The Alienware leans more towards premium pricing whereas the Legion 5 Pro is slightly less expensive, yet offers double the storage. Battery life on the Legion 5 Pro is short compared to the Alienware, posing a compromise for longer usage away from power sources. Both are strong contenders for demanding tasks like gaming, 3D, and engineering applications due to their powerful CPUs and GPUs. Give Feedback

The Lenovo Legion Pro 5 is very good for gaming and AI, while the Dell Alienware m15 R7 is good.
The Lenovo Legion Pro 5, with its more recent Nvidia RTX 4070 graphics card, offers top-tier performance for gaming and 3D applications, while the Dell Alienware m15 R7, though slightly behind in graphical power with an Nvidia RTX 3070 Ti, compensates with a higher screen refresh rate, which can make for smoother visuals in fast-paced games. When considering screen quality, both have high-resolution IPS displays, but the Legion Pro 5 offers a taller 16:10 aspect ratio for more vertical content display compared to the Alienware's standard 16:9, although the contrast in vivid colors and overall screen brightness is not a primary determinant here.

Brandon Hill | October 2022
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."

Mark Knapp | July 2023
"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."
