The Legion 7 16ACHg6 brings all the latest computer games smoothly onto the matte 16-inch display (2560x1600 pixels, 165 Hz, IPS) in the 16:10 format. The Ryzen 9 5900HX APU and the GeForce RTX 3080 laptop GPU can be overclocked automatically.

Why didn't you test the RAM latencies and speeds? It this point it is a know fact that Legions have problems with RAM performance.
test the ram? they dont even know of the icue power consumption at idle apparently ;D
Great and powerful machine, amazing job from Lenovo this year. It literally crush competition. Fans on my my laptop (same model) doesn't produce that annoying sound you mentioned, luckily and RAM modules on Legion 7 doesn't suffer from slow Latency like on Legion 5 Pro.
Excellent review!
However I notice the idle power draw is a lot higher than it should, in other reviews it's said that the icue RGB software draws close to 20W by itself, can you re test the battery life with the icue process disabled?

it is a case only for legion 5 pro, I believe.
Don't buy this laptop.. Is very expensive and the build is not good, the lid on my legion broke without even using it so much.
The cooling is not working is very loud and i have to use external cooling to play any newer game, by hes own cooling.. He will just shut down.. I'm very disappointed.. I lost almost 2000 euro on a device that is not working
RAM issues is NOT a Lenovo/Legion problem, it's an AMD Ryzen problem.
It's the CPU that is sensitive to RAM timings. Lower timings gives better performance and newer higher density modules perform worse.
For optimal Ryzen performance you need low timings, 4 bank groups, memory modules in 2Rx8 preferably and not 1Rx16.
Was expecting a fully aluminum unibody, but instead it is a shell with black plastic inner structure. Shame. The 7 slim should be far sturdier in comparison then.
Will there be a review of the ideapad 5 pro 16?

I am also waiting for this laptop. Some shops are selling it but only Intel versions.
anyone aware when it will be market in india ?
This laptop looks surprisingly well.
Display has no downside and they actually payed attention to minimum brightness which most companies do not!
Also speakers are surprisingly way above average.
Slightly smaller screen compared to an 17.3inch and being lighter will make it easier to carry it around and battery life is very good for a gaming computer. Im impressed tbh

This is the 2021 model. It has different hinges design.
U have an old model or u made a mistake and damaged it yourself.
The final scores are simply absurd! 85% for keyboards, while the cheap IdeaPad has 89%? What do the reviewers of this site smoke? Or how can you rely on their assessments if they are distributed outside of any single absolute scale accepted by the editorial board required from all reviewers? What is the point of this assessment, if all people write who owns the cheap IdeaPad and Legion, that the keyboard on the latter is sharply better tactile?
Going further - the reviewer praises the screen for its high DCI-P3 / ARGB coverage, not a word or a word from an obvious problem for ordinary buyers who will definitely not do any hardware calibration, and even this will not help in the software that waits for the sRGB / Rec input .709 color space and knows nothing about Windows / Linux color management system. But the excess of sRGB space, which is obvious with such ARGB and DCI-P3 values, leads in practice to poisonous (oversaturated) colors in software showing sRGB content and thinking that the input is sRGB content in Rec.709. Red, oversaturated faces and poisonous green grass in the frame are the result of exceeding the coverage of sRGB space. And all this is omitted in the review! It's good that when you turn on the AMD embedding, there is a built-in sRGB autocalibrator that affects all software at once in Windows, but again it depends on the accuracy of the data in the EDID panel. And this depends on the accuracy of the calibration at the factory (secondly, it floats over time, and AMD does not have an EDID editing mechanism for this autocalibrator)
Versions with Intel do not have an EDID autocalibrator at all, as AMD does. NVidia doesn't have it either. Keep this in mind when choosing a platform.
On the other hand, the Intel version has 2 TB4.0 (USB4.0) ports and a faster memory controller in latency (almost 1.5 times), which is again omitted in the reviews, and in all of them.
Why don't notebookcheck reviews use the AIDA64 memory test module, which measures cache and memory latency? The difference between Intel and AMD in favor of Intel is radical in atomic read / write and copy operations. But ordinary people, of course, are not aware of this ...
Panel too slow by response - 14ms in B2W test! It not 165Hz 100%, it is 90-100Hz panel as max.
Native contrast too low!
2560x1600 is ok for 3080, but new game's releases put 3080 in low fps and playing in 1920x1080 not possible without loss in picture quality. 2560x1600 not integer compatible with 1920x1080(1200). 4k fully compatible 1920x1080=4k/2. HP install in Omen 2021 4k/120Hz panels. It right desicion!
In surfing and office 4k panels have better ppi and more sharp picture!

