The Dell G15 5520 is good for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The Dell G15 5520 outperforms the ASUS Zenbook Duo 14 in gaming and 3D tasks primarily due to its superior GPU and higher screen refresh rate, which are very important for smooth and visually detailed gaming experiences. While the Zenbook Duo may have decent capabilities, its hardware is not as gaming-focused as the G15, which offers a more powerful GPU setup and a display that supports faster on-screen action.

The Dell G15 5520 is very good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The Dell G15 5520 is rated higher for engineering and design use thanks to its more powerful Intel i7-12700H processor, higher RAM, and stronger Nvidia RTX 3060 GPU, which are crucial for such tasks, whereas the ASUS Zenbook Duo 14's lesser RAM and integrated Intel Iris Xe graphics may not handle intensive tasks as efficiently. Additionally, the Dell has a larger screen and faster refresh rate which benefits detail-oriented work, although its heavier weight and larger size reduce portability compared to the lighter and more compact ASUS.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."
