The Dell Alienware m17 R5 is a robust choice for gaming with a larger screen and slightly better battery life, but heavier, which affects its portability. The Lenovo Legion 5i Pro offers a higher screen resolution that could enhance your experience for tasks like photo editing or watching high-definition content, along with a newer processor that may give it an edge in performance, but has less storage out of the box and a shorter battery life. Both are equipped with powerful graphics cards suited for gaming and demanding tasks, so consider your priorities, like screen size and resolution, weight, and battery life when making your decision.

The Dell Alienware m17 R5 has a better screen than the Lenovo Legion Pro 5i for gaming and AI, while the Lenovo Legion Pro 5i has a better screen for general use, and engineering and design.
For general use, the Dell Alienware m17 R5's balance of resolution and brightness offers a clear and vivid display, but for gaming and 3D applications, its lower refresh rate can hinder smooth motion rendering. The Lenovo Legion Pro 5i, with a similarly bright and high-resolution display, excels for general use and engineering tasks due to its wide color gamut coverage, enhancing color accuracy and detail. Yet for gaming and 3D, despite its great color representation and clarity, like the Alienware, it falls short on providing the optimal fluid visuals that a high refresh rate panel would deliver.

How the Dell Alienware m17 R5 and the Lenovo Legion Pro 5i compare to other laptops
"Overall, the all-AMD system in the Alienware m17 R5 is impressive, especially the graphics performance. However, various driver issues and unnecessary inconsistencies prevent us from truly enjoying such a potent gaming machine. In addition to strong 3D performance, we particularly like the build quality, the fairly bright UHD display with high color space coverage, and the fact that the gamer is often quiet when not under load and also rather quieter than some competitors under load."
"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
