Lenovo Yoga Slim 7 Pro review: an excellent 14-inch Oled PC with AMD Ryzen 7 5800H

As on the Yoga Slim 7, the Pro version is very well finished. Its anodized aluminum frame feels solid and the screen’s 16:10 aspect ratio offers more display height than the classic 16: 9, handy for many applications. In addition, the borders are very thin, which is always appreciable.

The touchpad is fluid, responsive, and doesn’t sink too far under pressure. The keyboard is also successful. Typing is responsive and rather quiet. The backlight can be set to 4 levels, including an automatic which adapts to the ambient light. There are some interesting shortcuts at the level of the function keys (F1 to F12), in particular to mute the microphone, take screenshots or manage different desktops.

The PC does not have a fingerprint reader, but is equipped with a webcam (720p) with infrared module that allows rapid unlocking with Windows Hello. For connectivity, Lenovo has reduced the possibilities by removing a USB-A port, the HDMI port and the microSD card reader. Strange for a “Pro” model … but there is still a USB-A port, two DisplayPort compatible USB-C ports and of course a mini-jack. Wi-Fi 6 and Bluetooth 5.1 are present for high transfer rates.

The cooling system has proven to be very efficient. We noted around 38 ° C in the center of the keyboard and just over 47 ° C at the air vent. This good temperature management is accompanied by a sound level of 38.8 dB in full action on a game, which is classic on this type of computer. The noise of the fans is therefore audible, but remains bearable.

By removing the 7 Torx screws and dismantling the chassis, we discover a removable M.2 SSD, but unfortunately no accessible RAM module, this one being soldered to the motherboard.

Our model is equipped with a muscular configuration with a 1 TB SSD, 16 GB of RAM, but above all an AMD Ryzen 5800H processor clocked at 3.2 GHz with turbo at 4.4 GHz which has largely proven its worth, since it is one of the best performing chips we have tested today. We normally find the H series in thicker PCs, often those dedicated to gaming and this Yoga Slim 7 Pro is an exception.

So that the heating is not excessive, the manufacturer has limited the TDP of this Ryzen 7 5800H to 45 W. Its maximum frequencies are therefore slightly restricted and it is not as efficient as those of models gaming as the Lenovo Legion 5 Pro where the Dell G15 5515, but still slightly superior to the Ryzen 7 5800U normally found in ultraportables.

Either way, the Yoga Slim 7 Pro can tackle any task without batting an eyelid, from office automation to heavy video processing applications to photography. In game, the PC does well with 38 fps on average on Diablo III (graphics pushed to the maximum) and 58 fps on Overwatch (low quality). What to enjoy without problem a few games that are not too demanding.

The Oled screen is a flagship element of this PC. With a definition of 2880 x 1800 px and a 16:10 format, it has serious arguments. It is also refreshed at 90 Hz, a very rare rate on PCs, located halfway between the classic 60 Hz and 120 Hz that we find more on the slabs. gaming. The display therefore appears slightly smoother when scrolling a page, for example, which improves reading comfort.

The results of our measurements are quite good: color temperature of 6630 K (close to the video standard, 6500 K), maximum brightness of 391 cd / m², and of course infinite contrast ratio and zero afterglow thanks to Oled. However, the screen sins on two characteristics: the colors are not the most precise (Delta E of 4.2) and, as often with Oled panels, the average reflectance is enormous (50%). In practice, its brightness compensates for reflections in most situations, but you must be careful of light sources facing the computer.

Finally, its fine borders provide a very good screen occupancy rate (82%).

With 1.4 kg on the scale, the Yoga Slim 7 Pro is not the lightest of ultrabooks, but it remains compact (312 x 221 x 15 mm). Its charger has been designed to stand upright and therefore takes up less space on a desk. It is not, however, as small as the block-shaped models.

During our video playback battery life test on Netflix, keyboard backlighting off, brightness set to 200 cd / m², headphones plugged in and volume at 50%, the PC lasted 7 h 32 min. A good score in absolute terms, but below what many ultraportables offer. The high definition of the panel is undoubtedly responsible for this limit, computers equipped with conventional Full HD (1080p) screens being advantaged on this precise point.
