System Performance

Not all motherboards are created equal. On the face of it, they should all perform the same and differ only in the functionality they provide - however, this is not the case. The obvious pointers are power consumption, but also the ability for the manufacturer to optimize USB speed, audio quality (based on audio codec), POST time and latency. This can come down to the manufacturing process and prowess, so these are tested.

Power Consumption

Power consumption was tested on the system while in a single ASUS GTX 980 GPU configuration with a wall meter connected to the Thermaltake 1200W power supply. This power supply has ~75% efficiency > 50W, and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real-world values that consumers may expect from a typical system (minus the monitor) using this motherboard.

While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our testbed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.

Power: Long Idle (w/ GTX 980)Power: OS Idle (w/ GTX 980)Power: Prime95 Blend (w/ GTX 980)

The ASUS performs well in our power consumption tests and is marginally the most efficient of the ATX sized X570 models. It also stacks up well against the rest of the AM4 models on test.

Non-UEFI POST Time

Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we look at the POST Boot Time using a stopwatch. This is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows specific features.)

Non UEFI POST Time

The ASUS is one of the fastest AM4 boards on test in our non-UEFI POST time testing, only fractionally slower than its B550-F Gaming. The X570-E Gaming turns the tables here slightly as it sits the best when all nonessential controllers are disabled.

DPC Latency

Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests such as audio will be further down the line. If the audio device requires data, it will have to wait until the request is processed before the buffer is filled.

If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time. This can lead to an empty audio buffer and characteristic audible pauses, pops and clicks. The DPC latency checker measures how much time is taken processing DPCs from driver invocation. The lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds.

Deferred Procedure Call Latency

We test DPC latency at default settings out of the box, and ASUS is certainly doing something right, with some of the lowest DPC latencies we've seen on desktop motherboards.

    I have this board, they just forgot to tell that there is a bunch of bios upgrades in asus website that is causing a lot of errors in people systems, so it is a good thing check the asus forum first to see which ones are the stable bios before rushing into the last one ( using ver 3001 here but there is a 3402 beta already for download in asus website).
    Another thing that bothers me in this mb is the fact that it doesn't have a bios reset button for use when overclocking or fine tunning the memory. You only have an ancient jumper pin and terribly located in the bottom part of the motherboard.
    The chipset sits right under the video card and suck all the hot air from it. My chipset temperatures was around 68ºC in idle with a GTX1060. Since I don't use the computer for gamming, I changed the GTX1060 to the second slot and changed the thermal pad too, and now chipset temp is around 62ºC.
    These are the negative points I found in this board that was not mentioned in the review.

    All new mainboards have issues with crappy firmware. But its starting to get ridiculous with X570 and B550 ones. They sure as hell arent new anymore. Only the Zen 3 CPUs are, and they have been released for a long time as well.
    Yet nothing seems to change or improve.
    I am seriously rethinking of buying an AMD because of that and because of the WHEA issues (not to mention the still not fixed X570 IO issues.
    Guess people (and me) were right still recommending Intel simply because they are far more stable.
  • Qasar - Tuesday, January 26, 2021 - link

    news for you, myself, and some others i work with, have had issues with intel as well. be it bios updates or drivers. to claim intel is more stable, is also false.
    EG, i have 2 X99 boards, after a re install of win 10, for some reason, 6 of the 10 sata ports would not work after installing the latest drivers from the board maker AND intel's site, exclamation point in device manager. went back to both pages and tried a few of the driver revisions on both, i started to search for drivers. finally found ones that fixed the issue. this driver version was not available on either site.
    i have this board, and it has been great for a year now. even with an issue with the SB Z sound card i have, and a bios update that cause it to reboot on its own from time to time, i would still get this board again. bottom line i have had issues with BOTH AMD AND Intel. and would get either or, depending in which has the performance and features i want for a price i am willing to pay. this round, its been amd, and have replaced 3 of 6 comps with amd and ryzen 3000 cpus that were intel.

    So youre comparing ancient boards with new ones?
    Ok.
    You know, my one Z170 board also has lots of issues. But they started over time, because........ its degrading after 5+ years.

    The issues with AMD are filling reddit and other forums. Thats a fact. And its not issues that are because of rare hardware failures that are normal, its because of bugs in software AND hardware design that can be reproduced rather often. In comparison, when the first Skylake had the "768 FFT bug", or the Z87 bug, it wasnt nearly as huge of a problem as the AMD fanboys made it out to be. Plus they were fixed quickly.
    The issues with AMD right now are vast, critical and numerous and some of them have been there for quite a long time (some even since Zen 2). And all you hear are crickets.
    If Intel had those issues, the cries of havoc would be so shrill and loud that even your rose colored glasses would burst into tiny shards. And very justified so.

    But this "users keeping silent/uncritical about serious issues" phenomenon has always been a part of AMD. Even 20 years ago. I fell for it several times myself.
  • Qasar - Tuesday, January 26, 2021 - link

    yes, as while that issue with the sata ports were recent, when i picked up my x99 board new 5 years ago, i had issues then as well.
    the funny part, is EACH person has their own experience with either side. myself, i have had issues with BOTH. it hasnt been just amd, or just intel over the years.
    " it wasnt nearly as huge of a problem as the AMD fanboys made it out to be " the SAME can be said about the intel fanboys with amd, whats your point ?

    while you kind of accuse me of rose colored glasses, the same can be said for the other side as well, again whats your point ?

    if intel does it, its just fine, and ok, but if AMD does it, its a federal offense.

    They managed to squeeze so much projection, prognostication and ventriloquism into a few tight little posts. It's an exceptional demonstration in partisan rhetoric married to denial.
  • Qasar - Tuesday, January 26, 2021 - link

    i didnt know that saying either side has had,and has, its issues was considered to be a demonstration in partisan rhetoric married to denial.
  • Spunjji - Wednesday, January 27, 2021 - link

    @Qasar - I was talking about Beaver M., not you. I agree entirely with you here. 👍
  • Spunjji - Tuesday, January 26, 2021 - link

    I'm impressed by the way you made a claim about forums, threw in the declarative "Thats a fact" (it wasn't, it's hyperbole) and then followed with another statement that *definitely* isn't a fact - it's clearly just your opinion. Very self-confident; Dunning and Kruger offer a salute.

    I also appreciated your completely un-self-aware commentary on how other people have "rose tinted glasses", even as you assume the truth of your casual dismissal of specific Intel issues. To make it extra funny from an outside perspective, you hype up a few other AMD issues you just didn't quite get around to specifically naming.

    Whatever this bit you're doing is, it's very good!
  • Spunjji - Tuesday, January 26, 2021 - link

    Cautiously-worded partisan FUD is still partisan FUD. You jumped from someone's specific anecdotal critique to a generalised one, then used that to bolster an unrelated conclusion.

    I Googled the WHEA issues, and it leads to two types of post:
    1) People gathering data on the issue and noting that it doesn't do any harm in and of itself, and is often fairly trivially solved.
    2) A bunch of similar posts on forums (some from the same users) that look like this: "My (fairly recent) high-spec Intel system was a saint that never crashed, and now my brand-new high-spec AMD system crashes aLl ThE tImE and this is definitely AMD's fault. /ragequit"

    It's possible there's a selection bias here - and I might be missing a serious issue. I just don't really buy the way you introduced these topics.
