes actual contact with the NUC. I've tried different surge protectors, relocating devices onto different outlets to no avail. The other day I actually ordered the HDPLEX linear power supply to hopefully resolve the issue once and for all.
