The ASUS ROG Zephyrus G15 is good for gaming and AI, while the Lenovo IdeaPad Gaming 3 is only fair.
The ASUS ROG Zephyrus G15 is better suited for gaming and 3D applications because it houses a more powerful Nvidia RTX 3070 GPU and offers a higher screen refresh rate, which leads to smoother visuals during high-speed gaming or 3D rendering. In contrast, the Lenovo IdeaPad Gaming 3 includes a lower-tier Nvidia RTX 2050 GPU and a lower screen refresh rate, which means it will provide a less fluid experience during demanding gaming or 3D tasks.

The ASUS ROG Zephyrus G15 has a better screen than the Lenovo IdeaPad Gaming 3 for general use, gaming and AI, engineering and design, and content creation.
The ASUS ROG Zephyrus G15 has a display that provides high resolution and brightness, making it excellent for general use and suitable for precise engineering tasks due to its wide color gamut. However, its lower refresh rate compared to specialized gaming laptops affects its performance in gaming and 3D applications where smooth motion is paramount. On the other hand, the Lenovo IdeaPad Gaming 3, while offering satisfactory resolution and brightness for daily tasks and engineering software, also falls short for gaming and 3D work because its refresh rate isn't high enough to deliver the best experience in fast-paced scenarios.

How the ASUS ROG Zephyrus G15 and the Lenovo IdeaPad Gaming 3 compare to other laptops
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
"The Lenovo IdeaPad Gaming 3 is one of the most powerful RTX 3050 Ti laptops. If you disregard the mediocre quality of the case in terms of the material and workmanship, Lenovo has created a successful budget gaming laptop with the IdeaPad Gaming. Thanks to high TDPs and constant performance development, the Core i5-12500H and GeForce RTX 3050 Ti are able to show their full power, while in contrast, the (mostly slower) competitors deliver a better battery life. However, hardly any of the alternative laptops are able to reach the image quality of the Gaming 3. Most of the competitors are left behind in terms of the color space and brightness."
