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. As expected, the Core i7-5557U performs much better than any other U-series CPU that we have tested so far. Thanks to its high TDP, it can sustain higher clock rates. Obviously, it is no match for the 65W TDP Core i7-4770R in the BRIX Pro.

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.

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 i7-5557U in the NUC5i7RYH 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 NUC5i7RYH 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.

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 trend observed in the previous benchmarks in this section get repeated here. The Core i7-5557U is simply the highest-performing U-series CPU that we have evaluated so far.

    Yikes! This Intel's NUCs are expensive. $300 I'd bite. $900 no way.

    On the last page you lambash this unit for having mini-HDMI, yet in the photo's it appears to have full-size HDMI. I see mini displayport there though, did you mean to say mini displayport instead of mini-hdmi?

    In the Power Consumption and Thermal Performance section, did I read the graph correctly in that the CPU will throttle down to around 1.5 GHz when the GPU is loaded ? That's like half the speed. Where I'm this i7 NUC cost nearly $200 more than the i5 NUC, what's the point if it will only run at the i5 speed when it really matter.

    I've been undecided between buying this i7 NUC and the Brix Pro 4770R. I prefer the Brix Pro performance but the overheating and high failure rate of the Brix Pro in the long run has kept me away from buying it. But this NUC can reach 105 degrees anyway. Anyone here own Brix Pro 4770R willing to comment ?

    I love my NUC! I'm using very successfully as a Plex Media Server :)

    Here if you are interested:

    What is the height in mm with the lid & rubber feet removed?
    I am trying to figure out if it will fit within 1 rack unit? = 1.75 inches (44.45 mm)
