Zotac ZBOX MAGNUS EN970 Review - A Gaming mini-PC Done Right
by Ganesh T S on September 28, 2015 8:00 AM ESTPerformance 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 U-series based system comes in at the bottom of the pile compared to the CPUs with much higher TDPs.
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 i5-5200U in the ZBOX MAGNUS EN970 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 MAGNUS EN970 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.

I would be very curious to hear more about the GPU rebranding situation... why would a 1280-shader GM204 on an MXM card be a 970m in a laptop but a 960 non-M in a SFF? Why would Nvidia/Zotac go to the trouble of editing the VGA BIOS and drivers to make this GM204 show up as a 960 when there are already loads of MXM 970m's that are functionally identical to this aside from re-badging? The OEM GPU re-branding situation is ridiculous; Zotac/Nvidia have created a doubly confusing situation where this card could be easily confused for either a significantly-slower GM107-based GTX 960m (that's itself a rebadged 860m) or a slightly-slower GM206 GTX 960 that has the potentially-important HEVC decode that's actually not present in this "960".KateH - Monday, September 28, 2015 - link
And while I'm on a rant, re-badging between generations is ridiculous too- but I know by now that's a losing battle that's only getting worse. FFS.mapesdhs - Monday, September 28, 2015 - link
A lot of that going on by all sides, but it's hard to discuss without enraging rival armies of haters and fanboys. We'd be a lot better off if nobody did it. What really bugs me is the massive performance overlap of newer lesser models vs. older models. The naming system allows one to infer that a newer card will have a particular level of basic performance, but the reality is often very different. I benchmarked a 650 Ti recently, was amazed to find it often failed to beat an old GTX 460.lmcd - Tuesday, September 29, 2015 - link
I mean the 650 Ti should be like 2/3 the power consumption at most, no?KateH - Tuesday, September 29, 2015 - link
Yeah, something like that. ~100-120W for a 650Ti vs ~150-170W for a 460. The 660 is in the same power envelope as the 460 and should outperform it by a fair marginrtho782 - Tuesday, September 29, 2015 - link
You're perfectly right. Having a separate mobile product stack made sense when mobile gpus were way behind desktop ones, now they use the same silicon, less so.I think we should have the same product names and tiers for both, perhaps use the "m" suffix in cases where the clockspeed is much lower in the laptop variant.
KateH - Tuesday, September 29, 2015 - link
I kinda wonder if it's not time to do away with the "M" suffix for GPUs altogether and move towards segmentation based on power, like what Intel has done with their K/S/H/Y/U suffixes. Low-power MXM/onboard GPUs are by no means strictly in the realm of notebooks anymore- AIO and SFF computers are using them more and more. And looking at AMD/NV's product stacks, "desktop" GPUs cover ~15W-250W (with all but the top-end being under ~150W) and "mobile" GPUs cover ~15W-125W- that's a whole lot of overlap.ruthan - Tuesday, September 29, 2015 - link
Better than Macmin, but otherwise is better build own, even if MXM is not possible to use by us second category people..adithyay328 - Thursday, October 1, 2015 - link
Those specs actually almost give my mid tower desktop a run for it's money-almost.aj654987 - Friday, October 2, 2015 - link
Well, for the alienware alpha with the 860m and the T series processors (Haswell 35W), the CPU's are almost all GPU limited, even the i3's. So there is room for a higher powered GPU.With going broadwell, the lowest desktop CPU is 65 watts so far, which is probably too high for that small case, so their only choice is a 15 watt mobile chip.
