How the ASUS Vivobook S 15 and the Lenovo Legion Slim 5 compare to other laptops
"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 Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
