If you prioritize advanced graphics and processing capabilities for tasks like 3D modeling, machine learning, or gaming, the ASUS ZenBook Pro Duo 15 stands out, especially with its dual displays that benefit multitasking. This makes it suitable for professional creative work and intensive engineering software. It also has a higher build quality and superior speakers. However, it is heavier, less portable, and more expensive. On the other hand, the Dell Inspiron 16 5620 is more affordable and offers longer battery life while being lighter, making it more portable and better for general use. It's a good choice for typical productivity tasks and has a fanless design for silent operation, but it isn't designed for intensive gaming or demanding engineering work. Give Feedback

The ASUS ZenBook Pro Duo 15 is good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The ASUS ZenBook Pro Duo 15 outshines the Dell Inspiron 16 5620 for gaming and 3D applications chiefly due to its superior Nvidia RTX 3070 Ti graphics card and OLED screen, which offer advanced capabilities like hardware ray tracing and exceptional screen quality. In contrast, the Dell employs an Intel Iris Xe GPU and IPS display that, while suitable for everyday tasks, don't match the graphical performance or richness of display necessary for the most intensive gaming and 3D work.

The ASUS Zenbook Pro Duo 15 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro Duo 15 offers high resolution and brightness, along with an exceptional panel type, providing crisp and vibrant visuals for general use and detailed graphics for engineering tasks; however, its refresh rate is low, making it less ideal for 3D applications and gaming where smooth motion is key. The Dell Inspiron 16 5620 delivers fair screen quality with decent resolution and acceptable brightness, which is adequate for everyday tasks and some engineering work, but its color gamut may not be wide enough for precision design tasks and its lower refresh rate limits its effectiveness for gaming and 3D content. Overall, the ASUS stands out for high-end professional work due to its superior screen, while the Dell provides a balanced option for more casual use, with limitations in high-end creative tasks and gaming.

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."

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."
