The ASUS ROG Flow Z13 offers significantly higher 3D rendering and machine learning capabilities with a dedicated Nvidia GPU, making it suitable for gaming and intensive engineering tasks. However, it is less portable due to its weight and has a shorter battery life. In contrast, the Lenovo IdeaPad Slim 5i has longer battery life and is more portable thanks to its lighter weight, though it compromises on performance with integrated graphics, which is more suited for general use and lighter tasks. The Flow Z13 comes at a higher price, while the IdeaPad Slim 5i is relatively more affordable. Give Feedback

The ASUS ROG Flow Z13 is very good for engineering and design, while the Lenovo IdeaPad Slim 5i is good.
The ASUS ROG Flow Z13 outshines the Lenovo IdeaPad Slim 5i for engineering and design, chiefly due to its superior Intel i9 processor, more powerful Nvidia RTX 4050 GPU, and a higher resolution, brighter display, which all contribute to better performance and screen quality. While both models feature good portability and adequate amounts of RAM, the Lenovo IdeaPad Slim 5i, despite having a larger screen, falls short on core engineering requirements with its less robust Intel i5 processor and integrated graphics, though it does offer a somewhat quieter operating noise and a slightly longer battery life.

How the ASUS ROG Flow Z13 and the Lenovo IdeaPad Slim 5i compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
