Dell Inspiron 15 3511 vs Dell Inspiron 16 5620

The Dell Inspiron 15 3511, with its fair screen quality, offers a resolution and panel type that are suitable for everyday tasks and basic engineering applications, but its brightness may be just adequate and not ideal in very bright environments or for those who prioritize crisp visuals. Similarly, the Dell Inspiron 16 5620 provides an acceptable display for routine activities and casual design work, though professionals may notice limitations in color accuracy due to less coverage of professional color gamuts like DCI-P3 and Adobe RGB. Both models fall short for gaming and 3D use where smooth visuals are crucial, as they lack high refresh rates that enhance fluidity and reduce motion blur, making them less than ideal for fast-paced or highly detailed visual work.

Battery life estimate is based on a mix of common use patterns. More portable and higher performing laptops tend to have less battery life.

PerfectRec’s Build Quality Score incorporates case materials, display and keyboard flex, hinge quality, and overall reliability.

The Dell Inspiron 15 3511 suits general use with ample RAM and a capable CPU, ensuring smooth multitasking and general responsiveness, while its slightly smaller screen and lighter weight favor portability. On the other hand, the Dell Inspiron 16 5620, with a larger screen offering higher resolution and aspect ratio, improves content display and productivity space, and its longer-lasting battery life makes it more suitable for extended use away from power sources. Both models boast quality keyboards and manage heat well, with the Inspiron 16 5620 edging out with better speakers and a quieter operation.

The Dell Inspiron 15 3511 and Dell Inspiron 16 5620 are both equipped with integrated Intel Iris Xe graphics and have a screen refresh rate of 60Hz, which are sufficient for casual gaming and entry-level 3D applications but may not offer the high performance required for more intensive gaming or 3D tasks that dedicated GPUs and higher refresh rates can provide. The Inspiron 16 5620 has a slightly larger screen and higher resolution, offering better screen quality, but both laptops have similar processing power, with the Inspiron 16 5620 featuring a newer generation CPU that could offer some improvements in efficiency.
