If portability and battery life are top priorities, the Dell Inspiron 14 7425 stands out with its smaller, lighter build and longer battery life, also offering a higher resolution screen and the flexibility of a 2-in-1 design as it can double as a tablet. However, if you're looking for a larger display, more storage, and a potentially more powerful processor for intensive tasks, the Dell Inspiron 15 3511 can deliver that at a lower price point. It lacks the tablet mode and has a shorter battery life, which can be important if you're often on the move. Give Feedback

The Dell Inspiron 14 7425 has a better screen than the Dell Inspiron 15 3511 for general use, while the Dell Inspiron 15 3511 has a better screen for software development.
When considering general use, both the Dell Inspiron 14 7425 and Inspiron 15 3511 have fair screens due to adequate resolution and brightness, but they may not have outstanding panel types that offer wide viewing angles and color accuracy. For engineering and design, their fair quality stems from acceptable resolution and brightness, but they lack the extensive color gamut coverage needed for precise color work. For gaming and 3D applications, both models fall short because while they have satisfactory resolution and panel type, they don't offer the high refresh rates required for smooth motion and fast-paced visuals.

The Dell Inspiron 14 7425 has a price of $800 and the Dell Inspiron 15 3511 costs $560.
The Dell Inspiron 15 3511 and Dell Inspiron 14 7425 are both good for general use.
The Dell Inspiron 14 7425 is well-suited for general use due to its balance of a powerful CPU, sufficient RAM, and high screen quality in a lightweight, portable design with decent battery life. In contrast, while the Dell Inspiron 15 3511 also offers a robust CPU and more RAM, which is beneficial for multitasking, its larger screen and higher storage capacity are packaged in a slightly heavier build that comes with a trade-off in battery life, making it less portable but more suited for stationary use with extensive storage needs.

The Dell Inspiron 14 7425 and Dell Inspiron 15 3511 are both only fair for gaming and AI.
The Dell Inspiron 14 7425 and Inspiron 15 3511 are both "fair" for gaming and 3D due to their integrated GPUs, which can handle some gaming and 3D tasks but won't provide the high performance of dedicated gaming GPUs, and both have a standard screen refresh rate of 60Hz, which is adequate for casual gaming but not ideal for fast-paced games that benefit from higher refresh rates. While the former has a slightly higher screen pixel density, offering sharper images, and the latter has a larger screen size that could enhance the gaming experience, neither excels in terms of the essential graphics performance and screen refresh rate that serious gaming and 3D applications demand.

Although they have very similar scores, PerfectRec considers Dell Inspiron 15 3511 to be good for engineering and design, while the Dell Inspiron 14 7425 is only fair.
The Dell Inspiron 14 7425's AMD Ryzen processor, 16GB of RAM, and integrated Vega 8 graphics work well for engineering and design tasks, and its IPS screen with higher resolution and brightness aids in visual clarity. Conversely, the Dell Inspiron 15 3511 offers more RAM at 32GB and a larger 15.6-inch screen, but with a lower resolution and brightness, which slightly impacts screen quality, albeit offering more space for multitasking and design work. Both laptops balance portability with good keyboards, but the 7425's higher portability may be more appealing for on-the-go use, while the 3511's additional RAM is beneficial for more intensive software.

How the Dell Inspiron 14 7425 and the Dell Inspiron 15 3511 compare to other laptops
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."
"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."
