    According to the HWINFO64 image the memory is LPDDR5-5200MHZ

      True. I double-checked. For some reason, Windows reports it as LPDDR5-6000, and other tools as 5200.

        LPDDR5 6000 declared in psref by Lenovo…it's fail.

        Today, taking such a powerful laptop with 16GB (only 12-13GB is free under W11) is simply ridiculous. The 32GB version is inadequate considering retail prices for added 16Gb ram (32GB DDR5 5200 costs about $150-170). Not to mention that there is simply no version with 64GB from the factory…

        In review does not post a screenshot from the AIDA64 Mem & Cache benchmark, but other review do. And there you can see that this model with 12700H (but not with the slow AMD Zen3+ memory controller – always, even in R9) gives out simply phenomenal for 99% of models 2022, the result in reading/copying/writing is more than 80 GB/s, but still falls short to a possible level even lpddr5 5200 with 128 (4×32) bit bus. Thus, this laptop is an almost ideal "system unit" for working in Photoshop when good 30 bit 4k monitors are connected, because Photoshop is maximally dependent on memory speed. Like the built-in igpu when working through Optimus, when system memory is used as a video frame buffer, shared by resource between all devices and OS/software.

        Therefore, I do not recommend this model with an AMD processor to those who want to work with it in Photoshop. Loss in memory speed more than 1.5 times by real tests. Basically, I don't recommend AMD versions for Photoshop until they finally fix their on-chip memory controller, reaching the Intel level, which is faster with DDR5 4800 than AMD with lpddr5 6400 with the same 128-bit memory bus..

        Well, I don’t like the fashion of non-standard screens in resolution, instead of 4k. This leads to the fact that it cannot be switched in hardware to fhd mode (4 pixels to one), without any turbidity on the screen, since 3072x is not divisible by an integer by standart 1920. Which also leads to some blurring when watching video in both 1080p and 2160p. Neither this nor that. And fhd resolution drastically increases fps in older games and increases battery life when you can sacrifice high ppi in text by switching the screen to 1920×1200 instead of 3840×2400 for example. 120Hz 4k screens have been around for 2 years now on market. For me, today only they are relevant in high level laptop models, since they are universal for both work and games in fhd, when slow (and there are always -35-40% compared to desktop ones) mobile discrete chips do not pull out stable 60fps+ in Ultra quality..

        Thank you Andrei for review. You have significantly completed the overal picture, where there were gaps in other reviews. Through joint brain efforts, we get the most complete picture of what manufacturers are selling us.

    Thanks for this great review as always, looks like a great pro laptop

    The performance on battery is pretty bad on this thing (both on battery saver and balanced profile). Like would lag horribly when light gaming, until you plugged it in. Atleast when I tested the Ryzen 6800hs version of this laptop. But I believe same holds true even for this intel version.

    Are there any (Ryzen 6000) laptops that can get full performance or close to it, even while on battery?

      The performance on battery wasn't that bad with this unit, but still, around half of what you get plugged in. That's standard for most such laptops. I don't have a top of which options perform well on battery power with demanding loads, you'll have to go through the reviews and checks the gaming performance on battery section at the end of the Hardware and Performance chapter in each review.

        I see.

        How about thin and light laptops with dGPU that don't have slow response time panels that ghost, are there any?

        Afaik, only thick/heavy 165hz gaming laptops and maybe the rare few oled ultrabook (no dGPU here tho).

        There's the 2022 models of the g14/razer blade I guess, but they're still kinda pricey.

        Hoping when next gen rtx4000/Ryzen 7000 mobile release, it'll push the price down of these last gen products.

        The G14 is the better such option

    Unfortunately i cannot recommend this unit. I will return mine after 1 day of fiddling around with it.
    It smelled like plastic on the bottom around the fan area and where the air gets sucked in.
    I was away during Win11 install, came back and it was hot as an oven – noticed that the fans were not on – there should be something there to protect the unit from doing so. I dont think this is doing any good.

    The speakers are "OK" – not bad, but could've been better in a pricetag like this. My unit was overheating ALOT during installing and just basic browsing and youtube. Temps on the cpu went up to 104 degrees.
    The feeling of the keybey was ok- but as someone being used to better keyboards it really lacks those that extra travel – so not really the best feedback while typing.

    The case is super though, the overall look is ultra premium and the screen is a delight. Installing Win11 on this Notebook was a nightmare – no touchpad working – no wlan working- no bluetooth – was quite the experience – so if you plan on buying this – get yourself prepared for along installation routine (except youre tagging with a windows option).

    Fans were not very loud – max 45-46 db during max load and sometimes really barely audible and off at some points. The battery did something really strange and i would call this faulty as well -> Started with 100%, always on ac power, after one day the maximum was down to 96%. What is that?

    That is a skip for me.

      //Started with 100%, always on ac power, after one day the maximum was down to 96%. What is that?

      Or, under load, there is not enough power and the laptop starts quietly, as in some series it takes the missing power from the battery (thus killing it faster) or the poor quality of the battery cells.
      I can say from my own experience that if a laptop hangs on the power supply 100% of the time, usually self-discharge up to 96% from 100% on a calibrated battery of normal quality (especially a new one, only from the factory) appears no earlier than 10-12 days later.

      I have a 4.5 year old 9-cell Sanyo (94Wh+) battery in an old Thinkpad, bought in China in early 2018 to replace an old 6-cell battery that lasted almost 7 years. This battery already has a capacity wear of more than 35% by the summer of 2022, but even it self-discharges from 100% to 95% not earlier than in a one week. And new at the beginning of 2018, it self-discharged to 95% from 100% for more than 2 weeks…

      Therefore, if this is not a quiet replenishment of the laptop with the missing power from the PSU using a battery, it was definitely defective in your copy. And most likely the laptop itself was defective from the factory.

      I wonder how it passed the Lenovo quality control at the factory then? And did a copy of it pass at all?

    What to expect from a badly designed product.
    Any performant system needs to have at least 4 proper cooling vents, this has just under screen vent which is clearly not enough for the machine performance.

      this is thin lightweight chassis. That sort of cooling module cannot be fitted in this sort of product, so let's try to be reasonable in our expectations and comments

    I bought this laptop and I love the size and weight. I bought the option with the i7 and the touch screen.
    But I had to return it even though the screen was beautiful, I could not handle the glare of the screen.
