Zotac ZBOX CI540 nano Review: A Fanless Haswell-Y mini-PC

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 i5-4210Y performs really well except when compared to units sporting CPUs with much higher TDPs / clock rates.
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. 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 i5-4210Y in the ZBOX CI540 nano 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 Zotac ZBOX CI540 nano 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, with the unit making an appearance in the middle of the graphs. As expected, the performance is better than that of the BXBT-1900 and the ECA LIVA.

To be honest, I'm not too crazy about this "super small" mentality. It seems like people are going super small as an end into itself more than anything else.The problem is that smaller means that more heat has to be put through a small space, as this example here shows. A slightly larger design here I think would have been an advantage.

Yes it seems you can go from a m-atx box to something minute. Doesn't have to be 'as small as you can make it'. Something the size of say a PS2 or a little smaller would be fine.Calista - Saturday, November 1, 2014 - link
Fully agree, even something in the 20x20x20 cm size doesn't occupy much more size then say a NUC once we include space for cables for power, monitor, keyboard and mouse.Alexvrb - Sunday, November 2, 2014 - link
Agreed. I can't imagine going smaller than a baby ITX box, if for no other reason than it's easier to upgrade or modify. :Djosue16 - Friday, October 31, 2014 - link
Will you guys add LAN latency tests? That is if it can be reliably measured. Also, gigabit Ethernet tests would be nice too.knightspawn1138 - Friday, October 31, 2014 - link
I like the thermal pictures. It looks like a space age furnace or reactor. Or like it's a box of lava. Not sure if I want to hang this on the VESA mount on the back of a $1500 TV set.bobbozzo - Friday, October 31, 2014 - link
Can SSDs tolerate 75C?Shadowmaster625 - Friday, October 31, 2014 - link
$500 for a notebook with no screen and no battery/UPS. What a great deal! Sign me up for 3. NOTzodiacfml - Saturday, November 1, 2014 - link
i agree. the notebook i'm using now is only 250 USD with probably the same performance of this low voltage cpu.kmmatney - Friday, October 31, 2014 - link
I've never had an "HTPC" (I have a windows home server and a WD live player) so I'm not an expert on this, but couldn't a laptop perform the same function? It's cheaper and a lot more capable. $350 gets you a core i5 laptop with HD4400 graphics not to mention a keyboard, screen, and OS. Maybe it takes a little more space, but having the screen would make it easier to setup.
