If performance for tasks like gaming, 3D rendering, or machine learning is a priority and the higher cost is not an issue, the Dell Alienware m17 R5 is better equipped with powerful components and a larger display suited for demanding uses. However, it is less portable due to greater weight and size. On the other hand, the Dell Inspiron 15 3511, being more affordable and lightweight, is more suitable for everyday tasks and easier to carry around, but it lacks the high-end graphics and processing capabilities of the Alienware, making it less suitable for intensive tasks.

Christian Hintze | January 2023
"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."

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."
