The ASUS ROG Strix G15 Advantage Edition offers a robust AMD processor and GPU combination, which is great for gaming and other graphics-intensive tasks, but it is heavier and has a larger form factor, affecting portability. On the other hand, the Lenovo Slim Pro 9i has a high-resolution mini LED touchscreen display making it well-suited for design and media professionals who prioritize screen quality and a more portable design, but its graphics might not be as powerful as the ASUS for high-end gaming. Both laptops are similarly priced, so your choice will largely depend on whether you prioritize gaming and intensive tasks or portability and screen quality for professional use. Give Feedback

The Lenovo Slim Pro 9i has a better screen than the ASUS ROG Strix G15 Advantage Edition for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Slim Pro 9i stands out with a high-resolution display and impressive brightness, offering crisp visuals and clarity, while the ROG Strix's decent resolution and brightness provide a good experience but not the best. In engineering and design, the Slim Pro's superior color coverage with high DCI-P3 and Adobe RGB ensures accurate color representation, essential for professional work, whereas the ROG Strix provides adequate but not top-tier color accuracy. However, for 3D and gaming, the ROG Strix's display falls short due to lower refresh rates compared to other gaming-centric laptops, just as the Slim Pro 9i doesn't cater to the high refresh rates desired for smooth gameplay and 3D rendering.

"The Asus ROG Strix G15, as the first in a line of "AMD Advantage"-branded notebooks, is a statement that yes, you can get a premium AMD gaming notebook. Maybe you can't have it all, but you can get pretty close. The ROG Strix G15's combination of the AMD Ryzen 5900HX and Radeon RX 6800M, as well as other technologies that take advantage of them, make a potent, thin gaming machine. Powerful Dolby Atmos speakers and long battery life when you aren't gaming are nice bonuses."

"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."
