When considering the ASUS ROG Strix and the Lenovo IdeaPad Slim, prioritize your needs: if you require top-level performance for gaming or demanding tasks, the ASUS is designed for that; however, it’s usually heavier and has a shorter battery life, which is less ideal for on-the-go usage. The Lenovo, more affordable and lightweight, offers sufficient performance for everyday tasks and longer battery life, making it more convenient for travel and routine work. Choose ASUS for high-end use at a higher cost and lower portability, or Lenovo for general use, cost savings, and better mobility. Give Feedback

The ASUS ROG Strix G18 (2024) is very good for gaming and AI, while the Lenovo IdeaPad Slim 5i is only fair.
The ASUS ROG Strix G18 is equipped with a dedicated high-performance GPU and a high screen refresh rate, making it suitable for immersive gaming and smooth 3D rendering; however, the Lenovo IdeaPad Slim 5i, with a less powerful GPU and lower refresh rate, offers adequate performance for more casual gaming and basic 3D tasks while also providing a balance between cost and functionality for everyday use. Both laptops include capable CPUs and good screen quality, but it's the GPU and screen refresh rate that most significantly influence their gaming and 3D capabilities.

The ASUS ROG Strix G18 has a better screen than the Lenovo IdeaPad Slim 5i for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18 boasts a high-resolution display with excellent brightness and panel type, providing sharp, vibrant visuals that make it ideal for both general use and detail-oriented work in engineering and design, where color accuracy is key. However, its lower refresh rate could hinder the smoothness needed for immersive gaming and 3D applications, where swiftly changing images benefit from higher refresh rates. Meanwhile, the Lenovo IdeaPad Slim 5i provides satisfactory display features for everyday tasks and professional design work, but it doesn't excel in any particular area, making it less suitable for high-end gaming and 3D rendering where standout screen performance is crucial.

"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."
"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
