If you prioritize gaming or intensive tasks, the Dell laptop may suit you as it often has more powerful hardware for those needs, but it’s also heavier, which affects its portability. The Lenovo, on the other hand, is typically more expensive but offers a lighter, more portable design, making it better for on-the-go use and general tasks. The longer battery life of the Lenovo is beneficial for extended use without charging, but if you need to save money and require more computing power, the Dell might be a better fit despite its bulkier build and typically shorter battery life.

The Dell G15 5520 is good for gaming and AI, while the Lenovo ThinkBook 13x is only fair.
The Dell G15 5520 packs a more powerful GPU and higher screen refresh rate, making it well-suited for gaming and 3D applications where smooth visuals and graphics performance are key. While the Lenovo ThinkBook 13x offers decent performance for lighter tasks, its GPU and screen refresh rate are not as robust, so it won't handle demanding games and 3D work as effectively.

The Dell G15 5520 has a display that offers crisp images and vivid colors due to its panel type and resolution, making it good for general use and detailed engineering work, but it lacks a high refresh rate, which is crucial for smooth visuals in gaming and 3D applications.

Rtings
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."
