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.

The Lenovo ThinkPad P16 has a better screen than the Dell G15 5520 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell G15 5520, with its decent resolution and brightness, provides a pleasant visual experience for every day tasks and detailed work in engineering or design, but lacks the high refresh rate desired for smooth 3D gaming. The Lenovo ThinkPad P16 steps up with better resolution and brightness, enhancing usability for general computing and precision in design, and offers wider color gamut coverage which is essential for professional-grade color work. However, despite these strengths, both laptops fall short for gaming and 3D applications due to their lower refresh rates, which can't deliver the fluid motion graphics that these activities typically require.

The Lenovo ThinkPad P16 and Dell G15 5520 are both very good for engineering and design.
The Dell G15 5520 offers a robust i7 processor and an RTX 3060 GPU, which are excellent for engineering software and possibly some design work, though its lower screen resolution and color coverage might limit the quality of visual work compared to the Lenovo ThinkPad P16, which has a higher-resolution display and superior color accuracy with an RTX A1000 GPU well-suited for professional design tasks. While both have high-quality keyboards and sufficient RAM for multitasking, the ThinkPad P16 is slightly less portable due to its greater weight but compensates with a significantly longer battery life, making it a more versatile device for extended work sessions away from power outlets.

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."

"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."
