The ASUS ROG Zephyrus G15, with its AMD Ryzen processor and Nvidia RTX 3070 graphics, is tailored for high performance in games and demanding applications, and it is more lightweight and portable, making it an excellent choice for those who prioritize gaming on the go. On the other hand, the Lenovo Legion 5i Pro, equipped with an Intel i7 processor and Nvidia RTX 4060 graphics, offers a slightly larger, taller screen which might be better for productivity tasks, but it's heavier and might have slightly less battery life, making it less convenient for mobility. Both laptops are well-suited for engineering tasks, but the choice between the two should be influenced by your preference for portability versus screen size and the slight differences in their graphics capabilities.

NotebookCheck

Florian Glaser | February 2021
"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."

PCMag

Brian Westover | August 2023
"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
