ECS LIVA X Review: A Fanless Bay Trail-M mini-PCby Ganesh T S on January 16, 2015 11:30 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 LIVA X is better than the LIVA, but loses out to the quad-core solution in the ZBOX CI320 nano.
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 Avoton and Rangeley, even the lowly Atom series has gained support for AES-NI. Unfortunately, the Celeron N2808 doesn't support AES-NI. TrueCrypt, a popular open-source disk encryption program can take advantage of the AES-NI capabilities. Its 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 X 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.
Wrapping up our application benchmark numbers is the Dolphin Emulator benchmark mode results. This is again a test of the CPU capabilities, and the LIVA X is better than the LIVA as expected. Surprisingly, the performance of the ZBOX CI320 nano took a hit in this benchmark, and the LIVA X surprisingly pulled ahead.

zepi - Friday, January 16, 2015 - linkHEVC / H.265 decoding capabilities would also be of interest for all HTPC tests.
Otherwise these are solid articles about htpc's.
YoloPascual - Friday, January 16, 2015 - linkWell, this might be the best looking NUC out there.
yannigr2 - Friday, January 16, 2015 - linkCould you please try to do a review for this one?
It looks much more interesting than the LIVA.
kaidenshi - Friday, January 16, 2015 - linkOoo, the multi-LAN version of that would work great as a custom router/firewall!
speculatrix - Wednesday, January 28, 2015 - linkPhoronix.com looked at the fitlet
takeshi7 - Friday, January 16, 2015 - linkI think the Zotac PI320 is a much better value. It's $50 cheaper, has 2 more cores and comes with an OS. The only real advantage I see in this is more RAM.
Oxford Guy - Monday, January 19, 2015 - linkWhat does anyone need those extra cores for?
eanazag - Friday, January 16, 2015 - linkI'd like to see VGA ports die already, but I understand they may have customers looking for that. I'd rather see the HDMI and a DP port for the video out.
kaidenshi - Friday, January 16, 2015 - linkAt first I had the same reaction as you, then I remembered that a lot of digital signage (a target market for these devices) still uses VGA. Hell, I still have a 15" VGA only LCD around here somewhere, and I would be able to slap this on the back and make a great "kitchen PC" for when I'm cooking and need to research ingredients or methods.
But yes, a DisplayPort or mini DisplayPort connector would make more sense, given how cheap DP to VGA adapters are.
jabber - Saturday, January 17, 2015 - linkI think what you are looking for there is a laptop.
