Final Words

AMD APUs are usually competitive on price, but, not on performance, when compared with Intel solutions. Consumers looking at the AMD A10 Micro-6700T in the Compulab fitlet-XA10-LAN might be disappointed at first glance. Surprisingly, the Compulab fitlet-XA10-LAN packs a lot of punch for its size. Compulab's ability to unlock the TDP with its thermal design gives a great performance boost to the system. In fact, the fitlet-XA10-LAN manages to surpass all equivalent Bay Trail and Braswell systems in almost all benchmarks.

The four gigabit LAN ports of the unit are the real attraction. The FC-LAN FACET module enables the fitlet-X to transform into a compact, yet powerful network appliance. We tested out the unit with an installation of VyOS and configured it as a router. Cursory benchmarking indicated a NAT throughput of more than 840 Mbps.

The two kits provided by Compulab gave us the opportunity to evaluate different thermal solutions for industrial PCs. The heat-sink lid was created by Compulab to make the thermal performance of the fitlet-XA10-LAN better under heavy stress. However, it does increase the height of the unit and negates the compactness aspect. Compulab's new solution of having a different coating for the original aluminum top panel maintains the original dimensions of the unit. Even though the thermal performance suffers a bit compared to the heat-sink lid, it does prevent the unit from getting thermally throttled.

Prospective consumers need to keep in mind that this is an industrial PC, and the SoC and motherboard configuration mandate that only one DDR3 1333 MHz SO-DIMM can be used. Consumers are also stuck with the outdated mSATA SSD slot. That said, mSATA will probably continue to be supported for some time to come in the industrial PC market.

Compulab has an interesting suite of solutions for various industrial computing applications, and the fit-Uptime UPS targets a niche within that. The UPS seems like an attractive option for small-scale industrial PC rollouts. Addition of intelligence (either via network or USB connectivity) would help widen the appeal of the UPS.

Coming to the business end of the review, Compulab's fitlet-XA10-LAN is a unique computing platform. Consumers looking for a compact x86 PC with more than two LAN ports do not have any other options without sacrificing quite a bit on the form factor. If size is not a concern, Compulab has more powerful passively-cooled platforms with support for multi-LAN cards. These include the fitlet-T (AMD Steppe Eage GX-424) with support for up to 5 gigabit LAN ports, the IPC2 (Haswell/Broadwell Core-i7 U-Series) with support for up to 6 LAN ports, and the Airtop (up to Xeon E3 v4) with up to 6 gigabit LAN ports and an option to add 4-6 more with a PCIe card. For specialized applications, Compulab also provides FACE modules with quad PoE 802.3af ports and dual SFP+ optical networking ports. These FACE modules are compatible only with the fitlet-H and fitlet-T.

Given the usual premium associated with industrial PCs, the $315 price point for the barebones configuration of the fitlet-XA10-LAN is quite reasonable. That said, we would like Compulab to explore options to make the thermal performance even better while maintaining the current dimensions.

    This may be a naive question, but would this work as an HTPC? I would love a fanless solution for that and this seems to offer decent performance.

    h.264 8bit 1080p, it could work but dont expect super high bit rates to work.

    The ancient Zbox Nano AQ01 with an A4-5000 runs my 1080 display flawlessly - never a decoding single while streaming, including every H265 file I've tried.

    Old low power cores lack in ST performance so interfaces don't always "snap", but this thing should have no troubles at all with FHD TV.

    Performance-wise it could be used as an HTPC. That said, you'd be better off considering a different variation of the fitlet unless you have a pressing need for all the networking ports.

    Caveats: The fitlets I had got VERY hot. I found the same results over multiple units and more than one variation of the fitlet, so I don't believe it to be a one off issue. I put them on top of mesh shelving and ran a fan on them as they would discolor the surface of the shelve they sat on over time. They had shallow fins on the top, so I believe they were second revision. The new heatsink may fix this problem.

    That all said, you'd probably be better off looking at some of the other offerings from the same company. My experience with the Intense-PC3 and Intense-PC4 have been very positive. They aren't as small as fitlets, but they are still smaller than many consumer grade routers and they don't have the heat issues.

    Correction - I've had positive experiences with the Fit-PC3 and Fit-PC4. Haven't had the pleasure of using an Intense-PC.

    An Intel NUC might not be fanless, but I'm damned if I can ever hear it, and would be a much better HTPC. You could even consider an Intel compute-stick.

    look at the Minix NEO U1 - fanless; 4k, 60fps, 10bit, HEVC
  • raddude9 - Thursday, April 21, 2016 - link

    I would look at a different model of the Fitlet for HTPPC purposes. They have a version with just one Ethernet port for $15 less and one with the slightly slower A4 Micro-6400T chip for $69 less. Both of those probably put out less heat so would be more suitable for HTPC applications.

    6400T is indeed significantly lower cost than 6700T, but for a given workload the 6700T would be lower-power since for a given frequency it can run at lower core voltage.

    Youy might want to consider a Giada F300. Fanless (whole chassis is a heatsink), i5 - great unit allround.
