The ASUS ZenBook Pro Duo 15, with its OLED screen and 4K resolution, excels in vibrant screen colors and is suitable for tasks that benefit from dual screens, like creative work or multitasking. On the other hand, the Dell Alienware X17 R2, sporting a faster refresh rate display and more powerful graphics card, is tailored for intensive gaming and can also handle demanding engineering applications. Both have similar battery life, but for portability, the ASUS is lighter but has a smaller screen, whereas the Alienware is heavier with a larger display. If price is a concern, the ASUS is a little less expensive, but if gaming or engineering performance is a priority, the Alienware edges ahead despite the additional cost. Give Feedback

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
