The ASUS TUF Gaming A15 is better suited for intensive tasks such as gaming, 3D modeling, or machine learning due to its higher-end graphics card, more RAM, and a stronger processor. It also has a higher refresh rate display, which is great for gaming, but it's heavier and bulkier, which reduces portability. Conversely, the Lenovo IdeaPad Slim 3 is more affordable and lighter, making it more portable and suitable for everyday use like web browsing, document editing, and light media consumption, but its lower-powered internal components will struggle with demanding applications. Furthermore, the IdeaPad has a longer battery life, beneficial for users needing to work on the go without frequent charging. Give Feedback

The ASUS TUF Gaming A15 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS TUF Gaming A15 has a solid resolution and brightness, making it good for general use and suitable for engineering with a color range that supports design work, yet its lower refresh rate can limit the smoothness desired in gaming and 3D applications. The Lenovo IdeaPad Slim 3 offers a decent display for everyday tasks and can handle engineering software, but its screen may not have the color fidelity needed for precise design work and lacks the high refresh rate necessary for optimal gaming and 3D rendering experiences. Both devices have compromises: while the ASUS may satisfy engineers and general users, gamers might find it lacking, and the Lenovo, while adequate for casual use, won't excel in professional design or high-end gaming.

How the ASUS TUF Gaming A15 and the Lenovo IdeaPad Slim 3 compare to other laptops
"With the release of the TUF Gaming A15, Asos have concentrated on the essentials: gaming performance. Our base version, which can be had for around $1,169, already provided enough power to play current games smoothly in a native resolution of 1080p and with maximum details - thanks to its new Nvidia GeForce RTX 4050 Laptop. If you utilize upscaling, then you can even manage to run ray tracing."
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."
