Marius Schell | February 2021
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."

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."
