The Intel NUC6i5SYK Skylake UCFF PC Review
by Ganesh T S on March 11, 2016 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 35W TDP Core i3-6100T and the 28W TDP Core i5-5557U take the lead over the 15W Core i5-6260U.
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.
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 used to be restricted to high-end SKUs. That has changed now, and even the consumer-focused Core i5-6260U in the NUC6i5SYK has 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 NUC6i5SYK 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.
Bringing the GPU into the picture helps the NUC6i5SYK to emerge as the Stage 2 leader, but, in other stages, the raw CPU performance is held back by the lower TDP compared to some of the other PCs in the comparison list.
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 higher TDP CPUs perform better.

Nope, with Skylake Iris = 64MB of eDRAM. Iris Pro = 128MB of eDRAM. You're thinking of Broadwell.damianrobertjones - Friday, March 11, 2016 - link
I have the NUC615SYH model in front of me now with the following:-HyperX Impact 16 GB 2400 MHz
-Samsung 250GB 850 EVO M.2
-Samsung 850 500GB evo 2.5"
All okay, updated to the latest firmward, installed Win10 fine BUT, as is often the case, the auto-driver facility from Intel fails to install a few drivers. You have to manually download and install.
Issues? Yes... The ethernet connection states that there's no internet connection despite being able to get onto the net. No other driver to try at this point in time so I'm using a USB nic.
All in all not bad.

NUC5i7RYH- G.SKILL Ripjaws Series 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1866 (PC3 14900)
- Micron M510 M.2 128GB SATA III Internal Solid State Drive (SSD)
- Intel X25M G2 80GB :)
Except for updating BIOS, do NOT install any drivers from Intel. You will get random crashes and issues. Only use what Windows Update gives. Has been rock solid once i did a clean install. Intel's Update tool was broken several months back too. Very surprising that it could not install drivers on a NUC.
From reading the benchmarks, the new 6i5 is a just because release. Unless you really want card reader, but you need a HUB to attack K,M, printer,.. anyway...
I wish they'd gone another direction.
It would be nicer if there was a plain office/developer and non HTPC version. Strip out all the radios, SDXC, HDMI,...
Just
- TPM,
- Lan(dual for VMs would be great),
- DP(1.3 chaining is fine, soon enough real 39"-44" 4k monitors will allow one monitor setups),
- USB (2 USB 2.0: KB,M; 4 USB 3.0: Webcam, printer, UPS, spare; 2 USB 3.0 front: spare, dedicated cellphone charger)
- combined headphone/mic
- 2x M.2 slots. Boot and data. Able to do backups internally. Also for VMs. Running Hyper-V VMs on mine is super smooth.
- the 2.5" drive option is really out of place/ancient. Without it, the bottom plate could be vented instead of sides.
- The removal of radios would allow the cooling solution to be almost doubled in size. I personally have the plastic top removed to allow better cooling.
A non HTPC, office/developer oriented NUC.

2.5" isnt out of place until M.2 can actually catch up. M.2 is still limited to 512GB drives, and a 512GB m.2 cost more than a 1TB 2.5" SSD. And M.2 runs much hotter than 2.5"blahsaysblah - Friday, March 11, 2016 - link
Having the 5i7 in hand and using it for about 4 months now, the 2.5" is out of place in it. It interferes with cooling of everything on underside. It adds almost 3/4" height to the NUC where it was only 4.53" x 4.37" x 1.26" to begin with.Besides a vented bottom plate allowing the RAM, M.2(air flow is all they need) and other chips much better cooling its really the size issue.
I am running VMs on it with no issue. Taking a tiny NUC with you is much better than a laptop. For all the non-email jobs that require larger display and real keyboard. Again, saying a second non-HTPC line, the HTPC version can be used by folks just doing email.
The 5i7 was only offered in the larger format. I would not have gotten it given a choice. Hibernate, put in pocket. That 3/4" makes huge difference in usability.
Just a different point of view. For developers, engineers you need two internal drives and two M.2 drives are just fine.

As someone who uses a lot of VMs, I don't see how this is better than a laptop. Needing power, keyboard, mouse, and a monitor any time you need to use it doesn't sound convenient. I'm the opposite extreme, using a 17" laptop and 1.2TB of SSD space - but it's great for running software development VMs anywhere I need it, and I dock it to a 24" monitor in the office.bsly1314 - Monday, March 14, 2016 - link
+1. Furthermore, there seems no enough space to include power-loss protection in M.2 SSD. PLP is important for NUC which, unlike laptops, has no battery to act as backup. I live in third world where the electricity fails about once in a month...watzupken - Friday, March 11, 2016 - link
The real star of the Skylake is the GPU. CPU wise, its not much faster than Broadwell. And quite disappointed in areas where performance actually regress.
