The ASUS ROG Flow X13 offers a balance between portability and performance with its smaller, lighter design and touchscreen, making it well-suited for general use and mobile professionals who value a more compact machine. In contrast, the ASUS ROG Strix G18 is larger with a stronger emphasis on gaming and engineering tasks due to its bigger screen and higher refresh rate, as well as superior performance scores in 3D, machine learning, and engineering applications. If battery life is a concern, both laptops offer respectable durations, but keep in mind that the greater weight of the Strix G18 makes it less convenient for frequent travel. 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."

"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."
