Logic Supply ML100G-50 Fanless Skylake vPro Industrial NUC Review

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 Core i5-6300U helps the ML100G-50 come out on top. It is followed by the Broadwell-based ML100G-30 and the Skylake i3-based Zotac ZBOX CI523 nano.
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. The pattern of results is similar to that seen in the x264 benchmark.
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 have hardware acceleration for the encryption and decryption processes. The Core i5-6300U in the Logic Supply ML100G-50 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 Logic Supply ML100G-50 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 ML100G-50 comfortably comes out on top in all the stages, as expected.
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 i5-6300U's specifications ensure that the ML100G-50 comes out on top again.

Yet the fins are oriented in the worst possible manner convection wise. Vertical fins on the sides would be far more efficient than the horizontal fins on top. That assumes it is oriented as pictured. If the box itself is mounted so that the fins are perpendicular to the ground then it will be fine.DarekLogic - Thursday, March 2, 2017 - link
Hi ddriver, Darek here from Logic Supply, thanks for your comment. The fin designs for our chassis are partly driven by manufacturing methods. We utilize one-piece extrusions for their superior material properties and cost efficiencies (over say, casting or straight CNC). That does limit us somewhat in the orientations of our fin structures. Ultimately the layouts we go with are designed/tested for a balance of forced and natural convection (as well as installation flexibility for our customers and, to a lesser extent, aesthetics) in multiple orientations - like you said, with the chassis mounted on a vertical surface the fins are optimal, and that's very often how our customers deploy our systems.ddriver - Thursday, March 2, 2017 - link
Sure, you are extruding stuff like heat sink fins, it would be crazy to machine that. But you can just extrude the box with the sides flat, then bolt on auxiliary vertical fins, in that case you are set for both unit orientation cases.Or you could punch series of square C holes to the sides and bed the inner part outward, maybe not all the way to 90 degree, like 45 or so would do it, creating less of fins and more of a cool looking "ribs".
Both solution in case you want to increase the cooling capacity, visual aesthetics aside, the way it is looks tidier. But you can't always have it both pretty and efficient at the same time.
There is a third option - hide the fins. In that case they will be more like pipes, essentially cover up the fins but leave holes on the bottom for air to come it. Also, air expands as it gets hotter, so making the holes wider towards the top will be beneficial to increasing the air flow rate.

I can't speak for this particular device, but I've bought similar-looking industrial PCs for field use in the past (made by Advantech), and they're typically mounted vertically in a cabinet or on a wall using a DIN-rail mount.SkipPerk - Wednesday, April 19, 2017 - link
We do the same thing. It keeps them safely out of the way.dave_the_nerd - Monday, February 27, 2017 - link
I think there may be a typo on the last page:"Logic Supply's ML100G-50 is a solid step up from the Broadwell-based ML100G-50"
Don't you mean the Broadwell-based ML100G-30?

Seems like a pretty capable and up-to-date industrial PC for the money. I'm used to working with ones that are many, many more generations behind the curve.As an electrical engineer who builds panels for machinery I loathe the idea of an AC-DC power adapter and a barrel plug, but it looks like you can order it with DC terminals on-board so that's fine. Not bad then!

The only thing I'd use one of these for would be a nice compact and power sipping pfSense router box.IN order for me to do that, I'd need dual Intel NIC's though.
Why do all of these NUC's insist on either having only one NIC or using inferior Realtek NIC's you'd never want to use in a server-type setting?

Hi mattlach, Darek here from Logic Supply. Because we don't currently do any board-level development, we're limited to the motherboards available on the market. We are in talks with a number of motherboard manufacturers about creating additional options because we also see value in offering dual NIC connectivity in this form factor with Intel Core processing.That said, our ML100G-10 system does provide 2x Intel-based LAN ports (https://www.logicsupply.com/ml100g-10) and we have a number of clients using that system for various networking applications.
Thank you for your comment.
