If you prioritize gaming or tasks that require powerful graphics like 3D modeling, the ASUS TUF Gaming F15, with its superior dedicated GPU and high refresh screen, offers better performance. However, it's heavier and has a shorter battery life. Conversely, the Lenovo IdeaPad Slim 7i is more portable, has a longer battery life, and a higher-quality webcam and speakers, but it's not suited for intensive gaming or heavy graphics tasks due to its integrated graphics. The Lenovo may be more affordable and sufficient for general use, while the ASUS is better for engineering and graphically intensive tasks at a higher price point. Give Feedback

The ASUS TUF Gaming F15 is very good for engineering and design, while the Lenovo IdeaPad Slim 7i is good.
The ASUS TUF Gaming F15 stands out for engineering and design due to its robust CPU and GPU, which are crucial for compute-intensive tasks like 3D rendering and simulations; but it's heavier, affecting its portability. The Lenovo IdeaPad Slim 7i, while also providing good CPU performance and ample RAM for multitasking, has a less powerful integrated graphics solution and a lighter build, which favors portability but may not handle graphic-intensive engineering software as effectively.

The ASUS TUF Gaming F15 has a better screen than the Lenovo IdeaPad Slim 7i for gaming and AI, while the Lenovo IdeaPad Slim 7i has a better screen for engineering and design, and content creation.
For general use, both the ASUS TUF Gaming F15 and Lenovo IdeaPad Slim 7i have screens with resolution and brightness that meet everyday needs, but the TUF's gaming-oriented design doesn't significantly enhance general viewing experiences. Engineering and design work benefit from the Lenovo's superior color accuracy and wider color gamut, making it more suitable for professionals who rely on precise color representation. When it comes to gaming and 3D applications, the ASUS falls short due to its lower refresh rate, which is less conducive to the smooth visuals that these tasks demand, despite its gaming branding.

How the ASUS TUF Gaming F15 and the Lenovo IdeaPad Slim 7i compare to other laptops
"Aside from all the chassis updates, the new TUF Gaming is most notable for its much higher TGP target of 140 W compared to only 95 W on the previous generation. PC makers everywhere are using the same GeForce GPUs this year since Nvidia has yet to launch the successor to the mobile RTX 3000 series. The more demanding processors of the new TUF Gaming has directly impacted battery life and the size of the AC adapter. Don't expect runtimes to be longer than on the previous generation under most conditions and be prepared to carry around an even larger AC adapter than before."
"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."
