GIGABYTE Z170X-UD5 TH Board Features
At the heart, the Thunderbolt 3 element here is going to be the most vital. Support for DisplayPort, up to 40 Gbps data rates over an active cable with TB3, and USB 3.1 at 10 Gbps in one port makes for interesting reading. Supporting HDMI 2.0 (HDCP 2.2) via integrated graphics is also worth noting.

At the ~$200 price point, there are at least two sorts of motherboards – those that are $160-ish base and are boosted up by contents, or $230-ish that are slimmed to meet a price point. The Z170X-UD5 TH is thin on box contents, firstly because it is from the base Ultra Durable line, but also because it may be trying to meet that price point. For example, only two SATA cables is a bit mediocre when the motherboard has six ports, but also at this price we are starting to see USB 3.1 front panel attachments being bundled. You can argue that this is because of the Thunderbolt 3 feature-set, but then I would also request a TB3 or Type-C cable to be included. Unfortunately these can be expensive as well.
For the Z170 platform, GIGABYTE moved the majority of the Ultra Durable line, especially above $150, to a black and gold scheme. Other companies have toyed with gold in the past, either a dull gold or something more akin to copper, but the color here is certainly the right one which contrasts with the black in an aesthetically pleasing way. It has been postulated in the past that gold color schemes sell well in various parts of the world, although I can’t confirm this.
The Z170X-UD5 TH uses International Rectifier IR355x ICs, either 40A or 60A rated, with the high end chokes that are commonly associated with 60A variants (although we’ve seen 40A ICs with 60A chokes before). IR’s parts are often touted as being very efficient, which probably explains the minimal heatsink around the power delivery compared to some of the extended models we see elsewhere. The socket area is very clean, normally an attribute associated with overclocking motherboards, but it is clear that GIGABYTE is using a matte finish on top of the motherboard traces to enhance the aesthetic, along with ditching the Intel specification socket design motifs. The socket area has access to five of the six onboard fan headers – the CPU and WC 4-pin headers are above the socket next to the DRAM slots, a 4-pin SYS header is by the 8-pin power connector, another 4-pin SYS header is by the rear audio jacks and a final 3-pin SYS header is below the 24-pin ATX power connector. The last fan header is a 4-pin SYS header on the bottom of the motherboard next to the front panel header.
Moving clockwise around the motherboard, we have the four DDR4 memory slots using a single sided latch mechanism. This makes the memory easier to remove, especially in the presence of large graphics cards, but does require extra care when installing the memory to ensure both sides are fully in the slot. To the right of the memory are some of the out-of-case functional items – a power switch, a reset switch, a clear BIOS switch and a two digit debug. I tend to use these extensively in our reviews, and can be useful for debugging issues. Next to this is a series of voltage checkpoints, allowing enthusiasts to directly monitor system voltages when the software is not accurate enough. This typically only applies to extreme overclockers using sub-zero cooling, but it is a simple addition on most motherboard designs. Below this is the 24-pin power connector, a fan header, a SATA power connector to give more power to the PCIe slots, and two USB 3.0 headers.
Beside the large chipset heatsink are six SATA 6 Gbps ports, split into three pairs and supporting SATA Express. While no SATA Express devices exist, some front panel bays are starting to come to market that support USB 3.1 ports, suggesting that there might still be some use for these. With the storage ports is an M.2 slot between the bottom two large PCIe slots, and this M.2 slot supports SATA storage and up to PCIe 3.0 x4 based devices. This slot, in PCIe mode, is switched with the bottom PCIe slot which is PCIe 3.0 x4 from the chipset by default, meaning that only one of the two can be enabled in PCIe mode at one time.
Along the bottom of the motherboard is our front panel header, a fan header, two USB 2.0 headers, a TPM header, a COM header and the front panel audio header. The audio header is inside the audio guard zone, which represents PCB separation of digital and analog signals on the board for audio. This zone lights up using LEDs on the rear of the motherboard, but on the digital side to avoid interfering with the audio signal. The audio section itself encases the Realtek ALC1150 audio codec in an electromagnetic interference shield to reduce outside sources of noise but also uses filter caps to improve signal quality. Beside this zone is an EMI shield over the Intel I219-V network controller, although I doubt if that makes much difference to the performance and is purely for aesthetics.
The main PCIe slots also include a PCIe guard, helping the rigidity of the slots when in the presence of large/heavy graphics cards. Normally this is not a problem when the PC is stationary, but there are some horror stories online of PCIe slots being ripped out by large cards when in transport. This fix is designed to help that and reduce RMA issues. The board also has three PCIe x1 slots for good measure.
The rear panel, by virtue of the two Thunderbolt 3 ports both supporting displays, is filled with USB ports instead of the usual display adaptors. We do get a HDMI 2.0 / HDCP 2.2 enabled port, supported by an LSPCon in the form of the MDCP2800, as well as four USB 3.0 ports and four USB 2.0 ports. To round it all off is a PS/2 combination port, the Intel I219-V network port, and the Realtek ALC1150 audio jacks.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives in essence an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.
For reference, the GIGABYTE Z170X-UD5 TH, on our testing BIOS F4, MCT was enabled by default although seemed to work selectively on some of our tests but not others. Also, the FCLK 10x ratio for PCIe was present in the BIOS tested at the time of testing.

romrunning - Friday, February 19, 2016 - linkHey, for your "Quick Board Feature Comparison", why didn't you include the feature that is right in your article's title - you know, Thunderbolt 3? It's a pain to compare the other boards when I don't know if they have TB3 or not.
extide - Monday, February 22, 2016 - linkHe did, although, to be fair, you need to know that having the Intel Alpine Ridge controller listed under USB3.1 implies TB3.
romrunning - Wednesday, February 24, 2016 - linkTo be clear, I would like to know if the other boards being compared specifically support TB3 so that it's more of an apples-to-apples comparison.
Having the Alpine Ridge controller doesn't guarantee the board supports TB3. For example, the Asus Maximus VIII Impact doesn't support TB3. Perhaps this is some type of limitation for mini-ITX boards w/AR controllers; I know the Gigabyte Z170N Gaming 5 has the AR controller but doesn't support TB3. Maybe this is an artificial limit imposed by the mfg, or maybe this is just a limitation of how much circuitry you can stuff into the smaller size.
pikunsia - Thursday, August 4, 2016 - linkHey romrunning, look at this
DanNeely - Friday, February 19, 2016 - linkWhere did all the assorted surface mount parts that normally cover the area between the PCIe slots and elsewhere on the board go to give it the cleaner surface look?
extide - Monday, February 22, 2016 - linkThey probably put a lot of them on the back. Lots of boards have been doing this recently, I have noticed. A lot of what they clean up is actually not so much components, but excess silk-screen.
RazrLeaf - Friday, February 19, 2016 - linkFrom the images, it looks like the motherboard has 2-packs of 2 SATA cables, so 4 total.
tspacie - Friday, February 19, 2016 - linkIs anyone doing TB on a small motherboard? I don't need the fast, external port if I have a bunch of PCIe slots and room for extra disks.
romrunning - Friday, February 19, 2016 - linkSmall, mini-ITX boards only have the 1 PCIe slot. So that fast TB3 port certainly helps if you need it.
alamilla - Friday, February 19, 2016 - linkAlthough Thunderbolt is hardly a mainstream protocol (yet) it is big in the audio and video production industry for it's incredibly low latency.
With this Skylake offering and the recently released X99P-SLI, I'm optimistic Gigabyte will release a Thunderbolt enabled mATX or ITX board for Broadwell-E.
