Case - Legion 7 with aluminum chassis
Lenovo opts for a gray (Storm Gray) aluminum case with matte, smooth surfaces for the Legion 7. The case follows Lenovo's Legion design scheme: The lid isn't flush with the back, but the latter extends a few millimeters beyond the lid's edge instead - in the case of our test device, it does so by about 18 mm. The battery is firmly built into the unit, and there is no maintenance hatch. The bottom cover has to be removed to access the internals. More on this later.
While the laptop's design is fundamentally discreet, it can still attract attention. Lenovo has installed lighting elements (LED strips on the bottom edges, illuminated air vents) that run in sync with the keyboard lighting. The light show is joined by the illuminated "Y" within the Lenovo logo on the lid's back.
The laptop doesn't reveal any workmanship and/or stability flaws. The gap dimensions are correct, and no material protrusions can be detected. The base unit has sufficient rigidity. The lid can be twisted a bit, but the whole situation is completely within the limits. The tight hinges keep the lid firmly in position and hardly allow it to wobble. The maximum aperture angle is about 175 degrees. A one-handed opening of the lid is possible.
Within our comparison field, the Legion positions itself in the midfield in terms of dimensions and weight. It's slightly larger and heavier than the 15.6-inch competition, but it keeps the 17.3-inch competition at bay.
Connectivity - Thunderbolt isn't offered by the Lenovo laptop
Four (3x USB-A, 1x USB-C) out of the six USB slots work according to the USB 3.2 Gen 1 standard, number five and six (USB-C; left side, rear) according to the USB 3.2 Gen 2 standard. The latter support Display Port via USB-C. This provides the laptop with a total of three video outputs (HDMI, 2x DP).
The USB-C port at the back also supports Power Delivery, which allows charging the battery using a USB-C power adapter. According to Lenovo, a 45-watt power adapter (20 V, 2.25 A) is sufficient to charge the battery in standby, hibernation mode, or when turned off. Charging the battery when the device is on requires a 65-watt power adapter (20 V, 3.25 A) at the very least. Fully supplying the laptop with power isn't possible, since a maximum of 100 watts can be transferred via USB-C.
The ports are distributed across three sides of the laptop. The majority of the ports are located at the back of the device. As a result, connected cables run to the back and don't get in the way. The illuminated labeling of the rear ports deserves praise, since it makes it much easier to plug in a connector without looking.
Communication
The Killer WLAN module carries a chip (AX200) from Intel that supports the 802.11a/b/g/n/ac/ax standards. The transfer speeds determined under optimal conditions (no other WLAN devices nearby, short distance between laptop and server PC) range from decent to good. Wired network connections are handled by a representative from Realtek's well-known RTL8168/8111 family. It performs its tasks smoothly.
Webcam
The webcam (0.9 MP) produces images in a maximum resolution of 1280x720 pixels. Moreover, there are issues with color accuracy. With a color deviation of about 17, the target (Delta E less than 3) is very clearly missed.
Accessories
The laptop comes with the usual documents: A quick-start guide and warranty information.
Maintenance
The bottom cover has to be removed in order to access the interior. To do so, all screws on the underside of the device are removed. Afterwards, the bottom cover can be removed with the help of a flat spatula or a grout finishing tool.
Warranty
Lenovo grants the 16-incher a three-year on-site warranty. Extending the warranty to four years would cost about 50 Euros (~$61).
Input devices - Keyboard with RGB lighting
Keyboard
The flat, smooth keys of the backlit chiclet keyboard have a short travel and a clear pressure point. We like the key resistance, and the keyboard doesn't yield when typing. The brightness of the key illumination (three brightness levels) is controlled using secondary function keys. All in all, Lenovo delivers a keyboard that is suitable for everyday use here.
Touchpad
A multitouch-capable ClickPad (about 12 x 7.5 cm) serves as mouse replacement, and it also responds to inputs in the corners. The smooth surface doesn't restrain fingers when gliding. The pad offers a short travel and a clear pressure point.
Display - 165 Hz IPS in the 16:10 format
The brightness (469.4 cd/m²) and contrast (1,287:1) of the matte 16-inch display (2560x1600 pixels) are very good and good, respectively. The 165 Hz panel offers fast response times and doesn't show any PWM flickering.
The display supports G-Sync (Nvidia) and FreeSync (AMD). These technologies dynamically adjust the refresh rates of the display and GPU in relation to each other. This is intended to create the smoothest image possible - especially in computer games.

