The ASUS Zenbook 14X OLED typically costs less and offers an OLED screen with higher resolution and touch support, which is great for vibrant colors and multimedia use, but it has a shorter battery life compared to the Dell Inspiron 14 5420. The Dell has a longer battery life and more RAM, which helps with multitasking and complex tasks, yet it comes with an IPS screen with no touch option and a dedicated graphics card that may perform better with certain types of 3D workloads or light gaming, albeit at a higher price. The ASUS is slightly heavier and has a greater selection of USB-C ports, while the Dell offers Windows 11 Pro and potentially better heat management. If visual work and portability are priorities, consider the ASUS; if longer battery life and multitasking are more important, the Dell might be a better fit. Give Feedback

The ASUS Zenbook 14X OLED and Dell Inspiron 14 5420 are both only fair for gaming and AI.
The ASUS Zenbook 14X OLED has an integrated GPU and a high screen refresh rate, offering smoother visuals but limited gaming and 3D performance due to the less powerful graphics processor. In contrast, the Dell Inspiron 14 5420 comes with a dedicated Nvidia MX570 GPU which is better for gaming and 3D applications, but has a lower refresh rate, meaning less fluid motion compared to the ASUS' high-refresh rate display.

"While one of the more budget-friendly configurations of the Asus Zenbook 14X OLED may make a compelling case as a top value pick, it’s difficult to be disappointed with the more expensive model we reviewed here. At its core, for all models, it’s a luxury-built laptop with extreme portability and a gorgeous OLED display. Our unit rocks with a snappy Core i9 processor for getting real work done, and the discrete GPU—even if it has a clear power ceiling—is a bonus for creative pros."
