ECS LIVA One Skylake mini-PC Reviewby Ganesh T S on February 1, 2016 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. As expected, the Core i3-6100T emerges the winner by a big margin for the same reasons that it came out in front in the CPU-based Cinebench R15 3D rendering tests.
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. Again, the ECS LIVA One emerges as the winner due to the presence of the Core i3-6100T
As businesses (and even home consumers) become more security conscious, the importance of encryption can't be overstated. The Core i3-6100T supports AES-NI instructions for accelerating the encryption and decryption processes. TrueCrypt, a popular open-source disk encryption program (that has since seen development discontinued) 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 ECS LIVA One 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). 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. These results are similar to the Futuremark benchmarks, as the memory configuration can result in a huge impact on the scores. With a single-channel configuration, the ECS LIVA One is at a disadvantage even when the other factors (newer microarchitecture, higher TDP etc.) are considered.
Wrapping up our application benchmark numbers is the Dolphin Emulator benchmark mode results. This is again a test of the CPU capabilities, and the ECS LIVA One emerges as the winner by a huge margin.
