The ASUS ROG Flow X13 offers better performance with a higher-end processor and graphics card, making it suitable for intensive engineering tasks, gaming, and machine learning. It's more portable due to its smaller screen and lower weight, plus it has a touchscreen and higher display resolution. However, it comes at a premium price. On the other hand, the Lenovo Legion Slim 5, while less expensive, has less storage, a larger and heavier build without a touchscreen, and a lower display resolution. It still delivers solid performance for general use and gaming but may not be as well-suited for highly demanding tasks. Both laptops support hardware ray tracing and DLSS for advanced image rendering, but if budget constraints are a concern, the Lenovo offers a good balance between cost and capabilities. Give Feedback

How the ASUS ROG Flow X13 and the Lenovo Legion Slim 5 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."
"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."
