If you're looking for a laptop that provides high processing power and better performance for tasks like 3D rendering, machine learning, and other engineering uses with a top-tier graphics card, the Lenovo Legion 7i Pro is an excellent choice, albeit with a higher price and less portability due to its weight. However, if you value a balance between performance, a quality screen for general use, and portability, along with a more affordable price, the ASUS ROG Zephyrus G15 is a strong contender, offering substantial performance for most tasks, good build quality, and longer battery life. Both laptops are not touchscreen and feature similar display sizes and resolutions but differ in aspect ratios and refresh rates, with the Lenovo offering a higher refresh rate which can benefit fast-paced gaming experiences.

"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."
