Andreas Osthoff | September 2021
"The Lenovo Legion 5 15 is an affordable gaming laptop with a lot of power. The new AMD processor Ryzen 7 5800H offers plenty of performance and it is also very efficient. The combination with the fast 130W version of the GeForce RTX 3060 ensures high gaming performance. We also like the fast 165 Hz display with the 1080p resolution. The automatic graphics switching causes some problems with stutters, which are very annoying. If you do not need long battery runtimes, you should definitely deactivate the hybrid graphics mode in Lenovo's Vantage app. The Legion 5 15 is never silent."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
