Olivier Martin, Ryan Lim, and John Peroramas | April 2023
"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."

"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."
