The ASUS ROG Strix G15 is more suitable for intensive gaming and engineering tasks due to its stronger GPU and CPU, but it is heavier, less portable, and has shorter battery life compared to the Lenovo IdeaPad Slim 7i Pro. The IdeaPad, being lighter with a longer battery life and a high-resolution touchscreen, is a better option for general use, and its performance is sufficient for everyday tasks and light engineering work. The Lenovo is also less expensive but may not handle demanding 3D or machine learning tasks as well as the ASUS. The choice depends on whether performance or portability and battery life are your priority, as well as your budget constraints. Give Feedback

How the ASUS ROG Strix G15 and the Lenovo IdeaPad Slim 7i Pro compare to other laptops
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
