The AMD X570 Motherboard Overview: Over 35+ Motherboards Analyzed

Another mid-range board from ASRock is the X570 Steel Legend which blends a good range of features in with solid aesthetics with addressable RGB within its the power delivery and chipset heatsinks. The board sits on a black and urban camouflage themed PCB, with steel silver heatsinks, with elements of black to add contrast. This model is also very similar to the ASRock X570 Extreme4 in terms of components used, feature set, and overall design with the main difference coming via the color scheme.
In addition to the straight-lined heatsinks which makes the board look attractive, is a solid feature set including two full-length PCIe 4.0 slots which run at x16, and x16/x4 due to chipset constraints. This means up to two way AMD CrossFire multi-graphics card setups can be used. In the top right corner is four memory slots with support for up to DDR4-4666 which is very impressive, and these slots support up to a maximum of 64 GB. The storage capabilities of the ASRock X570 Steel Legend include two PCIe 4.0 M.2 slots each with its own individual heatsink, and blends into the actively cooled X570 chipset heatsink quite nicely. Also featured is eight SATA ports with support for RAID 0, 1, and 10 arrays, and ASRock's U.2 kit which is available separately is also supported.
The rear panel on the ASRock X570 Steel Legend is more comprehensive for a mid-range model than the ASRock X570 Phantom Gaming 4, with a single USB 3.1 G2 Type-C, one USB 3.1 G2 Type-A, and six USB 3.1 G1 Type-A ports. A single Ethernet port is powered by an Intel I211-AT Gigabit NIC, and while there is no wireless interface included, an M.2 Key E 2230 slot with inserts included on the IO shield allow for users to install their own. There are five 3.5 mm color coded audio jacks with a single S/PDIF optical output which are driven by a Realtek ALC1220 HD audio codec, a DisplayPort 1.2 and HDMI video output for Ryzen 2nd and 3rd gen APUs, and finishing off the rear panel is a PS/2 combo port.
The ASRock X570 Steel Legend offers users a similar feature set to its X570 Phantom Gaming 4, but with better onboard audio (Realtek ALC1220 vs ALC1200) and utilizes addressable RGB effectively within the heatsinks. This model also uses a straight forward 10-phase power delivery and includes an 8-pin and 4-pin set of 12 V ATX CPU power inputs to provide power to the processor. Price wise, the ASRock X570 Steel Legend has an MSRP of $200, while users in the USA can also get a version with Wi-Fi 6 at a cost of $210.

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.
