The ASUS ROG Zephyrus G15, while more expensive, offers significantly higher performance with its AMD Ryzen 9 processor and RTX 3070 graphics card, making it well suited for intensive tasks like 3D rendering, machine learning, and gaming. It features a higher resolution display and a faster refresh rate which is great for gaming and video editing work. On the flip side, the Lenovo IdeaPad 3 15" is far less expensive and still provides sufficient capability for general use and less demanding tasks with its Intel i3 processor and integrated graphics. The tradeoff with the Lenovo, however, is lower performance, a lower quality display, and less suitability for demanding software applications. The ASUS also typically offers better build quality and longer battery life but is heavier, making it less portable than the lighter Lenovo. Give Feedback

The ASUS ROG Zephyrus G15 has a better screen than the Lenovo IdeaPad 3 15" for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Zephyrus G15 boasts a high-resolution, bright display with a wide color gamut, providing sharp and vibrant images ideal for general use and professional engineering and design tasks where color accuracy is paramount. However, its refresh rate may not be high enough to satisfy gamers or 3D professionals who seek fluid motion and split-second response times. In contrast, the Lenovo IdeaPad 3 15" has lower resolution and brightness, and limited color range, which makes it less suitable across the board, particularly for tasks where visual detail and color fidelity are critical.

"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 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."
