The ASUS TUF Gaming F15, being more expensive, offers a higher performance with a better processor and graphics card, making it suitable for intensive gaming, 3D rendering, and engineering tasks. It also has a robust build quality but is heavier, impacting its portability. On the other hand, the Lenovo IdeaPad Slim 3 is a budget-friendly option that's lighter and has a longer battery life, ideal for general use. It's equipped with a touchscreen and is more portable due to its lower weight. However, its performance is less suited for demanding software applications related to gaming or engineering. Keep in mind that if battery life and portability are your top priorities, and your tasks are relatively light, like web browsing, office applications, and media consumption, the Lenovo might serve you well. But for power-intensive tasks and better gaming experiences, the ASUS is the better choice. Give Feedback

The ASUS TUF Gaming F15 and Lenovo IdeaPad Slim 3 are both good for general use, though the ASUS TUF Gaming F15 is somewhat better.
The ASUS TUF Gaming F15 offers better performance for general use with its Intel i7 processor and 16GB of RAM, along with a dedicated Nvidia RTX GPU, while the Lenovo IdeaPad Slim 3, with an AMD Ryzen 3 processor and 8GB of RAM, may handle everyday tasks but could struggle with more demanding applications. The F15's gaming-centric design and robust build also enhance its screen quality and heat management, but its weight and shorter battery life make it less portable than the lighter IdeaPad Slim 3, which boasts longer battery life but compromises on keyboard quality and intense gaming suitability.

The ASUS TUF Gaming F15 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, and content creation.
For general use, the ASUS TUF Gaming F15 provides a pleasing visual experience with its resolution and brightness, making it suitable for everyday tasks like browsing and video streaming, while the Lenovo IdeaPad Slim 3 offers adequate screen quality with respectable brightness and resolution for similar general activities. Engineering and design professionals may find the color accuracy and range lacking in both the ASUS TUF Gaming F15 and Lenovo IdeaPad Slim 3, as high-end color gamuts are crucial for precision in color-critical work and neither laptop excels in this aspect. When it comes to 3D applications and gaming, the ASUS TUF Gaming F15's screen falls short due to a lower refresh rate which is vital for smooth visuals, and although both laptops may handle less demanding games, serious gamers and 3D designers should seek out laptops with higher refresh rates and better panel technologies.

How the ASUS TUF Gaming F15 and the Lenovo IdeaPad Slim 3 compare to other laptops
"Aside from all the chassis updates, the new TUF Gaming is most notable for its much higher TGP target of 140 W compared to only 95 W on the previous generation. PC makers everywhere are using the same GeForce GPUs this year since Nvidia has yet to launch the successor to the mobile RTX 3000 series. The more demanding processors of the new TUF Gaming has directly impacted battery life and the size of the AC adapter. Don't expect runtimes to be longer than on the previous generation under most conditions and be prepared to carry around an even larger AC adapter than before."
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."
