Asus ZenBook 14 UM433IQ review (AMD Ryzen 7 4700U, Nvidia MX350)

    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"

    Video "Intel UHD 620 + Nvidia MX350"

    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?

        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.

      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…

        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: https://www.ultrabookreview.com/38004-amd-vega-7-8-mx350-benchmarks/ . 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.

          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.

          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.

    When is this going to be available in the US?

    • Andrei Girbea

      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

    "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.
