If performance for 3D rendering, machine learning, or engineering tasks is a priority, and you're open to a less portable option with a higher price, the Lenovo LOQ 15 with the Nvidia RTX 4050 GPU would be a better fit. However, if you value longer battery life, greater portability, and a lower cost, and your usage is more aligned with general activities, the Lenovo IdeaPad Slim 5i would serve you well. Keep in mind, the IdeaPad Slim 5i's built-in graphics are not intended for intensive gaming or heavy graphics tasks, whereas the LOQ 15 can handle such demands with its dedicated gaming-class GPU.

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."

"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."
