When choosing between the ASUS ROG Zephyrus G15 and the Dell Inspiron 15 3511, the main considerations are performance, budget, and intended use. If top performance for gaming or demanding engineering software is a priority and you're less concerned about cost, the ASUS with its higher-end CPU and GPU excels in power and display quality for these purposes. In contrast, the Dell Inspiron is priced lower, offers adequate performance for general use, and could be a better match if you're looking to save money and don't require the high graphics or processing capabilities of the ASUS. Portability is slightly better with the Dell since it's lighter, but the difference is small. Battery life also varies, with the ASUS providing longer usage between charges, which might be important if you're often on the go. Keep in mind, the premium features of the ASUS also contribute to its higher expense compared to the Dell. Give Feedback

"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

"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."
