The ASUS TUF Gaming F15 offers a robust battery and is tailored for gaming but has a lower screen resolution compared to the Lenovo Legion Slim 5i. The Legion Slim 5i has a higher resolution and aspect ratio, which makes for a better display experience and more vertical screen space, and provides longer battery life for general use. Both laptops feature similar storage capacity and memory, but if a sharper display and longer battery life are your priorities, the Legion may suit you better. However, if you prioritize gaming performance and can compromise on screen detail, the ASUS could be more suited to your needs. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the ASUS TUF Gaming F15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS TUF Gaming F15 has a screen that provides a decent balance of resolution and brightness, making it satisfactory for general tasks, but its limited color range and lower refresh rate aren't ideal for precision in engineering nor the smooth visuals desired in gaming and 3D applications. Meanwhile, the Lenovo Legion Slim 5i offers enhanced color accuracy essential for engineering and design work, coupled with higher resolution and brightness, beneficial for general use, although its lower refresh rate hampers gaming and 3D performance. For gaming and 3D, a laptop with a high refresh rate, which neither of these models excel in, is crucial for fluid motion and responsiveness.

"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."

"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."
