The Dell Inspiron 15 3511 is often less expensive and offers a balanced combination of features for general use, with reasonable battery life and performance from an Intel i5 processor. It's lighter, which makes it more portable, but has a standard screen size and resolution for everyday tasks. In contrast, the Dell Inspiron 16 5625 is somewhat more expensive, featuring a more powerful AMD Ryzen processor, which may handle intensive tasks and multitasking better. Its larger screen has a higher resolution and aspect ratio, providing a better experience for media and productivity, but as a result, it's heavier and might not be as easy to carry around. The Inspiron 16 also has a superior battery capacity, which could be important if you often work without access to power outlets. Give Feedback

PCMag
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."

Ultrabook Review
Derek Sullivan | January 2023
"I think there is fair value in the Inspiron 16 this year. Very little has changed with the laptop and my opinion hasn’t really changed either. In other words, I like it. Overall, I think the pros far outweigh the cons of this laptop and the price is certainly justifiable. I found this to be a great typer and I could potentially work all day on this machine, provided I don’t need a graphics card."
