The Lenovo Legion Pro 5 is very good for gaming and AI, while the Dell Inspiron 15 3525 is only fair.
The Lenovo Legion Pro 5 surpasses the Dell Inspiron 15 3525 in gaming and 3D applications primarily because of its significantly more powerful Nvidia RTX 4070 GPU and a higher screen refresh rate, enhancing visual fluidity and detail. While the Dell model houses an integrated AMD graphics and standard screen refresh rate sufficient for casual gaming, the Lenovo's superior graphics processing capability and faster refresh rate make it ideal for more demanding gaming and 3D tasks.

The Lenovo Legion Pro 5 has a better screen than the Dell Inspiron 15 3525 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron's screen offers sufficient clarity and brightness for everyday tasks and productivity software used in general use and engineering, but its limited color range and lower refresh rate reduce its effectiveness for color-critical engineering work and make it unsuitable for the fast-paced visuals required in gaming and 3D applications. The Lenovo Legion Pro, with a higher quality display, provides vibrant colors and better viewing angles which benefit both general use and professional engineering design work, where color accuracy is crucial; however, its poor refresh rate falls short for gaming and 3D work where smooth motion rendering is essential. Both laptops are less ideal for gaming and 3D pursuits due to their screen refresh limitations, prioritizing resolution and color over speed, which might hinder fast-paced visual experiences.

Mark Knapp | January 2023
"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. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."

"It doesn't quite match its Legion Pro 7i sibling as an Editors' Choice winner, but Lenovo's AMD-powered Legion Pro 5 Gen 8 is a stylish, well-built gaming laptop with solid performance at both 1080p and its sharper native resolution. It's cheaper than some comparably equipped machines and better than some similarly priced ones. That's a recipe for success, even without its frequent availability of discounts or sales. A brighter screen and longer battery life would be nice, but even as is the Legion Pro 5 earns a solid recommendation."
