Performance 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. The cTDP-Up of the Skylake BRIX enables it to to get slightly higher numbers in the second pass when compared to the Kaby Lake Cubi2-005BUS. Actual x264 encoding performance with the Kaby Lake processors and using the latest x264 releases (with AVX512 AVX2 support) is bound to be even better compared to the numbers below.

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. Almost all modern CPUs support AES-NI for acceleration of the cryptographic processes. The Core i7-7500U in the Cubi2-005BUS does have AES-NI support. TrueCrypt, a popular open-source disk encryption program can take advantage of the AES-NI capabilities. In the graph below, we can get an idea of how fast a TrueCrypt volume would behave in the MSI Cubi2-005BUS and how it would compare with other select PCs. This is a purely CPU feature / clock speed / TDP-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.

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 cTDP-Up of the Skylake BRIX makes it come out on top.

    I just spent 20 mins looking at the power & thermal charts. It's fascinating to see how the CPU & GPU clock respond to the shared 15W power and thermal budget of the integrated package. Time 1800-3600 shows how the GPU steals performance from the CPU, resulting in the CPU clock dropping to 1.2 GHz, far below the Core i7-7500U spec of 2.7 GHz. I've always thought it misleading to claim this a 15W 2.7GHz CPU, when this is only the case if GPU utilization is negligible.

    That is indeed interesting, but the whole i7 label on these chips is misleading in my opinion.
  • BrokenCrayons - Tuesday, January 3, 2017 - link

    I know right. There've been i7 dual core processors since 2010 or so and despite all those years, it's still dreadfully complicated and confusing. Intel is so hush-hush about specifications too. They don't publish anything about the CPU specs. It's like they're all mysterious black boxes.

    If it's same as cubi 1, the heat sink fan mounts are soldered onto the pcb.

    They're weak and fall off. The system will barely last to warranty and is difficult to repair.

    "We didn't evaluate 4K Netflix streaming on this PC because there is no HDCP 2.2 support."

    Intel really dropped the ball in regards to their Y and U chips not being able to decode HDCP 2.2 streams. Do we know if the 200-series chipset for LGA 1151 Kaby Lake processors will include native HDCP 2.2 support, or will it be the same story there?

    At the end of the review: "Over the next few months, we will be reviewing a few more Kaby Lake-U PCs that bring in features like HDMI 2.0b and full Netflix 4K support with HDCP 2.2"
  • Pazz - Saturday, December 31, 2016 - link

    In respect of the HDCP 2.2, Ganesh is referring to the Beebox-S and BRIX Kaby Lake models which both feature a LSPCon.

    I'd still rather have the skulltrail unit
  • 1_rick - Friday, December 30, 2016 - link

    You mean the skull canyon NUC? It's pretty awesome--I have one. With 16GB of RAM you can run two simultaneous VMs running small SQL Server database as well as light gaming in the host OS. You wouldn't want it for high-end gaming without an eGPU, but for everything else, it's pretty sweet.

    That's the one! It is similarly priced but even a year later holds it's own with the iris GPU
