In a previous test, Lenovo had seduced us with its Legion 5 Pro, a powerful and relatively accessible laptop PC, but very bulky, like most models gaming. With the Slim 7, the manufacturer is aimed at those looking for a thinner, lighter and more sober computer, for games of course, but also for work. Indeed, with its dedicated graphics card and one of the best processors of the moment (the AMD Ryzen 9 5900HX), the Legion Slim 7 should be able to tackle all demanding jobs, especially those of graphic designers and videographers.
This PC costs € 2,099 when it is released, but other cheaper versions of the Legion 7 exist, equipped with Ryzen 5 or 7.
Here is his full test, and the opportunity to see if such a thin chassis does not risk limiting performance to avoid overheating …
The chassis of the Legion Slim 7 is decidedly sober and does not take on character gaming at first sight. Here no marked lines, huge logo or leds of any kind; simply a matte black metallic chassis that should satisfy many users. The coating, on the other hand, retains fingerprints and it will therefore be necessary to wipe it off regularly.
The keyboard and touchpad are of good quality and responsive. A numeric keypad is present on the right side, while a fingerprint reader has been integrated into the on / off button which overlooks the whole. The Fn key is associated with some particular combinations: Fn + A changes the different operating modes of the PC (max performance, balanced mode or energy saving), Fn + R sets the screen to 165 Hz or 60 Hz, and Fn + Space applies different saved backlight profiles.
Indeed, the keyboard has an extensive customization thanks to the Corsair iCue software. It allows, among other things, to modify the backlighting key by key, to change its colors or to apply various lighting effects.
Despite the thinness of the laptop, its connectivity is not left out since there are 2 USB-C ports (3.2 Gen 2, DisplayPort 1.4, allowing charging at 100 W) on the right side, an SD card reader and a mini-jack socket on the left side; on the back, there are 2 USB-A 3.2 Gen 2 ports in addition to the proprietary power connector. Lenovo also includes a small USB-C hub that includes an additional USB-A port, an HDMI port and a VGA port. The latter is no longer really used today; we would have preferred an Ethernet port, much larger for players. Fortunately, the Wi-Fi 6 Killer AX1650 is present for a very fast connection to the network, and the Bluetooth is standard 5.1. Finally, the webcam only films in 720p, but it has the advantage of having a small physical cache to ensure respect for privacy.
To open the chassis, simply remove Phillips screws. An appreciable choice since this format is much more widespread than Torx. Inside, we see that one RAM module is soldered, but the other remains replaceable. Likewise, the M.2 SSD is removable and allows storage to expand.
For a PC gaming, the Legion Slim 7 is relatively quiet compared to other models of its kind. It only reaches “only” 42.9 dB in full swing, but the ventilation is of course clearly audible. The heating is well contained: we noted a maximum of 50.8 ° C at the air outlets, but the center of the keyboard only rises to 40.9 ° C.
The RTX 3060 chosen by Lenovo has a thermal envelope of 100 W, halfway between the lowest TGP on this model (60 W) and the highest (125 W). Coupled with the Ryzen 9, it was able to express itself without any problem and obtained a very good GPU performance index of 136. This is not at the level of the best RTX 3070 and 3080 of course, but it clearly outclasses some low 3070s. TGP.
In practice, we have played most of the latest games at the moment without a problem, although the most demanding titles like Metro Exodus (Enhanced Edition) and Cyberpunk 2077 did not reach the 60 fps which ensures a perfectly smooth gaming experience. It should be noted however that we put all the graphics in ultra and that the DLSS of Nvidia is activated only with the raytracing; there is therefore a good margin of maneuver to increase the fps in the games by deactivating the latter.
The Legion Slim 7 is therefore a good computer for gamers, even if we regret not being able to take full advantage of its 165 Hz screen. To achieve sufficient speed – for competitive multiplayer games in particular – it will therefore be necessary to lower the quality of the graphics. and think about enabling DLSS.
For a computer gaming, the Legion Slim 7 remains very thin (18.9 mm thick) and even light (1.9 kg). Like any 15.6-inch computer, it is on the other hand relatively bulky (35.6 x 25.2 cm), but remains easily transportable in a backpack. Its 230 W charger can be placed on the edge to take up less space on a desk, but it is nonetheless massive: it still weighs 952 g (with cables).
In terms of autonomy, it is doing quite well for a PC intended for gaming. We have exceeded 6 hours in video playback on Netflix via the Chrome browser, headphones plugged in and volume set to 50%. It will be necessary to remember to activate the hybrid mode in the Lenovo Vantage software so that the graphics card is deactivated in office use. Be careful, some games are not compatible with this mode and it is better to stop it before starting a game.
One of the best processors around.
Good performance of the GeForce RTX 3060.
165 Hz screen.
Thin and light chassis for a gaming PC.
Customizable RGB keyboard.
No Ethernet port.
Low contrast and brightness.
720p webcam only.
The Lenovo Legion Slim 7 is an excellent PC that can be used for both gaming than to tackle demanding creative software (video editing, 3D rendering, or photography, for example). This is all made possible by a high-performance AMD Ryzen 9 5900 HX processor and a durable GeForce RTX 3060 graphics card. In game, the PC is also doing well, and it ultimately suffers from few shortcomings, mainly a screen perfectible and the lack of Ethernet port.
