For better performance in tasks like 3D rendering, machine learning, or gaming, the ASUS TUF Dash 15 with its RTX 3060 graphics card is a strong option, while the Lenovo IdeaPad Slim 7i, with its integrated graphics, is more suited for general use. The ASUS model is heavier and thicker, so it's less portable than the Lenovo, which is lighter and slim. Battery life of the Lenovo is also superior, making it a better choice if you need to work on the go without frequent access to a power outlet. However, if your activities demand high-performance graphics, the additional cost of the ASUS could be justified. Give Feedback

How the ASUS TUF Dash 15 and the Lenovo IdeaPad Slim 7i compare to other laptops
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
