The ASUS Zenbook Pro 15 is typically more expensive than the Lenovo IdeaPad Slim 5i but offers better performance for 3D, machine learning, and gaming due to its more powerful AMD Ryzen processor and Nvidia RTX graphics. It also has superior display quality with an OLED panel and higher color coverage which is advantageous for visual tasks and entertainment. However, it's less portable and has lower battery life than the IdeaPad. The IdeaPad Slim 5i, with its Intel i5 processor and integrated graphics, is more affordable and more portable with better battery life, making it suitable for general use, but it's less capable for intensive tasks. The IdeaPad also has good screen color accuracy and a higher resolution display with a more productivity-friendly aspect ratio. Give Feedback

The ASUS Zenbook Pro 15 and Lenovo IdeaPad Slim 5i are both good for engineering and design, though the ASUS Zenbook Pro 15 is somewhat better.
The ASUS Zenbook Pro 15 is favored for engineering and design due to its powerful AMD processor and dedicated Nvidia RTX GPU, providing substantial performance for computationally demanding tasks, coupled with a vibrant OLED screen, which is great for color-sensitive work; however, it is heavier and has a shorter battery life compared to its counterpart. In contrast, the Lenovo IdeaPad Slim 5i also supports engineering and design tasks with a solid Intel processor and integrated Iris Xe graphics, a high resolution IPS screen for sharp visuals, superior keyboard quality, and longer fan noise control, making it a more portable option albeit with less graphical prowess.

The ASUS Zenbook Pro 15 and Lenovo IdeaPad Slim 5i are both good for general use.
The ASUS Zenbook Pro 15 is well-suited for general use due to its potent AMD Ryzen processor, ample RAM, and vibrant OLED screen which offers a richer visual experience, although it is slightly heavier and has longer battery life, making it less portable but more enduring on a single charge. On the other hand, the Lenovo IdeaPad Slim 5i, with its efficient Intel i5 processor and high-quality IPS display that provides a sharp image with a slightly different aspect ratio, is also fit for general use; it's lighter which increases portability but has a shorter battery life, meaning it may need charging more frequently during the day.

The ASUS Zenbook Pro 15 and Lenovo IdeaPad Slim 5i are both only fair for gaming and AI.
The ASUS Zenbook Pro 15 comes with a dedicated Nvidia RTX 3050 Ti GPU which is superior for gaming and 3D tasks compared to the Lenovo IdeaPad Slim 5i's integrated Intel Iris Xe graphics; however, both laptops have the same screen refresh rate, which is not ideal for high-framerate gaming. Additionally, while the Zenbook's OLED screen offers higher color accuracy and better contrast, making it more suitable for visually detailed work, the Slim 5i features an IPS display with a slightly higher resolution and different aspect ratio, offering a tradeoff between visual quality and performance depending on user preferences.

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"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."
