The Lenovo Legion Pro 7i is excellent for gaming and AI, while the Dell Inspiron 15 3525 is only fair.
The Dell Inspiron 15 3525 has less gaming and 3D capabilities due to its integrated Vega 7 GPU and a lower screen refresh rate of 60Hz, while the Lenovo Legion Pro 7i stands out with its high-end Nvidia RTX 4080 graphics card and a much higher refresh rate of 240Hz.

The Lenovo Legion Pro 7i 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 15 3525, with its fair screen quality, offers sufficient resolution and brightness for everyday tasks like browsing and document editing, but may fall short in the precise color representation needed for engineering and lacks the high refresh rates required for smooth gaming and 3D rendering. On the other hand, the Lenovo Legion Pro 7i, with its very good screen quality, provides sharp images and vibrant colors that cater to the detail-oriented nature of engineering work, but similarly does not offer the high refresh rates that games and 3D applications typically benefit from. For those prioritizing work in engineering over gaming, the Lenovo's capacity to display a wide range of colors makes it a better fit, while neither laptop may satisfy the demands of modern gaming experiences.

PCMag
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."

"Passionate gamers who want to play demanding modern titles with maximum details and don't mind spending the moolah will find the Lenovo Legion 7 Pro to be the right choice. The bright, sharp, and color-accurate 16:10 QHD 240 Hz display makes for an immersive viewing experience. The hardware is housed in a stylish chassis that feels premium and scores well in terms of workmanship and stability. Other aspects such as sound quality, input devices, and connectivity also seem to be near-perfect."
