When choosing between the Dell Alienware m16 R2 and the Lenovo Legion 5 17", consider that the Alienware often offers superior gaming performance and higher-end features, making it well-suited for demanding games and software, but this comes with a higher price tag and potentially shorter battery life. The Legion 5, on the other hand, provides a larger screen and may offer better value for money, with competent gaming performance and a balance between cost and capability, which could be more appealing for general use and less resource-intensive gaming.

LaptopMag

Momo Tabari | January 2024
"Alienware’s m16 R2 is a solid gaming laptop that leaves much to be desired, particularly in its quest to fulfill your needs as a product for productivity. Battery life under eight hours and a dim display are both vital issues for something that will accompany you through school projects or a workday. However, the Alienware m16 R2 is an exceedingly powerful gaming laptop, consistently being one of the best in our performance tests when compared against similar products. Even then, its display is lacking color, its fans get pretty darn loud, and its speakers aren’t punchy enough to rise above that noise."

Sebastian Bade | February 2022
"The Lenovo Legion 5 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."
