The AMD X570 Motherboard Overview: Over 35+ Motherboards Analyzed
by Gavin Bonshor on July 9, 2019 8:00 AM ESTASUS ROG Crosshair VIII Formula
The ASUS ROG X570 Crosshair VIII Formula represents its flagship X570 entry onto the market with some very notable features, including a revamped design with a strong focus on performance, and ROG themed aesthetics. First of all, the ROG Crosshair VIII Formula uses EKWB heatsinks which can be connected to a custom water cooling loop for better power delivery temperatures, or as passive cooled. This has been seen on numerous iterations of its Maximus Formula boards created for Intel chipsets. This marks a shifting tide where ASUS seem to have confidence in AMD and the ability of its 7nm Ryzen 3000 processors, by opting for such a premium model for the X570 chipset.
One of the main focal points of the X570 chipset is its native PCIe 4.0 support. The ASUS ROG Crosshair VIII Formula has three-full length PCIe 4.0 slots operating at x16, x8/x8, and x8/x8/x4, with the final x4 coming from the chipset. This allows users to use two-way NVIDIA SLI and two-way AMD Crossfire multi-graphics card configurations. For add-on cards, a single PCIe 4.0 x1 slot is also present. There are also four DDR4 memory slots with a maximum supported capacity of up to 128 GB. Also included are a LiveDash OLED screen, a full metal backplate for a more rigid frame, and ROG armor across the majority of the PCB; not to forget about the swathe of RGB LED zones and the integrated fan within the chipset heatsink. On the rear of the board is a metal backplate which adds reinforcement to keep the board's structure intact.
On the componentry, the Crosshair VIII Formula uses a premium controller set with the most notable inclusions coming on the networking side. An Aquantia AQC111 5 GbE controller with a secondary Intel I211AT gigabit chip offers users dual LAN, but more impressively, ASUS has jumped onto the Wi-Fi 6 bandwagon by including the new Intel AX200 2x2 Wi-Fi adapter. The onboard audio is controlled by the Realtek SupremeFX S1220 HD audio codec. On the rear panel is a wide array of connections including seven USB 3.1 G2 Type-A, one USB 3.1 G2 Type-C, and four USB 3.1 G1 Type-A ports. Users can add to this with one USB 3.1 G2, two USB 3.1 G1 and two USB 2.0 front panel headers, with the USB 3.1 G2 offering one additional port, and the rest each offering an additional two ports per header.
The ASUS ROG X570 Crosshair VIII Formula is a mixture of premium controllers, quality features, and classic Formula aesthetics due to the implementation of an EKWB water block to keep the power delivery cool. This not only adds extra weight to the board but also cost and that is represented with an MSRP of $700.

It's amazing how quickly you run out of PCIe lanes, when you don't have switches to multiplex and translate between PCIe revisions and lanes (e.g. PCIe v4 x2 <-> PCIe v2 x8).I find myself using USB 3.x NBase-T NICs and NVMe adapters, simply because they *do* switch.

Maybe a bit more depth on the power delivery page. I have absolutely no idea how to go about parsing what's there. More chokes is better? What denotes a power phase?A5 - Tuesday, July 9, 2019 - link
+1. Some analysis of that information would be helpful.MrSpadge - Tuesday, July 9, 2019 - link

The controller column includes the total number of phases supported split between CPU cores and SoC e.g. (6+1) = 6 CPU phase and 1 SoC phase. More is *usually* better but has diminishing returns regarding tighter and tighter voltage regulation. Some controllers are better than others (can operate at high frequency e.g. 500KHz v 1000KHz, include other features to improve performance) mitigating the need for more phases.Each phase is a buck converter comprised of a low/high side MOSFET (can be integrated in a single package) and choke. Some controllers can support doubling up the PWM signal to driver more MOSFETs. Doublers can also be added as discrete components if not built into the controller.
Current rating of the MOSFET (e.g. Sic639=40A IR3555=60A) indicates the total power deliverable. MOSFETs are not 100% efficient and vary in efficiency. The more current they provide the hotter they get and the less efficient they become, with better MOSFETs producing less heat for a given current. Thus using doubles can improve temperatures and efficiency without the benefits of the tighter voltage tolerance that *real* phases provide.
Hope that’s helpful!

A lot more detailed explanation: https://en.wikichip.org/wiki/voltage_regulator_mod...bug77 - Tuesday, July 9, 2019 - link
The description for AsRock X570(M) Pro4 says "5 jack + 1 SPDIF". Unfortunately, those boards lack SPDIF and only come with 3 jacks ;)Smell This - Tuesday, July 9, 2019 - link
I'm thinking the *ASRock Thunderbolt AIC* ...https://thunderbolttechnology.net/product/asrock-t...
would cover all your TBT peripheral needs, including optical.

Do X570 boards still need an extra chip per USB port to support USB-C reversibility?The additional expense and needed PCB space were cited as among the reasons why earlier generation boards (IIRC both Intel and AMD) almost never had more than 1 C port; but it was never clear to me if that was an inherent implementation penalty for the C port or an artifact of Intel's tech stack being stalled out and AMD outsourcing to ASMedia which built the chipsets on an ancient (55nm) platform.

Gavin - X370 and X470 only supported PCIe 2.0. The connection between the CPU and chipset was 3.0, but all the ports on the chipset were 2.0.
