Intel NUC5i5RYK Review: A Broadwell-U UCFF PC for Enthusiasts
by Ganesh T S on February 20, 2015 8:00 AM ESTPerformance Metrics - II
In this section, we mainly look at benchmark modes in programs used on a day-to-day basis, i.e, application performance and not synthetic workloads.
x264 Benchmark
First off, we have some video encoding benchmarks courtesy of x264 HD Benchmark v5.0. This is simply a test of CPU performance. As expected, the configurations based on the Core i5-5250U are not as powerful as the Core i7-based ones. The effect of faster memory is almost non-existent. The slightly higher burst frequency of the Core i5-5250U (2.7 GHz) compared to the Core i5-4250U (2.6 GHz) help the NUC5i5RYK take a slight lead over the corresponding Haswell NUC.
7-Zip
7-Zip is a very effective and efficient compression program, often beating out OpenCL accelerated commercial programs in benchmarks even while using just the CPU power. 7-Zip has a benchmarking program that provides tons of details regarding the underlying CPU's efficiency. In this subsection, we are interested in the compression and decompression MIPS ratings when utilizing all the available threads.
Results in the compression benchmark are similar to what we observed for 3D rendering - Broadwell-U doesn't provide too much benefit over Haswell-U except when burst frequencies play a major role. This is understandable - 14nm helps sustain higher clock rates for the same power consumption.
TrueCrypt
As businesses (and even home consumers) become more security conscious, the importance of encryption can't be overstated. CPUs supporting the AES-NI instruction for accelerating the encryption and decryption processes have, till now, been the higher end SKUs. However, with Bay Trail, even the lowly Atom series has gained support for AES-NI. The Core i5-4200H in the BXi5G-760 does have AES-NI support. TrueCrypt, a popular open-source disk encryption program can take advantage of the AES-NI capabilities. The TrueCrypt internal benchmark provides some interesting cryptography-related numbers to ponder. In the graph below, we can get an idea of how fast a TrueCrypt volume would behave in the Intel NUC5i5RYK and how it would compare with other select PCs. This is a purely CPU feature / clock speed based test.
Agisoft Photoscan
Agisoft PhotoScan is a commercial program that converts 2D images into 3D point maps, meshes and textures. The program designers sent us a command line version in order to evaluate the efficiency of various systems that go under our review scanner. The command line version has two benchmark modes, one using the CPU and the other using both the CPU and GPU (via OpenCL). The benchmark takes around 50 photographs and does four stages of computation:
- Stage 1: Align Photographs
- Stage 2: Build Point Cloud (capable of OpenCL acceleration)
- Stage 3: Build Mesh
- Stage 4: Build Textures
We record the time taken for each stage. Since various elements of the software are single threaded, others multithreaded, and some use GPUs, it is interesting to record the effects of CPU generations, speeds, number of cores, DRAM parameters and the GPU using this software.
The results show that the faster DRAM helps despite increased latency. GPU acceleration proves beneficial in cutting down the time taken for the second stage considerably.
Dolphin Emulator
Wrapping up our application benchmark numbers is the Dolphin Emulator benchmark mode results. This is again a test of the CPU capabilities, and the Core i7-based models obviously trump the Core i5-based ones.

Damn, wrong post, please ignore.medi03 - Sunday, February 22, 2015 - link
Lack of AMD APUs in comparison charts is somewhat suspicious, to say the least.mits2k - Monday, February 23, 2015 - link
I am glad that Anandtech is evaluating 4K playback on these devices. Regular 1080p HTPCs seem to have reached a plateau in the past few years.I was confused by the evaluation of 4K scaled to 1080p. Are the new LAV filters that fix the scaling issues incorporated into the latest MPC-HC? Will LAV be taking advantage of the partially in-hardware 4K decoding via DXVA on Intel QuickSync soon? Does the HDMI output of this device support HDMI 2.0, enabling 4K/60p/4:4:4 color bit-depth? If not, does the DisplayPort support this bitrate? Will this device support HDCP 2.2 for protected 4K bluray output?
I bought an ASUS chromebox ($179 version) and have been successfully using it with my 4K monitor (Monoprice model) and 4K TV (Samsung). It renders the desktop in 4K30Hz, not at 60Hz. It is too slow/there is not appropriate software in linux to handle 4K videos without occasionally dropping frames, so I was going to upgrade to the NUC to handle this.

"The first Sandy Bridge NUC was important for two main reasons - the obvious one being the kickstarting of the UCFF craze."What, no nod to the Mac Mini, circa 2005? (Or even the G4 Cube if you want to geek out with me...)

He didn't say NUC was the first but that it kick started the current popularity of the form factor.Haravikk - Wednesday, February 25, 2015 - link
I'm doing quite well on a small form factor system at the moment, using an i7-4790T (45W 2.7ghz quad-core, hyper-threading, 3.9ghz turbo and HD4600 graphics) in an Akasa Euler case. Only downside has been that I had to trade in the mSATA hard drive I was using for a regular 2.5" SSD, as the mSATA just got too hot in such a confined, passively cooled space.jasperjones - Wednesday, February 25, 2015 - link
I am shocked what you guys use as a HTPC. And what good are these SSDs in a HTPC???I use a rooted Amazon Fire TV as my HTPC (purchased for € 49 at the introductory rate for Prime customers). Thus far, it has handled everything I've thrown at it. By the time I need H.265 and 4K, I imagine another ARM box priced below a hundred bucks will be around.
To me, this NUC is a desktop replacement (for non-gamers) or a small-server replacement.

I have no idea why somebody is even bothering to try AMD - they are horrible.I am in market for small and lightweight PCs, and have used AMD once - it ate twice the current of NUC yet twice slower. So 1/4 performance per power. Oh and it wasn't that cheaper too.

Well I would just compare this to at least a desktop Pentium, i3,i5, i7 to see what the difference is. Is this weak slow running processor as good as say an i3 4330 that runs at 3.5 Ghz, with 4 Megs of Cache, and HD 4600 IGP?Ceois - Wednesday, March 4, 2015 - link
On the first picture from the BIOS gallery it says CPU Core Temp 51C. Isn't that a little too high for it being idle?
