If you're looking for superior performance for tasks like 3D rendering, machine learning, or gaming, the ASUS Zenbook Pro 16X could serve you well but at a higher cost and with potentially less portability due to its size and weight. In contrast, the Dell Inspiron 15 3511 would be more budget-friendly and easier to carry around, suitable for general use like browsing and document editing, but it might not handle intensive tasks as efficiently. Battery life is also a consideration – if you need longer unplugged usage, verify which one offers more battery longevity. Remember, the higher performance of the ASUS comes with increased weight and a higher price tag. Give Feedback

Marc Herter, Alex Wätzel | November 2023
"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."

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."
