Florian Glaser | March 2023
"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."

Allen Ngo | May 2022
"The Alienware x17 R2 recognizes targets a significantly higher TGP of 175 W for a roughly 30 percent performance boost over laptops running on the ~100 W GeForce RTX 3080 Ti like the Razer Blade 15 or Gigabyte Aero YE5. Similar results can be found through the CPU as well. This single aspect of the Alienware is perhaps the biggest differentiating factor between it and other ultrathin gaming laptops. Of course, the "performance at all cost" approach comes with drawbacks. Power consumption in particular is through the roof and battery life suffers because of it even when on the lowest performance settings."
