The ASUS ZenBook Pro Duo 15 is much more expensive and better suited for intensive tasks with a high-end CPU and GPU, doubling the memory and storage, and a superior OLED screen. It offers exceptional performance for 3D, machine learning tasks, and engineering software but it's heavier and not as portable as the Dell Inspiron 15 3525, which is budget-friendly, lighter, and still capable of general use and multitasking. The Dell has a standard IPS screen and adequate performance for everyday tasks but falls short for demanding applications. Give Feedback

The ASUS ZenBook Pro Duo 15 is good for gaming and AI, while the Dell Inspiron 15 3525 is only fair.
The ASUS ZenBook Pro Duo 15 is superior for gaming and 3D applications due to its high-end Nvidia RTX 3070 Ti graphics card, which significantly outperforms the integrated Vega 7 graphics found in the Dell Inspiron 15 3525. Although both have equal screen refresh rates, the GPU plays a more critical role in rendering complex graphics smoothly, making the ASUS vastly better suited for these tasks.

The ASUS Zenbook Pro Duo 15 has a better screen than the Dell Inspiron 15 3525 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro Duo 15 offers a high-resolution screen with a bright and vibrant display that's ideal for day-to-day tasks and professional design work, as it covers wider color gamuts ensuring accurate color reproduction, which is vital for engineering and design. On the other hand, despite its resolution, it lacks a high refresh rate which is crucial for a smooth gaming experience and 3D rendering. The Dell Inspiron 15 3525 has modest screen specs that provide an adequate display for general and engineering uses but falls short for gaming and 3D applications due to its standard refresh rate and limited color space coverage.

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."

"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."
