When choosing between the ASUS Zenbook Flip S13 and the Dell Inspiron 15 3520, consider your priorities. The ASUS offers a higher resolution touchscreen, better battery life, and increased portability, with a higher performance in general use and engineering tasks due to its superior processor and RAM. It's sensitive to color accuracy for creative work but is more expensive. The Dell provides a larger screen and a more budget-friendly price, catering well to general use and its keyboard is decently rated. Its processor, however, is less powerful, making it less suited to demanding engineering tasks or high-end gaming. If outlook and performance in complex tasks are less important, the Dell might serve basic needs while saving money. Give Feedback

The ASUS Zenbook Flip S13 and Dell Inspiron 15 3520 are both only fair for gaming and AI.
The ASUS Zenbook Flip S13's Intel Iris Xe graphics and a 60Hz screen refresh rate offer a fair balance between visual fidelity and fluid motion for gaming and 3D applications, but with limited frame rates due to the refresh rate. On the other hand, the Dell Inspiron 15 3520's Intel UHD Graphics provides basic graphic capabilities, and while its higher 120Hz screen refresh rate allows for smoother visuals, it's constrained by the GPU's modest performance.

Charles Jefferies | January 2023
"The Asus Zenbook S 13 Flip is an ultra-sleek 2-in-1 convertible. A gorgeous OLED screen and lightweight magnesium chassis make this convertible a traveller’s dream. Its SSD isn’t fast, but it won’t hold you back in everyday use. Its battery life also isn’t class leading, but it’s hardly off the pace. Overall, the Zenbook S 13 Flip OLED holds its head high in the premium convertible category and is a smaller alternative to the Spectre x360 13.5 and the Yoga 9i Gen 7."

"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."
