The Dell Precision 5470 and Dell Inspiron 15 3520 are both only fair for gaming and AI, though the Dell Precision 5470 is somewhat better.
The Dell Inspiron 15 3520 is equipped with an integrated Intel graphics card, which generally offers modest performance for gaming and 3D applications, and a higher screen refresh rate that can make gameplay smoother. Conversely, the Dell Precision 5470 features a dedicated Nvidia graphics card, which provides significantly better performance for gaming and 3D-intensive tasks but has a lower refresh rate that may affect motion fluidity in fast-paced games.

The Dell Precision 5470 is good for engineering and design, while the Dell Inspiron 15 3520 is only fair.
The Dell Precision 5470 outshines the Dell Inspiron 15 3520 for engineering and design largely due to its superior main processor and graphics unit, which are crucial for intensive tasks, along with double the RAM and a brighter, higher resolution screen that benefits detailed work. While the Inspiron offers a larger screen and good portability, the Precision's additional RAM, professional-grade GPU, and higher quality display panel provide the performance and clarity needed for complex engineering software, even if it comes with a slightly higher weight.

The Dell Precision 5470 has a better screen than the Dell Inspiron 15 3520 for general use, engineering and design, content creation, and software development.
For general use, the Dell Inspiron 15 3520's screen might not be as sharp or vivid due to its resolution and brightness levels not matching higher-end screens, while the Dell Precision 5470's superior panel type, higher resolution, and greater brightness offer a clearer and more comfortable viewing experience. For engineering and design tasks, the Precision 5470's display covers a wider color gamut, providing more accurate colors which are crucial for detail-oriented work, unlike the Inspiron 15 3520 which may fall short in color accuracy and range. Gamers and professionals working with 3D graphics will find both laptops underwhelming as their screens do not have the high refresh rates needed for smooth motion, although the higher resolution of the Precision 5470 still provides a moderate advantage in clarity and detail.

"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."
"The Dell Precision 5470 is a mobile workstation that's far more portable than most alternatives. Between its slim 14-inch design and top-quality MIL-STD 810H build, it's one of the best options around for taking professional-grade performance on the road or to the job site. There are tradeoffs for its portability, and users of the most demanding, graphics-intensive applications will need to carry something heavier. But the Dell's exceptional battery life underscores its desirability as the most portable workstation we've seen."
