The ASUS ROG Flow X13 is a premium, highly portable device with a smaller screen, higher resolution, and a touch-enabled, brighter display, making it suitable for general use and on-the-go productivity. It has a better battery life, and its performance is well-suited for engineering tasks and 3D/machine learning. In comparison, the ASUS ROG Strix G15 offers good gaming performance with a larger screen but lower resolution and without touch capabilities. It's less expensive and heavier, so less portable, and has a shorter battery life. The Strix G15 could provide satisfactory general performance but won't match the Flow X13's screen quality or portability. 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."

"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
