The ASUS ZenBook Pro Duo 15 offers superior performance for 3D rendering, machine learning, and engineering tasks thanks to its high-end processor and powerful GPU. It's also well-suited for gaming with its OLED screen that displays vibrant colors. However, it's heavier, thicker, and has a shorter battery life, making it less portable. The Dell XPS 15, on the other hand, is lighter, thinner, and offers longer battery life, enhancing its portability. It's less expensive than the ASUS but also has less powerful hardware, making it more suitable for general use rather than intensive tasks. Both devices have high-quality keyboards and displays, though the ASUS has a unique dual-screen setup which may be beneficial for multitasking. 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 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."
