Choosing between the ASUS Zenbook Pro 17 and the Dell Alienware X17 R2 depends on your priorities. If you're seeking better performance for intensive tasks like 3D rendering, machine learning, or playing the latest games, the Alienware, with its high-end graphics card, is the go-to option. However, you'll compromise on battery life and portability, as it's heavier and drains faster. Meanwhile, the Zenbook offers longer battery life and is lighter, making it more portable for general use and suitable for a wider range of tasks, but it won't handle demanding applications as effectively as the Alienware. Additionally, the Zenbook typically costs less, so it's a more budget-friendly choice if top-tier performance isn't critical for you. Give Feedback

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."
