VisionX 420D Review: ASRock's mini-PC Lineup Continues to Impress
by Ganesh T S on September 1, 2014 9:00 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.
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 i5-4200M in the VisionX 420D does support AES-NI. 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 VisionX 420D 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.

You could write a small paragraph commenting on the relative performance. For example, in Office suite benchmarks make a comment whether it's likely the CPU or storage that's holding it back. Right now it's just a bunch of charts with little commentary.creed3020 - Wednesday, September 3, 2014 - link
I would have to agree. Charts without commentary provides the reader little to no analysis. I'm not saying that we're all stupid on this end to spot obvious charts but take this an opportunity to really let the review shine and stand above the rest of the crowd. Running benchmarks and posting charts is something any tech website any do...yannigr2 - Tuesday, September 2, 2014 - link
In a way you are already doing what I am suggesting in the Agisoft Photoscan graphs where you have two bars for each machine and you specifically mark those that also use the gpu. Giving the gpu info in the gaming benchmarks(for example Habey ... (HD 4000)) and the cpu in metrics (for example Habey ... (i7-3720QM) ) will make the review graphs easier to read. Also a big difference between two mini PCs with the same GPU or CPU could make a few readers more curious about the results and force them to find out about that influence of the memory or the storage subsystem that you have noticed but most of as ignore.Now the easiest way to read this review is to keep two pages open, one in the first page and the second with the print view of the article. But going all the time from one page to the other is a little more work for the reader than usually (we are really lazy, believe me).
Anyway, too much and good work in this article. Thanks for answering my post.

Awesome article. I love reviews of small footprint/HTPC systems.I'm sure with all of the press surrounding the upcoming Alienware Alpha that you are more than likely to have a review for that in the coming months, but in the meantime if you guys get your hands on a Zotac EN760(which is similar internally to the Alpha) for review that would be awesome to see stacked up against this thing.

Thanks for a great review - I especially like the objective, candid and insightful "concluding remarks" in this and other Anandtech reviews.Suggestion for a future HTPC review - JRiver recently started selling their own HTPC called the "Id", based on an OEM NUC design. I think it would be good to review not only for its hardware and software merits, but also because JRiver seems to be really thinking out high performance, cost-effective ways to manage and distribute home audio and video that other companies either ignore or charge thousands for. With the disappearance of the Squeezebox Touch and disappointing audio performance of RPi, JRiver seems to have the best end-to-end vision and implementation of really good, affordable home media solutions. Just my humble opinion, but interested in what Anandtech thinks about the best solutions that consider HTPCs, NASs, networks and renderers for home entertainment.

I've mentioned this before but I looked into building a mac mini "clone" awhile back using this same case. The problem I ran into was the power supply: I didn't want a brick.Why, why, why, would an oem build this system with a power brick? I can do that. What I can't do is find a power supply that will fit in the case.

Get a case with a PSU, like the Chieftec FI-01B-U3 or LC Power 1370BII. A bit bigger than these HTPCs, but so is the Mac.tuxRoller - Monday, September 1, 2014 - link
The macmini used this exact case, iirc.Thanks for the suggestions, though! I'm always on the lookout for new, small cases.

Is there any way for the consumer to get hold of one of these motherboards or kits that support those magical S0ix sleep states without opting for these insufferably noisy and pointless mini-box solutions?I don't want to pimp my ride with one of these or the backside of a monitor, I just want a PC that consumes little idle power, that lets me attach a large silent heat sink.
Perhaps as mini-ITX with a DC in. ASRock makes DC-powered boards for BayTrail, but why not Haswell?

I've had my Vision 420D since May and it has been a dream portable gaming/XBMC machine. I was able to install two 2TB hard drives and a 250GB mSATA drive. I was even able to upgrade the CPU chip to an i7-4702MQ without much trouble. The heat temperatures of the CPU are rather outstanding when compared to the Brix Pro which can go as high as 100C when gaming versus 82C for the VisionX. My Steam games and high end emulators run extremely well at 1080P without overheating or throttling. It is also not noisy at all. In addition, XBMC runs like a dream on this machine. I loved the fact too that I was able to take this with us during our family summer vacation trips. We had portable gaming and XBMC on our trips. ASRock definitely hit a home run with this model and we just love it!
