Florian Glaser | October 2022
"The Lenovo IdeaPad Gaming 3 is one of the most powerful RTX 3050 Ti laptops. If you disregard the mediocre quality of the case in terms of the material and workmanship, Lenovo has created a successful budget gaming laptop with the IdeaPad Gaming. Thanks to high TDPs and constant performance development, the Core i5-12500H and GeForce RTX 3050 Ti are able to show their full power, while in contrast, the (mostly slower) competitors deliver a better battery life. However, hardly any of the alternative laptops are able to reach the image quality of the Gaming 3. Most of the competitors are left behind in terms of the color space and brightness."

"The MSI Katana 15 B12 combines a Gen12 CPU with an RTX 4050, which is actually not a bad idea for a budget gamer. The CPU is anything but bad and the GPU in the Katana 15 proves to be significantly more efficient than last year's models. However, our main point of criticism for budget gamers is the price: while you can get budget laptops with RTX 3060 from around US$800, you pay a whole US$1,499.99 here! The efficiency advantages of the RTX 4050 do not justify this price premium."