The display shows good color reproduction out of the box and meets the target (Delta E less than 3) with a color deviation of 1.45. In addition, it doesn't suffer from a blue tint. Calibration can be used to achieve improvements. The color deviation drops to 1.16, and grayscales are displayed in a more balanced way. The AdobeRGB (73%) and sRGB (94%) color spaces aren't completely reproduced.

Performance - Cezanne meets Ampere
The Lenovo Legion 7 16ACHg6 brings every modern game smoothly onto the screen and also cuts a fine figure in all other application areas.
Test conditions
The laptop offers three performance profiles (Performance Mode, Balanced Mode, Quiet Mode) you can switch between using a key combination ("Fn" + "Q") or the preinstalled Lenovo Vantage software. We used the default "Balanced Mode" profile. In addition, we also ran some benchmarks under an active "Performance Mode" profile.
Furthermore, the Vega 8 iGPU integrated into the processor is turned off. This means that the laptop isn't working with Nvidia's Optimus graphics switching solution. The iGPU (and therefore Optimus) can be enabled through Lenovo's Vantage software ("Hybrid Mode") - this has a positive impact on battery life.
Overclocking
The laptop's BIOS hides options to automatically overclock the CPU and GPU. In addition, it's possible to manually adjust the GPU and graphics memory clock speeds. We decided against the latter and only tested the automatic overclocking of the CPU and GPU. The corresponding benchmark results can be found in the comparison tables - identified by the "Performance Overclocking" label.
Processor
The CPU part of the Ryzen 9 5900HX APU (Cezanne) consists of an octa-core processor that operates at a base speed of 3.3 GHz. An increase up to 4.7 GHz is possible via Turbo. Simultaneous multithreading (two threads can be processed per core) is also supported.
The CPU tests of the Cinebench R15 benchmark are processed at 4 to 4.2 GHz (multithread) and 3.6 to 4.7 GHz (single-thread), respectively. On battery power, the CPU runs at 2.7 to 3.5 GHz (multi-thread) and 2.2 to 3.5 GHz (single-thread), respectively.
We verify if the CPU Turbo is also consistently used when plugged in by running the Cinebench R15 benchmark's multithread test in a continuous loop for at least 30 minutes. Turbo is used to a moderate extent. The "Performance Mode" profile results in an increase in clock rates, while additionally activating the automatic CPU overclocking only provides a minimal performance boost.

Storage
Lenovo equips the laptop with two 1 TB NVMe SSDs (M.2 2280) from Western Digital. However, the SSDs don't form a RAID array. One of the two SSDs serves as system drive, the other as data storage. Their transfer rates are very good.

Graphics card
The GeForce RTX 3080 laptop graphics core is Nvidia's current top model high-end GPU. Laptop manufacturers can determine the TGP and therefore the maximum available computing power of an RTX 3000 graphics core quite freely within the limits defined by Nvidia (overview of all RTX 3080 laptops including their TGPs). Lenovo uses the maximum of 165 watts specified by Nvidia (150 watts + 15 watts Dynamic Boost).
The "Balanced Mode" default profile operates with a TGP of 120 watts, and the 165-watt TGP is only implemented when the "Performance Mode" profile is active. A look at the metrics of our The Witcher 3 test reveals that Dynamic Boost is used sparingly if at all. For cross-checking, we ran the "FurMark" tool on its own and were able to measure the maximum TGP of 165 watts.
The 3DMark results are at the expected level. The "Performance Mode" profile results in an increase in graphics performance, and activating the overclocking function boosts the benchmark results a bit further.
The RTX 3080 can access fast GDDR6 graphics memory (16,384 MB). The Vega 8 graphics core integrated into the processor is disabled by default, but it's possible to turn it on.

Gaming performance
The laptop brings all the latest games smoothly onto the screen. Usually, the full display resolution (2560x1600 pixels) and high to maximum quality settings can be selected. Higher resolutions (an appropriate monitor would have to be connected for this) can also be handled by the GPU.
Compared with the RTX 3080 laptops tested so far, the Legion 7 does very well and delivers frame rates above the average. The "Performance Mode" profile increases the frame rates, and the automatic overclocking results in a small performance increase in some cases.

In order to verify whether the frame rates remain largely constant over a prolonged period of time, we let the game The Witcher 3 run for about 60 minutes at Full HD resolution and maximum quality settings. The character is not moved. A drop in frame rates wasn't found.
