The ASUS Vivobook 15 offers moderate performance with an Intel i3 processor suitable for general use, while the Lenovo IdeaPad Slim 3 comes with a larger storage capacity and a touchscreen feature. The IdeaPad has a longer battery life, which could be significant if you often work on the go. In terms of graphics, both laptops are not designed for intensive gaming or heavy 3D work. The Vivobook's build is slightly heavier compared to the IdeaPad's, so consider the IdeaPad if weight is a critical factor for you. Asus and Lenovo have similar keyboard and general use performance, but Lenovo scores slightly higher in portability due to its lighter build and extended battery life. Give Feedback

The Lenovo IdeaPad Slim 3 has a better screen than the ASUS Vivobook 15 for content creation, and software development.
For general use, both the ASUS Vivobook 15 and the Lenovo IdeaPad Slim 3 have screens that provide adequate clarity and brightness, but may not offer the sharpness and vibrant colors seen in higher-end screens. In engineering and design, the importance of color accuracy means neither laptop's display quite meets the standards required for professional color work, as they lack the wider color gamuts professionals look for. For 3D and gaming, the absence of high refresh rates and moderate resolution on both models results in less fluid motion and detail, making them less suitable for these visually demanding activities.

How the ASUS Vivobook 15 and the Lenovo IdeaPad Slim 3 compare to other laptops
"The Asus VivoBook 15 is a quiet office notebook with a strong screen. However, the VivoBook 15 still has room for improvement. Office and internet applications as well as simple games do not pose any major challenges for the VivoBook - this is ensured by the built-in combination of Ryzen 7 5700U APU and 16 GB of RAM. Heat and noise emissions are acceptable. But, the laptop has weaknesses that should not be present at this level: lack of keyboard lighting, a slow memory card reader, no fast USB-C port (USB 3.2 Gen 2 or Thunderbolt 4) with Power Delivery and DisplayPort. Battery runtimes can only be described as average."
Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
