The Dell G15 5520 boasts a powerful Nvidia RTX 3060 GPU, making it well-suited for intensive gaming, 3D rendering, machine learning, and engineering tasks. It has a larger screen, but is heavier and has a lower battery life, which may affect portability. On the other hand, the Lenovo ThinkBook 13s offers better battery life and portability with a lighter build and a higher-resolution touchscreen display, making it ideal for general use and premium business needs. However, its integrated graphics mean it's less suited for graphically demanding applications. Choose the Dell for performance-heavy tasks or the Lenovo for on-the-go business and general usage.

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 best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
