For better performance in 3D rendering, machine learning, and gaming, the Dell G15 is a stronger choice due to its high-end Nvidia RTX 3060 graphics card. However, it is heavier and thicker, making it less portable than the ASUS Vivobook S 15 OLED. The ASUS offers excellent color accuracy and higher screen brightness with its OLED display, making it suitable for general use and work that requires color precision. While both have the same amount of storage and RAM, the ASUS has a more recent processor, but for intensive tasks like gaming, the GPU in the Dell will be more significant. The ASUS also has a slight edge in battery life and portability, but if gaming and graphics work are your priority, the Dell could provide better performance. Both laptops are similarly priced, so your decision should be guided by your specific use-case priorities. Give Feedback

The Dell G15 5520 is good for gaming and AI, while the ASUS Vivobook S 15 OLED is only fair.
The ASUS Vivobook S 15 OLED is strong for gaming and 3D given its high screen refresh rate and quality OLED display, although its integrated GPU may limit performance in the most demanding games and applications. In contrast, the Dell G15 5520 has a dedicated Nvidia RTX GPU that's superior for such tasks and a high screen refresh rate, but it has a less impressive screen quality compared to the OLED panel on the Asus.

The ASUS Vivobook S 15 OLED has a better screen than the Dell G15 5520 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS Vivobook S 15 OLED boasts an OLED display which means vibrant colors and deep blacks, contributing to its high-quality visuals for both general use and tasks like engineering and design that rely on color accuracy. However, the low refresh rate typical of OLED screens makes it less ideal for gaming and 3D applications, where a high refresh rate is crucial for smooth visuals. Conversely, the Dell G15 may have a good enough resolution and brightness for everyday tasks and sufficient color reproduction for engineering, but similarly falls short for gaming and 3D due to an average refresh rate.

"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."

"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."
