    Very poor proof reading.
    The Good "fine IPS touchscreen, but not very bright" yet states "At the same time, you’re not going to get a touchscreen with this product"

    Why laptop makers never install good quality touchscreen displays into Ryzen-powered laptops? Is it prohibited by some law?

    Hey guys I do not know if this is possible but could you check how the setup performs with the dGPU only taking care of PhysX ?
    This could be the best performance scenario for games.

      I no longer have this around. PhysiX was set on Auto in our tests, which is the standard-setting, why would changing it to dGPU only make any difference?

      • Chris

        From my experience offloading physx increases performance by about 10% in typical games, found this out when I noticed my old mobo was not Sli compatible. As both gpus won't play together in this way, it might be a clever solution to boost overall performance. I'm not an expert!

        I've never tried it, so I can't comment on whether it makes a difference or not. I doubt it can go past the main problem here, which is the limited thermal module

    Great to see the MX350 vs Vega comparison. There have been some idiots claiming that the Renoir iGPU is comparable to the MX350, and it clearly isn't. Did the games without data simply fail to run at all for the Vega?

    I like the keyboard layout, but good god white on silver is just awful.

    • Andrei Girbea

      May 6, 2020 at 7:58 pm

      Yes, Red Dead didn't start on Vega. For what is worth, though, I wouldn't judge these platforms based on this single review, especially one that's thermally limited. I'd expect both the Vega and the MX350 chips to score higher in better designs.

      I would not be so sure about this. Imagine they dropped de MX350, used a Ryzen 4800U and increased the TDP of the APU to 25 Watts. And for the icing on the cake cooled it properly, so it would sustain clock speeds. Which all would have been possible if it weren't for the dGPU.

      I believe that configuration would come very close to the MX350 – or mights even beat it. Just wait for other OEMs to this. Since the Zenbooks aren't famous for great cooling anyway, other devices could perform way better. Just take a look at the Huawei Matebook D14 with a Ryzen 3500U. They managed to properly cool it and it outperformed even all Ryzen 3700, i5-10210u/i7-10510u, i7-1065G7…

      Can't wait to see the performance of such a device with only 4800U and no dGPU…

      • Andrei Girbea

        A properly cooled MX350 would still beat the Vega8 in games, and by a fair margin. See this, where we compared an ideal Vega8 implementation with the limited MX350 on this ZenBook: . That's on a 4900Hs with excellent cooling, something you're not going to get on any 4800U implementation.

        I agree that other Ryzen U laptop will perform better than this one, but the MX350 is still a more capable GPU.

      • zarkonj

        May 8, 2020 at 12:42 pm

        Alright, it did outperform it – but not by very much. We'll have to wait for some properly cooled, 25-Watt 4800U devices.

        I imagine that it is just easier to cool only this APU without a dGPU and so keep sustained performance. In that article you assume the mx350 will perform better when properly cooled – which for sure is true.

        But I just feel like there will be more properly cooled and thus better performing systems out there, housing only an 4800U APU with Vega8, than there will be lets say 4700U + MX350 devices which can sustain performance. In such a case the gap between Vega8 and MX350 would become smaller – which makes the mx350 questionable in Renoir-Ultrabooks. Intel devices on the other will clearly profit from a dGPU.

      • Andrei Girbea

        May 8, 2020 at 1:06 pm

        Yep, you're right. Ryzen 5 + MX350 would still pair very well imo, but 7 4700U and especially 4800U, not that much.

        I think the MX350 is far more efficient than vega8 because on this laptop we have a poorly cooled MX350 10w vs poorly cooled 25w vega8. And there the MX350 is superior. In the case MX350 10w well cooled vs vega8 25w well cooled, MX350 will surely be superior now therefore imagine a MX350 25w well cooled vs vega8 well cooled. The MX350 will have a good spread over the vega8 in this condition

        Thank you for very useful review. Definitely, Asus could have done better job here.

        There are also rumours about the similarly specced Zenbook UX434IQ launching soon. Do you think it's the same laptop?

      • Andrei Girbea

        May 22, 2020 at 8:39 am

        I think those early rumors reported this UM433IQ as a UX434IQ. If you'll look at the HWinfo picture, it reports this as both UX434IQ and UM433IQ in that BIOS version. That's why I don't think they're going to have a different IQ model for now.

    Once again AMD variant is fcked with that shitty color. Ideapad/Yoga looking way more attractive, especially with USB-C charging/video.

    The part marking on the Micron part in your picture looks up to be LPDDR4 4266 in as 1Gb x 32b. Are you sure it was configured as DDR4 3200?

    • Andrei Girbea

      May 21, 2020 at 9:58 pm

      Pff, you're right, that's LPPDDR4. Thanks, I'll address the article.

      No idea when or even if this will get to the US.

    Hey, I need an answer urgently if you are able to provide it.

