The AMD X570 Motherboard Overview: Over 35+ Motherboards Analyzed
by Gavin Bonshor on July 9, 2019 8:00 AM ESTX570 Power Delivery Specification & Comparison
One of the most talked about aspects of any high-end motherboard lately is the quality of its power delivery system. At a high level, all X570 motherboards have to adhere to a couple of factors, the most important of which is support for the upcoming Ryzen 3950X 16c/32t processor. This means manufacturers needed to work even harder in creating suitable and efficient power delivery systems to ensure full compatibility with the Ryzen 3000 series.
Meanwhile, we're also keeping a look out for any cases where manufacturers may be embellishing their power delivery claims, advertising a board as being more capable than it really is. After some bad history and what has happened in the last two years there, we hope to (and expect) to see less of that with the X570 chipset.
As power delivery is usually one of the most requested items for any of our motherboard content, prior to the launch we reached out to all the motherboard vendors to find out what power delivery systems each of their new X570 boards are equipped with. Below is a table of the official information we have compiled from each of the vendors, with a question mark (?) denotes when we don't have information available.
Please note that this information is self-reported, so until we can review any given X570 board, we're operating on the honor system, trusting vendors to supply honest and upfront information. And we will be checking, and we will be keeping this page up-to-date as more information becomes available.

As we get more information from vendors or reputable sources, we will update the table. As we get more and more X570 boards in for review, we can go deeper into the analysis in each individual review over the upcoming months.

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.
