The ASUS TUF Dash 15 is generally more expensive and better suited for intensive gaming, 3D rendering, and engineering applications thanks to its higher performance graphics card. It is less portable than the Lenovo IdeaPad Slim 5i, which is lighter and offers a better battery life but has less powerful graphics, making it more suitable for general use and less demanding tasks. The Lenovo's higher screen resolution and aspect ratio may also offer a better experience for productivity tasks. If budget is a key concern and you do not require high performance for gaming or professional applications, the Lenovo could be a better choice. Give Feedback

For general use, the ASUS TUF Dash 15 offers a balance of resolution and brightness, providing a clear and vivid display, while the Lenovo IdeaPad Slim 5i, though adequate, may not be as crisp or bright. In the realm of engineering and design, the ASUS shines with a wider range of colors, particularly important for detailed and color-sensitive work, whereas the Lenovo's color range is more limited, affecting precision. When it comes to 3D and gaming, the lower refresh rate of both laptops means they may not provide as fluid motion as models designed specifically for these purposes, with the ASUS also falling short despite its other screen qualities.

The ASUS TUF Dash 15 and Lenovo IdeaPad Slim 5i are both good for general use.
The ASUS TUF Dash 15 offers a more powerful gaming-oriented CPU and GPU combination, making it suitable for both general and intensive use, with a high refresh screen enhancing visual fluidity, but this results in a bulkier frame and slightly shorter battery life. Conversely, the Lenovo IdeaPad Slim 5i trades off gaming capabilities for a lighter and slightly longer-lasting battery, paired with an ample high resolution and high brightness display, and a more tactile keyboard, which together cater well to everyday tasks and media consumption.

"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 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."
