The Lenovo Legion Pro 5 is very good for gaming and AI, while the Dell Inspiron 15 3511 is only fair.
The Lenovo Legion Pro 5 is very good for gaming and 3D because it has a high-performance Nvidia RTX 4070 GPU and a screen with a high refresh rate of 165, which enhances smooth visuals in fast-paced games. In contrast, the Dell Inspiron 15 3511 is considered fair for these tasks as it comes with the less powerful Intel Iris Xe graphics and a lower 60 refresh rate screen, which means it won't handle visually intensive tasks or fast gaming as well.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"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."
