For intensive tasks such as gaming or engineering, the ASUS ROG Strix G18 with its high-performance components like the advanced Intel processor and Nvidia graphics card would excel, but it is heavier and less portable. If you value portability and your tasks are less demanding, such as general use and light productivity, the Lenovo IdeaPad Slim 7i is more budget-friendly, lighter, and has a longer battery life, but it won't handle heavy workloads as effectively as the ASUS. Hence, the choice depends on whether you prioritize performance for demanding applications or portability and cost for everyday use. Give Feedback

The ASUS ROG Strix G18 is very good for general use, while the Lenovo IdeaPad Slim 7i is good.
The ASUS ROG Strix G18 is very good for general use because it has a top-tier CPU and GPU, a high-quality screen, and robust speakers, though it's less portable and has shorter battery life. The Lenovo IdeaPad Slim 7i, while still good for general use with a competent CPU and high screen quality, offers better portability and longer battery life at the cost of lesser storage and no dedicated GPU, which affects performance in visually intensive tasks.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo IdeaPad Slim 7i is only fair.
The ASUS ROG Strix G18 is better for gaming and 3D tasks due to its more powerful Nvidia RTX 4070 graphics card and a higher screen refresh rate of 240, which provides smoother visuals during fast-paced scenes. In contrast, the Lenovo IdeaPad Slim 7i, while still capable, has less graphical power with its Intel Iris Xe graphics and a standard refresh rate of 60, which is adequate for general use but less ideal for intensive gaming and 3D applications.

The ASUS ROG Strix G18 is very good for engineering and design, while the Lenovo IdeaPad Slim 7i is good.
The ASUS ROG Strix G18 excels in engineering and design use with its powerful Intel i9 processor, high-end RTX GPU, substantial RAM, and a high-quality larger screen, making it ideal for demanding tasks despite being less portable. The Lenovo IdeaPad Slim 7i, while still suitable for engineering and design due to its competent i7 processor and integrated graphics, favors portability and better keyboard and speaker quality, at the expense of the higher performance and screen quality offered by the ASUS ROG Strix G18.

The ASUS ROG Strix G18 has a better screen than the Lenovo IdeaPad Slim 7i for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18 has a high-resolution display with bright and vibrant colors making it ideal for everyday tasks and engineering software, but its lower refresh rate may not provide the best experience for gaming and 3D applications where smooth motion is key. The Lenovo IdeaPad Slim 7i, with its good color accuracy and decent resolution, suits both general purposes and professional design work, but like the ASUS, it may falter in gaming due to a less than optimal refresh rate. Hence, those looking for a laptop primarily for high-end gaming or 3D work should consider alternatives that prioritize high refresh rates.

"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."
"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."
