The Dell G15 5520 is pricier but offers better performance for intensive tasks like gaming or 3D rendering due to its higher-end processor and dedicated graphics card. It also has more storage and a high refresh rate screen but is heavier and has a shorter battery life, making it less portable than the Inspiron. In contrast, the Dell Inspiron 16 5620 is more budget-friendly, has a larger screen with a higher resolution, and longer battery life, which might suit everyday usage and productivity tasks better and is lighter for easy carrying.

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."

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."
