If you prioritize high performance for tasks like 3D modeling, machine learning, or gaming, the ASUS ROG Flow Z13 offers a more powerful processor and dedicated graphics, which Dell Inspiron 15 3511 lacks. However, the Inspiron is more affordable and offers a larger screen, potentially making it better for general use where a big display and budget are key concerns. The ASUS is more versatile, doubling as a tablet due to a detachable keyboard, but this feature along with its hardware make it pricier. The Inspiron, while less expensive and with a modest performance, might offer a longer battery life suitable for everyday tasks without the need for high computing power. Give Feedback

The ASUS ROG Flow Z13 has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow Z13's screen excels in general use and engineering thanks to its high resolution and brightness, providing crisp and clear visuals, along with excellent color coverage that ensures accurate color representation for design tasks. However, its lower refresh rate hinders its gaming performance, meaning fast-paced 3D games won't appear as smooth. On the other hand, the Dell Inspiron 15 3511, with its adequate resolution and brightness, offers a fair display for everyday tasks and engineering work, but like the ASUS, its screen falls short for gaming due to a lower refresh rate and less vibrant color range.

How the ASUS ROG Flow Z13 and the Dell Inspiron 15 3511 compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
