X570 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.

    Pretty much this. Modern games on DX12 won't see any benefit unless the game developer bakes in support (which they appear uninterested in doing for cost reasons) and older games run very well on a single modern GPU. AMD and NV are hardly acknowledging SLI these days either and nowhere but at the top end so there is even less compulsion for developers to bother with supporting it. All in all, you're better off not worrying about SLI unless the industry changes direction significantly in the next few years.

    The real question however, is does all this power delivery actually have any practical benefits? If I drop a 3000 series CPU in an X570 board vs X470, can I achieve any additional performance? And what is the power consumption differences in the respective chipsets? That is the type of info I would like to see.
  • PeachNCream - Tuesday, July 9, 2019 - link

    It's a marketng differentiator only as motherboard manufacturers all use the same core components and are quick to emulate one another with similar features. Through branding and obscure features that do not significantly impact computer operation, they search for something they can offer that may encourage you to make a purchase in a very, very crowded field of offerings.

    Solid power delivery for high-performance CPUs is perhaps the farthest thing from obscure marketing features. OEMs do play with marketing BS for differentiation, but the underlying power delivery system is extremely important and can impact everyday operation for these multi-core CPUs.

    At long as it meets AMD specifications, no it won't. If it doesn't meet specifications, then it's a bad design. There's no reason to tout being mediocre or a hair or two above mediocre unless you're running out of unique bullet points for the backside of the box that nobody bothers to read anyway.

    Stock performance will be the same across the board unless the manufacturer royally screwed up and the power delivery has to throttle due to temperatures (which there are some cases of with super cheap motherboards and 8 cores). Doing OC (and PBO is already OC) is where things start to change. More / better phases means less heat output and better voltages (ripple). This can potentially give you better clocks. But most of this is only useful when you start OCing on water or sub zero systems. Air cooled overclocking will hardly benefit at all. And regarding power consumption you can go into a lot of detail. Sometimes more power phases simply destroys efficiency, when they are all fired up all the time. Sometimes more power phases are smartly managed and load balanced to be kept at their optimal efficiency. It really depends on the implementation.

    If you leave everything at stock, then there is no real reason to upgrade
    Most people would think keeping the socket backwards compatible as an upside

    In a desktop the only real reason why we think about power draw going up from 5w to 11w is because manufactures like to keep the cooling block small, and those need a fan
    Chipset fans bring back memories out of terrible noisy days
    Also I remember chipset coolers to be a bit bigger in the past, I'm sure if you're just trying to provide food cooling, without trying to hit that gamer look, then you can cool that chipset without active fan

    If you want to try your hand at OC'ing you should probably want the better power delivery

    And there is no telling if the older boards will also run fine with higher memory speeds
    Guessing they would, at least until the magical 3600, that's not that outlandish high
    And how much that affects performance this time around still has to be tested

    Short story
    You have a Ryzen already, just make it a drop in replacement
    No need to throw out the board
  • Peter2k - Wednesday, July 10, 2019 - link

    Any one that would argue about the electricity costs going up (I've encountered those) should also not that all that shiny bling probably draws more watts then the 6w or so difference between last gen and this gen
  • pavag - Tuesday, July 9, 2019 - link

    I expected benchmarks.
  • sorten - Tuesday, July 9, 2019 - link

    You expected benchmarks on 35+ boards that were released two days ago, and many of which aren't even available at retail?
