The ASUS ZenBook Pro Duo 15 offers a high-resolution OLED touchscreen and is more powerful, suited for tasks like 3D rendering and machine learning. Its unique dual-screen design can enhance productivity but comes at the cost of being heavier and having a shorter battery life. The Lenovo Legion Slim 7 16", while also powerful, has a higher refresh rate display and a lighter build, optimizing it for gaming and portability. It lacks the touchscreen and the top-tier display colors of the ASUS but balances this with a better keyboard and higher portability. Choose the ASUS for a premium dual-screen experience with intense workloads and the Lenovo for gaming and travel-friendly usage. Give Feedback

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."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
