If performance, especially for 3D rendering, machine learning, and gaming, is a priority and you don't mind a heavier build and shorter battery life, the ASUS TUF Dash 15 is the better choice as it has a robust dedicated GPU and higher processing power. However, if you're looking for something more affordable, lighter, and with a longer battery life for general use and casual gaming, the Lenovo IdeaPad 5 15" with integrated graphics and a capable CPU should suffice. The Lenovo also includes a touchscreen, which the ASUS lacks, adding flexibility for everyday tasks and presentations. Give Feedback

The ASUS TUF Dash 15 is good for engineering and design, while the Lenovo IdeaPad 5 15" is only fair.
The ASUS TUF Dash 15 offers better performance for engineering and design tasks due to its higher-end CPU and GPU, greater RAM, and decent screen quality, key for software-intensive processes and graphic rendering. In contrast, the Lenovo IdeaPad 5 15" has a less powerful CPU and integrated GPU, less RAM, and lower screen quality, making it less suited for demanding engineering applications, though its lighter weight and slightly better battery life offer increased portability.

The ASUS TUF Dash 15 has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, and content creation.
The ASUS TUF Dash 15 likely offers a screen with good resolution and brightness, which are essential for clarity and comfortable viewing in general use, as well as reasonable color coverage supporting tasks in engineering and design. However, its screen may have a lower refresh rate, which detracts from the smooth visuals critical for gaming and 3D applications. On the other hand, the Lenovo IdeaPad 5 15" provides an adequate balance between resolution and brightness for daily tasks and color accuracy for engineering and design, but like the ASUS, it probably falls short on the high refresh rates demanded for optimal gaming and 3D experiences.

How the ASUS TUF Dash 15 and the Lenovo IdeaPad 5 15" compare to other laptops
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."
"The Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."