Yes. AMD have huge latency problem with mobile cpus series (84ms+ vs 52 ms for Intel in average). Intel memory controller in cpu about 1.5 times faster atomic read/write and copy operations in real applications.
During the "Overclocking" portion of the review you mentioned that the laptop's BIOS hides the options to automatically overclock the CPU and GPU. Is there a way you were able to unhide the option to automatically overclock in the bios, i think it's hidden on my laptop as well.
What's up with 3d benchmarks? does that mean Asus is better with the i9 cpu?
When "experimenting on my new machine I got hold of the wrong AMD chipset driver. This resulted in a few BSOD's before realizing the error, just unistalled this from Windows CP and Voila! (Use only manufacturer supplied drivers...)
Had a little difficulty getting the correct version of AMD Adrenaline software (also due to "user glitch:Me") Again, important to use WinUPD and/or Manufacturer drivers&software (but no trouble w/ nVidia's drivers, they work fine as this is the discrete GPU).
I recomend using the 'Terminate-icue'-software (on Github) for automatically disabling iCue-service start from boot saving battery + makes "Rainbow" colors on statup go away...
Also: Thanks to 'NikoB' for pointing out that color calibration is useful!
Battery is good for 4 h 33 m of watching Netflix (via wifi) on Low power mode w/ internal graphics ((Hybrid Mode) and max battery saving: 4h33m
Actually very pleased and happy w/machine!

Maybe you should check out LEGION FAN CONTROL software...
ALL laptops will get hot when playing games, most ppl use headphones Also some kind of laptop stand for more cooling.
There is also a software (above)
Complaining on a broken lid is a little funny... But sad for You; Treat it better next time, friend.

For noise levels above 40dB, no headphones will help. And here is all 45+...
It is for this reason that it is always ridiculous to read about "gaming laptops" that cannot be a priori, if we speak in terms of the ergonomics of the working (game) place and comfort when using in several hours. On a desktop computer, you can independently put a huge radiator and 140mm+ cooler at low speeds and even water cooling for CPU or GPU, doing work and games comfortable in noise (almost silent). In laptops, this is a priori - only the radiator in my tower weighs like half of the "game" laptop.
My processor consumes more than 125W in overclocking mode, but I don't hear it at all for hours even at a load of 100% for all cores. Because the massive radiator and 140mm cooler on 900RPM is enough to remove heat from it. Moreover, it works so stably for years..

What exactly is your opinion for 40 ~ 43 dB, please? I have listened to quite a few notebook noise samples on Youtube etc. while always a bit exaggerating the loadness compared to the reviewer's voice. From that, 40 ~ 43 dB seems still well acceptable without headphones. Not silent, of course, but similar to wind. Of course, the kind of noise varies from device to device; it is more unpleasant for some devices. While there is no doubt that less than 37 dB one can achieve for a dGPU desktop is rather silent, I think your characterisation of 40 ~ 43 dB might be exaggerated. For 45 ~ 65 dB, you may well be right but 40 ~ 43 dB deserve your better justification.
Hi I was wondering if someone could help me should I buy the amd 5900hx or Core™ i9-11980HK de 11ᵃ?
