Shuttle XPC slim DH370 mini-PC Review: A Compact Digital Signage Powerhouse
by Ganesh T S on May 6, 2019 8:00 AM ESTMiscellaneous Performance Metrics - II
Continuing our presentation of benchmarks of real-world workloads, this section discusses Agisoft's Photoscan and the Dolphin Emulator, followed by an evaluation of the storage aspect of the XPC slim DH370 configuration.
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). We present the results from our evaluation using the CPU mode only. The benchmark (v1.3) takes 84 photographs and does four stages of computation:
- Stage 1: Align Photographs (capable of OpenCL acceleration)
- 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, and others multithreaded, it is interesting to record the effects of CPU generations, speeds, number of cores, and DRAM parameters using this software.
The power of the Core i7-8700 again comes to the fore, as the XPC slim DH370 sweeps the workload across all stages comfortably despite the slower RAM.
Dolphin Emulator
Wrapping up our application benchmark numbers is the new Dolphin Emulator (v5) benchmark mode results. This is again a test of the CPU capabilities.
The XPC slim DH370 completes the benchmark in the least amount of time, followed closely by the Bean Canyon NUC. Overall, in CPU-intensive workloads, the compact form-factor of the XPC slim DH370 doesn't seem to affect the capabilities of the Core i7-8700.
Storage Performance
Storage performance is a major aspect which influences our experience with any computing system. On the storage side, one evaluation option would be the repetition of our strenuous SSD review tests on the drive(s) in the PC. Fortunately, to avoid that overkill, PCMark 8 has a storage bench where certain common workloads such as loading games and document processing are replayed on the target drive. Results are presented in two forms, one being a benchmark number and the other, a bandwidth figure. We ran the PCMark 8 storage bench on selected PCs and the results are presented below.
The XPC slim DH370 is handicapped by the use of a PCIe 3.0 x2 NVMe SSD (compared to the x4 SSDs in most of the other systems). Yet, the numbers are well behind the DeskMini A300, which also used a PCIe 3.0 x2 NVMe SSD (WD Blue NVMe). If the storage sub-system is important for the use-case, the end user can do much better than the Kingston A1000 that our review system was configured with. In fact, using the WD Blue NVMe SSD could provide better performance numbers at a lower cost. PCIe 3.0 x4 NVMe SSDs are also supported, if needed.

Don't get me wrong, I would like that too. SilentPCReview.com needs to be revived perhaps. They, and their community, were the best. People lost interest I guess once storage drives, power supplies, retail computers, even GPUs improved noise by a lot. Plus other reviewers started paying attention to noise partly through their work. But with mini PCs and HTPCs maybe there is renewed thirst for noise analysis.The issue may be - how does Ganesh prevent outside factors and just the changing ambient noise level from influencing noise measurements? He would need some type of anechoic chamber and probably some audio equipment. Read this to see what goes into it, for removing outside influence and actually having a low enough ambient noise level for meaningful measurements - http://www.silentpcreview.com/anechoic_chamber_SPC...
Then there are logistics issues. Will Anandtech pay for or provide what may be needed? Does he do review work at his house/apartment? Is there an Anandtech central office? Do other Anandtech reviewers mostly live in the same area? Can someone rent an anechoic chamber? Keep in mind SPCR was mostly one guy on a mission, while Anandtech and Ganesh have plenty of other concerns.
Is there a spot in the middle where noise measurements are "good enough"? Any ideas? I do see noise measurements at other review sites sometimes, but I don't know if they are good enough for comparing among different product reviews that took place at different times and possibly at different places.

This query comes 3 years later, so I know that the odds on a response are not good, but WHICH existing Shuttle model is going to have more than adequate HTPC chops and features, as well as the desired quietness, heat dissipation, and reliability characteristics ? (Regardless of price, even.) I say existing model because I like Shuttle, and I don't care to build something from scratch out of disparate parts that may be available. The SH67H3 cube that still serves as my desktop computer would certainly fill the bill, and is plenty quiet even a few inches away on my desk, but of course it is several times the size and would require space I don't have in either of my video stacks.Another design factor that struck me as being perhaps dubious in these more compact, digital kiosk or signage oriented models has been the move to outboard power bricks, rather than an integrated PSU. But perhaps that is unavoidable, given the compact size.

How about 3D BD ISO playback?Does it use LSPCon for HDMI?
timecop1818 - Monday, May 6, 2019 - link
Yes, it uses MegaChips MCDP2850 to convert DisplayPort to HDMI 2.0. You can see it on the motherboard photo in the QuickStart manual. What about 3D BD ISO playback? Why wouldn't that work?ganeshts - Monday, May 6, 2019 - link
3D is usually not supported if you have a LSPcon. I have reason to believe 3D is not supported over the HDMI 2.0a ports in the last two Intel platform generations.With the advent of 4K and HDR, the industry has got much more convincing features to make people upgrade their equipment (compared to 3D). Effectively, 3D is dead from an industry viewpoint. YMMV.

great example of a tech killed off by lack of content (i mean good content). too many movies were simply reprocessed without being produced from the ground up with the intent of 3d. the industry tried to charge a premuim for lackluster content with hardware implementations having support and quality issues. not to mention some big problems like focal blur guessing.i really hope vr doesnt go the route of 3d games and 3d movies. but yeah people dont seem to understand that the most important things are affordability and minimizing barriers to entry. also not having an industry clinging to ancient monitization practices helps.

I think it is more about the technology itself. In order for stereoscopic 3D to work well, you need to have most of your field of vision filled by the content. That is easily done in a cinema, where the screen is huge and the ambient lights are darkened and everyone is fine with that. At home, most people I know have their setup with a small TV (37" to 50") and it is in a corner somewhere it makes sense but is out of the way (since the TV may be on a lot, but hardly watched focused most of the time). Only some die hard movie people (like myself) have a large TV (55"+, preferably 65"+) that is not too far away from the main sitting position (couch). But even then, it is a bit too small for 3D to work well and immerse myself in it and I can't really darken everything down as much as in the cinema. And I have never had comfortable 3D glasses. They always either hurt my sides or my nose.VR won't go away as 3D will, since it has a much larger impact in the professional world (engineering, architecture, medicine, art...), but home VR has an uphill battle to fight still.

Honestly I'm kind of expecting 3D to come back again.They are now making fully transparent TVs.
Layer the screens and you can have actual 3D (at least two layers of depth) without glasses.

How would that work? You still need a way to block one eye from seeing the content the other eye sees. Doing it with a parallax barrier requires cost and doesn't work for more than one person without a lot of complications (which increase price, a lot). You also lose resolution compared to full 3D SBS and active shutter glasses.Or do you just mean 3D in a diorama way where you have discreet layers of content? That is not 3D.

Thanks ganeshts.I know it's a dead format, but I would like to use it as long as my TV lasts.
Hoping one day I can get a modern PC that has native HDMI ports (no LSPCon).
Does anyone know of TB3->HDMI adapter/cable that does work?
