ASUS TUF Z390M Pro Gaming & Z390M Pro Gaming Wi-Fi
The TUF Z390M Pro Gaming is the smaller mATX sibling of the above ASUS Z390 Pro Gaming and as a result, features much of the same black and grey design with yellow accents. The main differences between the ATX and mATX sized TUF Pro Gaming motherboards are the smaller model has two full-length PCIe 3.0 slots which run at x16 or x8/x4 and ASUS has only included one PCIe 3.0 x1 slot. The maximum memory the Z390M Pro Gaming supports is DDR4-4266 and the board does offer four RAM slots with a maximum support capacity of up to 64 GB.
Storage capability on the TUF Z390M Pro Gaming M.2 PCIe 3.0 x4 and SATA supported slots with one of the slots being supplemented with an M.2 heatsink. This mATX sized board keeps all six SATA ports which are split into two different sections; three straight-angled ports at the bottom right-hand edge of the board, with three right-angled ports on the right-hand side underneath the 24-pin ATX motherboard power input.
ASUS TUF Z390M Pro Gaming (WI-Fi) Rear Panel
With the only differences between the TUF Z390M Pro Gaming and Z390 Pro Gaming (Wi-Fi) being the latter has an Intel 9560 2T2R Wave 2 supported 802.11ac adapter; take this out of the equation and the rest of the rear panel and specifications are exactly the same. A total of six USB ports comprised of one USB 3.1 Gen2 Type-A, one USB 3.0 Type-C and four USB 3.0 Type-A ports is featured, as well as HDMI and DisplayPort video outputs. A pair of PS/2 ports with one for a keyboard and the other for a mouse sitting at the left-hand side of the rear panel, an Intel I219V Gigabit controlled LAN port and basic three 3.5 mm port powered Realtek S1200A HD audio codec completes the capacity of the panel.
The ASUS TUF Z390M Pro Gaming pricing us yet to be revealed but it's expected that the TUF Z390M Pro Gaming Wi-Fi will command a higher premium with an Intel 9560 MU-MIMO Wave2 Wi-Fi adapter included. The pairing of mATX form factor boards aims at the lower end of the mid-range segment and without too much going on, users looking for a more comprehensive mATX board may look to the more expensive ROG Maximus XI Gene or another competitors offering.

That would be pretty shocking, yeah, but the sheer size of that lump of metal still has me a bit worried. Guess that's what you get when you try to squeeze power delivery for a CPU that (likely) pulls >300W when overclocked into an ITX board (and refuse to use riser boards like before, for some reason).FXi - Monday, October 8, 2018 - link
The power feed also changed with z390 I believe at least in the Asus models it did. The power feed of the 370 was "enough" to drive the newer 9700/9900 but there is a difference there that may impact enthusiasts. I don't think it enough to warrant an upgrade but something to consider.Also people should remember that while it is still a bit of a ways off, wifi is going to change to Wifi6 or 802.11ax starting now and probably seeing much of the changeover during 2019/2020 depending on adoption choices. And there is also pci-e 4.0 to consider next year probably that should be thought about before people do "marginal" upgrades from 370 era chipsets.

Silly thing posted in edit window. Sorry power delivery and other points covered by you. Would have edited if I could have found that optionDanNeely - Monday, October 8, 2018 - link
Other things to look forward to in the next few generations are: Less-hacky USB3.1 implementations (eg this articles speculation that a 10g port will need to eat 2 HSIO lanes instead of 1, and still needing an extra chip to support USB-C). Spectre/Meltdown fixes in hardware. A reduced DMI bottleneck between the CPU and chipset (either just from upgrading the link to PCIe4/5, moving some of the peripheral IO onto the CPU, or both.Valantar - Wednesday, October 10, 2018 - link
Considering that the maximum theoretical bandwidth of PCIe 3.0 x1 is 984.6MB/s, you _need_ two PCIe lanes (and thus two HSIO lanes) for a USB 3.1G2 (1.25GB/s) controller unless you want to significantly bottleneck it. That's not "hacky", that's reality, even if this leaves a lot of bandwidth "on the table" if this only powers a single port (which it rarely does, though, and given that a full load on two ports at one time is unlikely, running two 1.25GB/s ports off two .99GB/s lanes is a good solution).Moving DMI to PCIe 4.0 will be good, though, particularly for multiple NVMe SSDs and >GbE networking.

Splitting the traffic over 2 HSIO lanes is a hack because it'd require something to split/combine the traffic between the chipset and usbport. That in turn has me wondering if the speculation about the implementation being done that way is correct, or if the Z390 has 6 HSIO lanes that can run 10Gbps instead of the 8 that the rest top out at for PCIe3repoman27 - Thursday, October 18, 2018 - link
The implementation is absolutely not done that way. HSIO lanes are simply differential signaling pairs connected to a PCIe switch or various controllers via a mux. The PCH has a 6-port USB 3.1 Gen 2 xHCI, which can only feed 6 HSIO muxes. The back end of that xHCI is connected to an on-die PCIe switch which in turn is connected to the DMI interface. That DMI 3.0 x4 interface is already massively oversubscribed, but it is at least equivalent to a PCIe 3.0 x4 link, which is the most bandwidth that can be allotted to a single PCH connected device.Srikzquest - Monday, October 8, 2018 - link
HDMI 2.0 is available in Asus and Gigabyte's ITX boards as well.gavbon - Tuesday, October 9, 2018 - link
Thank you Srikzquest; updated the tables, obviously missed this yesterday :) - Thanks againHickorySwitch - Monday, October 8, 2018 - link

It says under "Specifications" that the board sports HDMI 2.0[b?]
