The ASUS ROG Flow X13 is a premium-priced laptop with a powerful AMD Ryzen 9 processor, high-end Nvidia graphics, and superior screen resolution that would excel in demanding tasks such as gaming, 3D rendering, or machine learning. However, it comes at a higher cost and has less battery life compared to the LG Ultra 13. On the other hand, the LG Ultra 13 offers a very good balance between price, performance, and battery life, making it suitable for everyday use and light engineering tasks. It's also lighter and potentially more portable than the ASUS, though less capable for intensive gaming or professional creative work. Give Feedback

Sebastian Bade | February 2021
"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."

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."
