If performance matters most, especially for 3D, machine learning, or engineering tasks, the MSI Stealth GS66 has a high-end graphics card and processor that outshine the Asus Vivobook S 15. However, the Asus offers better battery life and comes at a lower price, making it more suitable for general use. The Asus is lighter but the MSI has a sturdier build and better heat management, which can be important if you plan to carry your laptop often or use it for long periods. The MSI's keyboard and display are also superior, although it is less portable due to its weight and larger power brick. If gaming is a priority, the MSI Stealth GS66's advanced graphics make it a clear choice, despite its higher cost and shorter battery life. Give Feedback

"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."

"The MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
