The ASUS ZenBook Pro Duo 15 offers top-tier performance with its i9 processor and RTX 3070 Ti graphics card, making it ideal for demanding tasks like 3D rendering, machine learning, and engineering work. Its OLED display with 4K resolution and touchscreen capability provides vibrant colors and sharp visuals, which is excellent for creative professionals. However, it's heavier and less portable, with a lower refresh rate of 60Hz, which might not be as smooth for gaming as the Lenovo's 144Hz. On the other hand, the Lenovo LOQ 15i is more budget-friendly and portable, with a longer battery life and a higher refresh rate screen that's better suited for gaming. Its i7 processor and RTX 4060 GPU still offer solid performance for general use and gaming, though it may not handle intensive engineering tasks as efficiently as the ASUS. The Lenovo also lacks the premium features of the ASUS, such as the secondary screen and OLED display, and has less RAM, which could impact multitasking performance. In summary, if you prioritize performance and display quality for professional work and are willing to compromise on portability and price, the ASUS ZenBook Pro Duo 15 is the way to go. However, if you're looking for a more affordable and portable laptop with a focus on gaming and general use, the Lenovo LOQ 15i would be a better fit. 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."

"Even after a short time with the LOQ 15, you'll find it has a lot going for it, but ultimately it's just "good"—not quite a star. The performance is respectable for the hardware it’s running, but Lenovo had to make some design sacrifices to trim the price. One of the better aspects is the keyboard, making it one of the better low-cost gaming laptops to actually put your hands on."
