For a balance of performance and portability with a touch of gaming prowess, the Dell Alienware X17 R2 is a solid choice, offering a high-performance CPU and GPU, ample RAM, and a large screen with a fast refresh rate, though it's heavier and less portable. On the other hand, the Lenovo Yoga Pro 9i, with its sleek design, high-resolution touchscreen, and versatile use for both work and entertainment, is more portable and has a better battery life, making it ideal for general use and productivity on the go, but it may not handle intensive gaming or engineering tasks as well as the Alienware.

NotebookCheck
Allen Ngo | May 2022
"The Alienware x17 R2 recognizes targets a significantly higher TGP of 175 W for a roughly 30 percent performance boost over laptops running on the ~100 W GeForce RTX 3080 Ti like the Razer Blade 15 or Gigabyte Aero YE5. Similar results can be found through the CPU as well. This single aspect of the Alienware is perhaps the biggest differentiating factor between it and other ultrathin gaming laptops. Of course, the "performance at all cost" approach comes with drawbacks. Power consumption in particular is through the roof and battery life suffers because of it even when on the lowest performance settings."
