The ASUS Vivobook 15X offers solid performance, with a focus on general use and some gaming, but the Dell Inspiron 15 3511 has a larger storage capacity and more memory which could be more beneficial for intensive tasks like engineering or working with large datasets. The Dell also incorporates Intel graphics, which may provide a smoother experience in graphic-intensive applications compared to the ASUS's integrated AMD graphics. While the ASUS is pricier, it's lighter and offers a white color option if aesthetics are a concern. Both have similar size displays and are equipped with Windows 11 Home, but the Dell appears to have been on the market longer, which could mean it's been more time-tested. Give Feedback

The Dell Inspiron 15 3511 has a better screen than the ASUS Vivobook 15X for content creation, and software development.
For general use, both laptops offer displays that provide sufficient resolution and brightness for everyday tasks like browsing the web or working with office applications, however, their screens may not be as vibrant or crisp as higher-end models. In the context of engineering and design, both laptops have screens that lack wide color gamuts, which means professionals dealing with precise color work might find the color accuracy limited. When it comes to 3D or gaming, the screens on these laptops have lower refresh rates, which can result in less fluid motion and a reduced experience in fast-paced scenarios compared to laptops with higher refresh rates.

The Dell Inspiron 15 3511 and ASUS Vivobook 15X are both only fair for gaming and AI.
The ASUS Vivobook 15X and the Dell Inspiron 15 3511 are both equipped with integrated GPUs that are suitable for light gaming and basic 3D applications but may struggle with more demanding tasks, and they share a standard screen refresh rate of 60Hz which is not ideal for high-end gaming where higher refresh rates can provide smoother visuals. While the Vivobook 15X uses an AMD GPU and the Inspiron 15 3511 leverages Intel's Iris Xe graphics, neither is as powerful as dedicated gaming GPUs, and their similar IPS displays with 1080p resolution offer decent screen quality but don't stand out for gaming purposes.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."

"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."