    Is the laptop configured in single channel or dual channel? I'm buying the 8gb model with Ryzen 5, so do you think that is in single channel, and is it upgradeable?

    • Andrei Girbea

      June 28, 2020 at 10:31 am

      why not just read the article? The RAM is dual-channel on this configuration, and it's not upgradeable


      July 27, 2020 at 11:12 am

      It is in dual channel, the ram is soldered on and can not be upgraded.

    "The USB-C port continues to be gimped, with just gen2(10 Mbps) data transferring capabilities and no support for video, charging or Thunderbolt 3." Well 10 Mbps would indeed be unacceptable! It's 10 Gbps obviously. I agree the lack of Power Delivery in particular is a bummer. Being able to use a USB power bank or smaller charger on the go (and not being stuck with a proprietary charger) is convenient.

    Apparently now in (only in) Light Grey finish:

    Better than Icicle Silver?

    • Andrei Girbea

      Seems about the same. Still a silver keyboard with with lighting

    I'm not a fan of brushed aluminium and they moved it from the top lid to the keyboard deck. The overall color scheme looks pretty bad to me. It seems like they went a step backwards with this design. Looking at the images taken with a dark screen in a dark room and besides the backlight bleed, I also noticed dead/stuck pixels (a red dot and some other white dots – which could be specks of dust but the red one certainly isn't). Almost every Asus laptop I've seen has had dead pixels and it's too bad because they usually make decent laptops but the screens are a letdown.

    Great review, i'm hesitating get this one but for CAD 1050 here (650 euro) price is going down it's good price with the discrete graphics, or wait for 4800Us which i might not have time for. I need good performance, i currently run 2 ext monitors natively on my 2018 inspiron 7370 i5-8, 1 x 2.5k hdmi and one 1080p using a usb-c dongle, browser open with at least 70 tabs, real time stock trading platform with lots of streaming data, and it has held up well with 8gb ram but have to restart every day obviously, except it's slow for managing photo libraries and handling 4k video (8gb ram). I also want to get more into video and photo editing, so would the mx350 help me much vs the standard 4700u without discrete graphics but more RAM (prob 24 or 32gb)?

    1- i understand the lpddr4 is slower than DDR4? is that a factor against this machine? some reviewers say it is
    2- Although usb-c does not support video out or PD, would a usb-c or usb 3 dock that supports 2 or 3 monitors such as this work? or does the pc still have to send video out for the dock to work. I assume these docks have drivers and chips to do that? but i'm not sure

    The others i am looking at are hp envy 15 (video and PD on USB c), acer aspire 5 144 (no video and PD on USB c), Dell 7405 2 in 1. They all have 1 or 2 sodimm slots upgradeable, but with the Asus i wouldn't probably want more than 16 native already dual channel…

    I ordered this laptop 3 days ago and it looks very good for this money (~1000 EUR), but you should put this in bold "that frustrating silver keyboard with white backlighting" with UPPER cases. I bought it from PCgarage .ro and guess what? : returning it is not allowed for juridical persons. For a normal person, that keyboard cannot be used because you can't distinguish the letters in grey with a light grey letter color. And I don't intend to start learning blind-typing.

      October 29, 2020 at 6:08 pm

      So I'm not crazy :) Very few others mention this issue, but it's something that truly bothers me on modern laptops. I found that turning off the illumination during the day helps, and only activate it during the night.

  14. Marius

    October 29, 2020 at 6:59 pm

    @andrei girbea you're not crazy at all. And I'm very angry on the seller that I cannot return it just after 3 days because stupid return policy.
    Thanks for your advice, I'll try it.
    I have complained to Asus for this problem.
    Keep us the good reviews!

    Really great review and would have to agree with all the points made here. I have recently purchased one of these to replace an old Lenovo T420 which broke beyond economical repair (i7, 16gb ram, SSD, discrete nvidia graphics)

    I needed a portable notebook which could be used for a wide variety of things with an emphasis on photo editing (Adobe Light Room) and also some music production\post production editing software along with the usual day to day stuff i.e. office software, web browsing\youtube and some light gaming.

    The thing that annoyed me beyond anything is the soldered ram which is just inexcusable, not even the crappiest laptop of 10 years ago came with this.
    At the time of purchasing I could only find the 8gb model so here we are groan groan….
    Then there is the keyboard illumination \ colour choice which although doesn't bother me as much as some it IS a thing. But more annoying to me is the location and size of the enter key for example.
    The hidden number pad in the touch pad is quite cool though.
    Also really miss the forwards and backwards buttons of the old Lenovo's when web browsing

    Other than that superb laptop and whilst you could further knit pick (thermal design I'm looking at you) I think those points above are the biggest gripes with this or at least for me. Other than that great laptop, love the display and seems well made \ feels solid. Performance so far has been ok but would of still loved more ram or the option to actually upgrade!
