When choosing between the ASUS ZenBook Pro Duo 15 and the Dell Inspiron 14 5425, the main considerations are price, performance, portability, and battery life. The ASUS is on the higher end with powerful components suitable for intensive tasks like 3D rendering, machine learning, or engineering work, but it is heavier and has a shorter battery life, making it less portable. The Dell, on the other hand, is cheaper, lighter, and has a longer battery life, making it more portable and ideal for general use, but it may not handle demanding applications as smoothly as the ASUS. The ASUS also features a high-quality OLED touchscreen while the Dell has a standard IPS screen. If portability and price are your priorities, and your work doesn't demand top-tier performance, the Dell Inspiron might be the better choice. However, if you need a laptop for high-performance tasks and can handle a premium price and less portability, the ASUS ZenBook Pro Duo could be the way to go. 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."

"A slim chassis, an acceptable weight (1.6 kg) and a real-world battery life of almost 13 hours turn the Inspiron into a mobile companion. Good: The battery can not only be charged using Dell's proprietary power adapter, but also with a universal USB-C power adapter (min. 45 watts). Office and Internet applications are handled by the built-in combination of Ryzen 5 5625U APU and 16 GB of RAM just as easily as modest computer games. Heat and noise development are generally okay, but the laptop should work a bit quieter under full load."
