The ASUS ROG Zephyrus G15 is good for gaming and AI, while the Lenovo IdeaPad Slim 7i is only fair.
The ASUS ROG Zephyrus G15 outperforms the Lenovo IdeaPad Slim 7i in gaming and 3D tasks chiefly because of its superior Nvidia RTX 3070 GPU and higher screen refresh rate of 165Hz compared to the Slim 7i's integrated Intel Iris Xe graphics and 60Hz refresh rate. Although both have capable CPUs and high-quality IPS screens, the GPU and refresh rate are critical for rendering complex graphics and providing smooth visuals, making the Zephyrus G15 better suited for these demands.

How the ASUS ROG Zephyrus G15 and the Lenovo IdeaPad Slim 7i 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."
"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
