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."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
