Zotac ZBOX MAGNUS EK71080 Compact Gaming PC Reviewby Ganesh T S on March 28, 2018 8:00 AM EST
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.
First off, we have some video encoding benchmarks courtesy of x264 HD Benchmark v5.0. This is simply a test of CPU performance, and there is no hit from the Meltdown and Spectre patches. As expected, within the same number of threads, the higher TDP desktop CPU-based systems perform better. Recent releases of the x264 benchmark can show even more impressive gains, as they make use of the latest and greatest features of the modern Intel processors.
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 become more widespread over the last few years. 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 Zotac ZBOX MAGNUS EK71080* and how it would compare with other select PCs. This is a purely CPU feature / clock speed based test.
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). We have been using an old version of the program with 50 photogaphs in our reviews till now. The updated benchmark (v1.3) now takes around 84 photographs and does four stages of computation:
- Stage 1: Align Photographs (capable of OpenCL acceleration)
- 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.
Wrapping up our application benchmark numbers is the new Dolphin Emulator (v5) benchmark mode results. This is again a test of the CPU capabilities, and the 65W TDP CPU-equipped EN1080K performs better than the EK71080.
