The ASUS Vivobook S 15 offers a lower midrange price with a larger storage capacity of 1TB, 16GB of RAM, and an AMD Ryzen 7 processor with integrated Vega 8 graphics, making it suitable for general use and some light engineering tasks. Its 15.6-inch IPS display with a resolution of 1920 x 1080 is good for everyday tasks, though it lacks touchscreen capabilities. The laptop is relatively portable with a decent battery life, but it's not designed for intensive gaming or advanced 3D rendering and machine learning tasks. It has a good selection of ports, including USB-C and HDMI, and offers a backlit keyboard and fingerprint reader for security. On the other hand, the Lenovo Yoga Pro 9i is priced in the midrange segment and comes with a more powerful Nvidia RTX 4050 dedicated GPU, which significantly enhances performance for gaming, 3D rendering, and machine learning tasks. Its 16-inch Mini LED display with a higher resolution of 3200 x 2000 and touchscreen capability provides vibrant colors and sharp images, ideal for creative professionals and those who appreciate high-quality visuals. The Yoga Pro 9i also boasts superior build quality, a premium backlit keyboard, and advanced security features like facial recognition. It has a good selection of ports, including Thunderbolt 4, and supports fast charging via USB-C. The laptop's performance is top-notch for general use, gaming, and engineering tasks, with excellent scores across the board. However, it is more expensive, has less storage at 512GB, and is slightly heavier, which may impact its portability compared to the ASUS. In summary, if you prioritize a balance of performance and price for general use and are okay with a non-touchscreen display, the ASUS Vivobook S 15 is a solid choice. However, if you're willing to invest in a laptop with superior display quality, dedicated graphics for gaming and creative work, and don't mind the higher price and slightly reduced portability, the Lenovo Yoga Pro 9i is the better option.

Mario Petzold | February 2023
"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."
