The Dell Alienware m17 R5 tends to be a touch less expensive and boasts a larger screen, longer battery life, and higher refresh rate, which is great for gaming and fast-paced visuals. However, it's heavier and larger than the Lenovo Legion 7, making it less portable. On the other hand, the Lenovo Legion 7 offers a higher resolution display, which is sharper and better for creative work or engineering that benefits from extra screen detail. It's also lighter and has a different aspect ratio that may be preferred for productivity tasks. If portability and screen clarity are priorities, consider the Lenovo Legion 7, but if you value gaming performance and a longer battery lifespan, the Dell Alienware m17 R5 could be a better choice.

The Lenovo Legion 7 and Dell Alienware m17 R5 are both very good for engineering and design.
The Dell Alienware m17 R5 and Lenovo Legion 7 are highly regarded for engineering and design due to their robust CPU and ample RAM, which are critical for demanding software, and their high-end GPUs that support intensive graphics tasks. While both have quality displays, the Alienware has a larger screen that's advantageous for detailed work, but the Legion 7's higher resolution and brightness offer superior image clarity, with the tradeoff being that the Alienware is less portable due to its heavier weight and larger size.

How the Dell Alienware m17 R5 and the Lenovo Legion 7 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 Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
