The ASUS ROG Flow X13 offers high performance especially for 3D tasks, machine learning, and demanding engineering software because of its superior GPU and processor; it's suitable for gaming too. However, it's more expensive and less portable compared to the LG Ultra 16, which still provides good performance but is better for general use and has longer battery life – ideal for those on-the-go or who prioritize less weight and a fanless design. The ASUS has a smaller but higher-quality touchscreen display with better refresh rate and color accuracy, while the LG has a larger non-touchscreen display at a standard refresh rate. Both have backlit keyboards and Windows 11 Home, but only the ASUS has hardware ray tracing and DLSS for advanced graphics tasks. Give Feedback

The ASUS ROG Flow X13 has a better screen than the LG Ultra 16 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 excels in screen quality for general use and engineering due to its high resolution and brightness, coupled with strong color accuracy, providing clear and vivid images necessary for detailed work. However, its lower refresh rate makes it less suitable for gaming and 3D applications, where smoother motion representation is critical. The LG Ultra 16, with moderate resolution and brightness, offers adequate screen quality for everyday tasks and engineering, but it also falls short in gaming and 3D performance due to a less optimal refresh rate and color gamut.

How the ASUS ROG Flow X13 and the LG Ultra 16 compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"Unlike the gram, the Ultra PC isn't designed to be as lightweight as possible. The 16-inch laptop is a whole 400 g (0.88 lb) heavier than its 16-inch gram counterpart partly because its chassis is not made of magnesium. Other than that, the Ultra PC seems like a copy of the gram – but with longer battery life, lower noise levels, and a clean, delicate look."
