The ASUS Vivobook 15X has more storage but less RAM compared to the LG Ultra 13, which may handle multitasking better due to more RAM. The Vivobook has a larger 15.6-inch screen suitable for productivity and entertainment but is heavier, making it less portable than the lighter and more compact Ultra 13 with its 13.3-inch screen. The Ultra 13 also offers a slightly better battery capacity. If performance for engineering and 3D tasks is a priority, the Vivobook's processor might be a better fit, there will be a performance tradeoff against the Ultra 13's better portability and battery life.

The LG Ultra 13 has a better screen than the ASUS Vivobook 15X for general use, gaming and AI, engineering and design, and content creation.
The ASUS Vivobook 15X's display offers adequate resolution and brightness for everyday tasks and sufficient color accuracy for engineering work, but its lower refresh rate might not be ideal for the fast-paced visuals required in gaming and 3D modelling. The LG Ultra 13, on the other hand, provides a sharp and bright image with good color reproduction meeting the needs for general use and precision tasks like engineering and design, although, like the Vivobook, it falls short for gaming and 3D due to a less optimal refresh rate. Both laptops cater well to productivity and professional work but may not satisfy users who prioritize a gaming or 3D-oriented experience.

The LG Ultra 13 and ASUS Vivobook 15X are both only fair for gaming and AI.
The ASUS Vivobook 15X and LG Ultra 13 are fair for gaming and 3D use because they both have integrated GPUs that are capable, but not specialized for high-end gaming or 3D rendering; the ASUS has an AMD Ryzen 5 with Vega 7 graphics and the LG features an AMD Ryzen 7 with Vega 7 graphics. Both laptops have IPS screens with basic refresh rates, which are fine for casual gaming but may not satisfy demanding gamers or professionals in 3D graphics who typically require more powerful dedicated graphics cards and higher refresh rates for optimal performance.

The LG Ultra 13 and ASUS Vivobook 15X are both only fair for engineering and design.
The ASUS Vivobook 15X's processor and graphics are modest, resulting in fair performance for engineering tasks; however, it has a larger but lower quality screen compared to the LG Ultra 13, which compensates with a more powerful CPU and double the RAM, becoming beneficial for resource-intensive design software, although it offers less storage space.

"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."

Joshua Goldman | April 2017
"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
