The ASUS ROG Strix G15 Advantage Edition is suited for those who need higher performance for gaming or intensive engineering and 3D tasks, it has a more powerful processor, better graphics, and a larger battery, but it's heavier and less portable. On the other hand, the Lenovo IdeaPad Slim 3, while more affordable and offering better portability due to its lighter weight and longer battery life, is equipped for general use and light tasks given its less powerful processor and integrated graphics. So, your choice should hinge on whether performance or portability and price is your priority. Give Feedback

The ASUS ROG Strix G15 Advantage Edition is very good for engineering and design, while the Lenovo IdeaPad Slim 3 is only fair.
The ASUS ROG Strix G15 Advantage Edition outperforms the Lenovo IdeaPad Slim 3 for engineering and design use due to its superior AMD Ryzen 9 processor, double the RAM, and a more powerful dedicated GPU, all of which are crucial for running demanding applications smoothly. Additionally, the ASUS model has a significantly better screen quality in terms of brightness and color space coverage which is essential for detailed and color-accurate work, although it is less portable and noisier under load than the lighter Lenovo, which has a lesser performance CPU and integrated graphics.

The ASUS ROG Strix G15 Advantage Edition has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, and content creation.
The ASUS ROG Strix G15 Advantage Edition offers a display that's sharp and bright enough for everyday tasks and detailed enough for engineering software, also covering a wide range of colors, which benefits professional design work. However, its relatively lower refresh rate compared to specialized gaming laptops makes it less optimal for the fast-paced visuals in gaming and 3D rendering. In contrast, the Lenovo IdeaPad Slim 3 provides adequate resolution and brightness for routine tasks and casual design work but lacks the advanced color range and high refresh rate needed for professional engineering and smooth gaming experiences.

How the ASUS ROG Strix G15 Advantage Edition and the Lenovo IdeaPad Slim 3 compare to other laptops
"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."
Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
