The ASUS ZenBook Pro Duo 15 is suitable if you need high performance for intensive tasks like 3D rendering, machine learning, or engineering applications, but it's heavier and less portable. It also offers a dual-screen setup which may enhance productivity. Conversely, the Lenovo IdeaPad Slim 7i Pro is more portable, less expensive, and better for everyday use with a better battery life, but is less powerful. It may struggle with demanding tasks due to its more modest processing and graphics capabilities. If you prioritize mobility and value over high-end performance, the Lenovo is a solid choice; for power-intensive uses, the ASUS is recommended. Give Feedback

The ASUS ZenBook Pro Duo 15 is very good for general use, while the Lenovo IdeaPad Slim 7i Pro is good.
The ASUS ZenBook Pro Duo 15 is very good for general use due to its high-quality OLED screen, powerful i9 processor, and significant RAM, which make multitasking and high-resolution media consumption a pleasure, albeit with a trade-off in portability due to its weight and size. The Lenovo IdeaPad Slim 7i Pro, meanwhile, is good for general use, featuring a still respectable screen and competent i5 processor, in a much more portable and lighter package with better battery life, though it compromises on performance and screen real estate in comparison.

The ASUS ZenBook Pro Duo 15 is good for gaming and AI, while the Lenovo IdeaPad Slim 7i Pro is only fair.
The ASUS ZenBook Pro Duo 15 comes with a high-performance Nvidia RTX 3070 Ti graphics card suitable for gaming and 3D tasks but has a standard screen refresh rate, while the Lenovo IdeaPad Slim 7i Pro has a lesser performing Intel Iris Xe graphic solution, albeit with a higher screen refresh rate, which may not deliver as high-quality gaming and 3D experiences.

The ASUS ZenBook Pro Duo 15 is excellent for engineering and design, while the Lenovo IdeaPad Slim 7i Pro is good.
The ASUS ZenBook Pro Duo 15 excels in engineering and design use due to a more powerful i9 processor, double the RAM, and a high-end Nvidia GPU which outmatches the Lenovo IdeaPad Slim 7i Pro's i5 processor and integrated graphics; this results in better overall performance especially for graphically intensive tasks. Furthermore, the ASUS offers superior screen quality with its OLED display, having a higher resolution and color accuracy, although it is less portable and potentially noisier under load compared to the lighter and quieter Lenovo, which still maintains good quality in both screen and build albeit with somewhat lower specs.

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

Allen Ngo | October 2021
"The main selling point of the IdeaPad Slim 7i Pro versus a regular IdeaPad Slim 7 is its faster Core H-series CPU. In reality, the Core i7-11370H is only marginally faster than the U-series Core i7-1165G7 to the point where most users are not likely to notice the benefits. The slight performance uptick comes at the cost of slightly higher power consumption as well meaning owners will have to deal with potentially warmer temperatures or louder fans to compensate. Unless if you happen to be a power user, then the regular non-Pro model will be more than enough. Once you go 90 Hz, you can't go back."
