For better performance in engineering tasks with higher screen resolution, the Lenovo ThinkPad P16 excels, but it's heavier and less portable. The Dell G15 5520, on the other hand, offers strong gaming capabilities and a higher refresh rate screen, at a lower price and weight, making it more portable, but compromises on screen resolution and engineering precision offered by the ThinkPad. If long battery life is essential, the ThinkPad P16 outperforms the Dell G15 5520. If cost is a concern and gaming is a priority, the Dell may be a more suitable choice, however, for demanding engineering applications and premium features, the ThinkPad may be worth the extra investment.

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."

Eric Grevstad | February 2023
"It's only a few months since we gave the MSI CreatorPro X17 one of our rare 4.5-star ratings and our top mobile workstation honor, but the Lenovo ThinkPad P16 Gen 1 matches that achievement in a more premium overall build. Ultimately, its build quality, screen, and keyboard give our latest Editors' Choice nod to the Lenovo—it's enough of a monster on almost all fronts that it simply cannot be ignored."
