For better performance, especially in tasks like 3D, machine learning, or engineering, the HP Dragonfly Pro 14's AMD Ryzen processor and better graphics will outperform the Dell Inspiron 15 3511. However, the Inspiron offers a larger screen which might be preferable for multitasking or if screen size is a priority, but it's also heavier, which impacts portability. If budget is a major concern, then the Dell Inspiron 15, being significantly less expensive, offers good value for general use and less intensive tasks. The HP boasts a longer battery life, making it a better travel companion, but this comes with a higher price tag. Give Feedback

The HP Dragonfly Pro 14" has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Inspiron 15 3511, with its fair screen quality, offers adequate resolution and brightness for everyday tasks but may not provide the color accuracy required for professional design work, and its lower refresh rate reduces the smoothness necessary for immersive gaming and 3D applications. Conversely, the HP Dragonfly Pro's good screen quality means its display likely offers better brightness and higher resolution, which translates to sharper images and more comfortable viewing for both casual and professional users, although it still falls short for gaming due to a lower refresh rate. Neither laptop is ideal for gaming or advanced 3D tasks where high refresh rates are crucial to prevent motion blur and provide a more fluid visual experience.

The HP Dragonfly Pro 14" and Dell Inspiron 15 3511 are both only fair for gaming and AI.
The Dell Inspiron 15 3511's gaming and 3D capabilities are limited by its integrated Intel Iris Xe graphics and a standard screen refresh rate of 60Hz, which may not deliver the smoothest gaming experience or optimal 3D performance. On the other hand, the HP Dragonfly Pro 14" has better gaming potential due to its more capable AMD Radeon 680M graphics, but it also has a screen refresh rate of 60Hz, suggesting that while it can handle gaming and 3D tasks better than the Dell, it still may not satisfy hardcore gamers or professionals seeking the highest frame rates.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"I’d say that the HP Dragonfly Pro checks off most of the boxes for this freelancer. It feels nice to use, is zippy and responsive, has great speakers, and even has a relatively sane price. Although it’s an unorthodox choice to pick AMD for this kind of machine, it’s clear that when Ryzen is given a chance to shine, it can kick a lot of butt."
