When choosing between the ASUS ROG Flow X13 and ASUS ROG Strix G18, consider that the Flow X13 offers more portability due to its smaller size and likely longer battery life, making it suitable for on-the-go use and everyday tasks, while the Strix G18, being larger, usually provides better cooling and therefore higher performance for demanding applications like gaming, 3D rendering, or intensive engineering software. However, the Strix G18's size and power may mean it's heavier and has a shorter battery life, which could be inconvenient if you need to move around frequently or work away from power outlets for extended periods.

The ASUS ROG Strix G18 (2024) is excellent for engineering and design, while the ASUS ROG Flow X13 is very good.
The ASUS ROG Flow X13, while still powerful, offers less raw performance than the ASUS ROG Strix G18 due to the latter's more robust CPU, RAM, and GPU, crucial for demanding engineering tasks; however, the Flow X13's greater portability and adequate screen quality make it a good choice for those who prioritize mobility and still require competence in running design software. The Strix G18, with its superior screen and performance, excels for intensive engineering work but sacrifices portability and is best suited for a stationary setup where its heavier weight and larger size are less of a concern.

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."
