The Dell G15 5520 is well-suited for intensive gaming and engineering tasks due to its powerful processor and dedicated graphics card, but it comes at a higher price and is heavier, making it less portable. The Dell Inspiron 15 3520, on the other hand, is more budget-friendly and lighter, therefore more portable, but less equipped for demanding applications with its less powerful processor and integrated graphics. Both have similar screen sizes and resolutions, but the G15 has a higher refresh rate which is better for fast-moving visuals. Consider the G15 if performance is a priority and the Inspiron if you need a more cost-effective and portable option. Give Feedback

The Dell G15 5520 is good for general use, while the Dell Inspiron 15 3520 is only fair.
The Dell G15 5520 is favored for general use due to its more powerful Intel i7 processor and double the RAM of the Dell Inspiron 15 3520, which is equipped with an Intel i3 processor and less RAM, impacting multitasking and overall performance. While both have similar screen sizes and types, the G15's superior CPU, GPU, and larger battery contribute to its enhanced capability, but it's less portable and heavier than the Inspiron, which offers better portability, a slightly better portability score, and excellent heat management.

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."

"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."
