IGN
Samuel Horti | June 2023
"The Predator Helios 16 stacks up well against its closest competition in benchmark comparisons. The Acer Predator Helios 16 isn't perfect. It's bulky, its lid feels flimsy and some of its keys are just too damned small – but none of its problems are fatal, and it shines where it counts. The powerful graphics and processor combo are spot on for this price point, the fans stop it getting hot under pressure, and the display is as good as you’ll find under $2,500. It's simply one of the best laptops to play demanding games on."

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."
