The ASUS ROG Flow X13 is the more expensive option with higher performance suited for intensive engineering tasks, 3D rendering, machine learning and gaming due to its superior graphics card and processor. It also has a higher refresh rate display which is beneficial for fast motion activities like gaming. However, it is smaller and lighter, which makes it more portable. On the other hand, the ASUS Vivobook S 15 is less expensive with adequate performance for general use and everyday tasks, but has a larger screen size. Its gaming and engineering capabilities are more limited compared to the Flow X13 because of its integrated graphics. The Vivobook offers a slightly longer battery life and is also heavier, which may affect portability. Both laptops have similar storage and RAM, making them capable for a range of tasks. Choose the ROG Flow X13 if you prioritize performance and portability for demanding activities, or the Vivobook S 15 if you prefer a larger screen and affordability with sufficient capabilities for general use.

The ASUS ROG Flow X13 has a better screen than the ASUS Vivobook S 15 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 offers superior resolution, brightness, and panel technology, making it well-suited for crisp and clear viewing in general use environments, while its wider color gamuts cater well to professionals in engineering and design, who need accurate color representation. However, its lower refresh rate makes it less ideal for gaming and 3D applications, where smoother motion is a priority for an immersive experience. In contrast, the ASUS Vivobook S 15, while adequate for everyday tasks and some design work with its fair screen characteristics, falls short in providing the high color fidelity and refresh rate needed for cutting-edge design work or fluid gaming visuals.

How the ASUS ROG Flow X13 and the ASUS Vivobook S 15 compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"Internals make Asus VivoBook S15 laptop a compelling option. The Asus multimedia laptop may look rather below-average with its modest black chassis, lack of a dedicated GPU, limited RAM and meagre port selection without Thunderbolt support. But your impression of the device will start changing once you set your eyes on its high-contrast OLED capable of producing deep blacks and highly accurate colours. And your opinion will change completely when the VivoBook is switched on. The AMD CPU can effortlessly keep up with powerful rivals from Intel. The integrated Radeon graphics blows away Intel's iGPU when it comes to graphics workloads such as rendering and simpler games."
