Considering your options, the ASUS ZenBook Pro Duo 15 is a high-performance device suitable for intensive tasks like 3D rendering, machine learning, and gaming with its robust processor and advanced graphics card. It also boasts a high-resolution OLED screen, but is heavier and less portable, making it less ideal for frequent travel. On the other hand, the Dell Inspiron 15 3520 is more budget-friendly, lighter, and more portable, with a decent screen for everyday tasks. However, it has lesser storage, memory, and a less powerful processor and graphics, making it less suitable for demanding software and gaming. Your choice should ultimately align with your primary needs: sophisticated performance and screen quality with the ASUS or portability and affordability with the Dell. Give Feedback

The ASUS ZenBook Pro Duo 15 is very good for general use, while the Dell Inspiron 15 3520 is only fair.
The ASUS ZenBook Pro Duo 15 excels in general use with its powerful Intel i9 processor, abundant RAM, and high-quality OLED screen, whereas the Dell Inspiron 15 3520, with its modest Intel i3 processor and standard IPS screen, aligns with more casual needs and budget-conscious users. While the Dell offers great portability and excellent heat management, the ASUS leads in performance at the expense of heavier weight and shorter battery life.

The ASUS ZenBook Pro Duo 15 is good for gaming and AI, while the Dell Inspiron 15 3520 is only fair.
The ASUS ZenBook Pro Duo 15 offers superior gaming and 3D performance primarily due to its high-powered Nvidia RTX 3070 Ti graphics card and OLED screen technology, which are better suited for graphic-intensive tasks than the Dell Inspiron 15 3520's Intel UHD graphics and IPS display. While the Dell has a higher screen refresh rate that can be advantageous for smooth motion, the overall capability provided by ASUS's better GPU and screen quality renders it more effective for these uses.

The ASUS ZenBook Pro Duo 15 is excellent for engineering and design, while the Dell Inspiron 15 3520 is only fair.
The ASUS ZenBook Pro Duo 15 outperforms the Dell Inspiron 15 3520 in engineering and design due to its higher-end CPU, significant RAM advantage, superior dedicated GPU, and an OLED screen with better color accuracy and resolution. However, the ZenBook Pro Duo is heavier and slightly thicker, affecting portability, while the Inspiron 15 offers less power but is lighter and quieter, which may be considered if mobility and operating noise are priorities.

The ASUS Zenbook Pro Duo 15 has a better screen than the Dell Inspiron 15 3520 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro Duo 15's high resolution and brightness, along with advanced panel technology, ensure vivid and sharp visuals for everyday tasks and professional design work, with the wide color gamut supporting precision in engineering and design applications. However, its lower refresh rate can detract from the smoothness required in fast-paced gaming or 3D rendering. On the other hand, the Dell Inspiron 15 3520 offers adequate resolution and brightness for general and engineering use but falls short in providing the color accuracy needed for professional design and the high refresh rate desired for gaming and 3D environments.

"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. Plus, those alternatives are much more enjoyable after work."
