GIGABYTE Z390 Aorus Ultra
As GIGABYTE has moved away from their numbering scheme and elected to use a more prominent gaming scheme, the previous Z370 Aorus Gaming 5 which sat in the mid-range of GIGABYTEs Intel range has been replaced by the Z390 Aorus Ultra. Aesthetically not much has changed as both models have integrated RGB LED lighting at various points across the board including the power delivery and chipset heatsinks and the Z390 does include a total of (insert) RGB headers to further expand the RGB capabilities of the board. Just like the Gaming 5, the Z390 Aorus Ultra has integrated 802.11ac Wi-Fi on top of a single LAN port so users can get the best of both worlds when connecting to a network. GIGABYTE also advertises a 13-phase VRM (12+1) so there should be plenty of headroom available for users looking to overclock the new 9th generation Intel processors.
The Z390 Aorus Ultra shares similar characteristics as the Z370 Gaming 5 such as three full-length PCIe 3.0 slots which operate at x16, x8 and x4 from top to bottom respectively. GIGABYTE has upgraded the previous board as the Z390 Aorus Ultra now has metal slot protection on all of the full-length PCIe 3.0 slots. Also included on the board is three PCIe 3.0 x1 slots.
While both the Z370 Aorus Gaming 5 and the new Z390 Aorus Ultra has three PCIe 3.0 x4/2 M.2 slots, all three slots now include a dedicated M.2 heatsink to aid in heat dissipation on the newer Z390 option. The board also makes use of six SATA slots with support for RAID 0, 1, 5 and 10 arrays. Focusing on memory, the Z390 Aorus Ultra has compatibility with DDR4-4133 RAM and up to a maximum supported capacity of 64 GB across four RAM slots.
On the rear panel, there are three USB 3.1 Gen2 Type-A, one USB 3.1 Gen2 Type-C and four USB 2.0 ports. Like the Z390 Aorus Master, there are also two USB 3.0 Type-A ports marked with GIGABYTE's DAC-UP audio boost technology. The Z390 Aorus Ultra has support for 2T2R Wave 2 802.11ac wireless networking and the single LAN port is controlled by an Intel I219V Gigabit networking controller. A single HDMI video output is featured for users looking to utilize the integrated graphics on supported 8th and 9th generation Intel processors and the onboard audio which consists of five 3.5 mm audio jacks and an S/PDIF optical output are controlled by a Realtek ALC1220-VB HD audio codec.
The GIGABYTE Z390 Aorus Ultra is a mid-high end Z390 option which costs $250 aimed towards gamers and enthusiasts looking to make use of multi-graphics card configurations and multiple M.2 storage devices with each slot garnering support for NVMe based drives. A handy LED debugger is also featured meaning users looking to overclock their processors have a handy method of diagnosing failed overclocks as well as POST related issues.

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
Correction:https://www.asus.com/us/Commercial-Servers-Worksta...
It says under "Specifications" that the board sports HDMI 2.0[b?]
