The ASUS TUF Gaming F15 offers strong gaming performance and a numeric keypad, making it suitable for general use and gaming, but it is less portable due to its weight and size, and battery life is shorter. On the other hand, the Lenovo Slim Pro 9i is more expensive but provides a sharper, brighter, and higher resolution touch screen, better portability, and longer battery life; it's well-suited for professional and engineering applications as well as general use. Choose the ASUS if you prioritize gaming and cost savings, and the Lenovo if you value screen quality, portability, and battery life for diverse and intensive tasks. Give Feedback

NotebookCheck

Allen Ngo | March 2022
"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."

Matthew S. Smith | August 2023
"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
