Hot Hardware published a review on the ASUS Zephyrus With GeForce GTX 1080 Max-Q Gaming Laptop Preview: Thin And Beastly

A quote from the article:

NVIDIA's Computex 2017 unveiling of the new GeForce GTX with Max-Q Design technology for laptops was presented with the usual charismatic polish and enthusiasm that the company's leather-clad CEO, Jen-Hsun Huang is well known for. Frankly, it seemed a little too good to be true. In one hand, Huang held a legacy 10-pound boat anchor of a gaming notebook, while in the other he held the new ASUS ROG Zephyrus, a sub-5 pound machine that's just 17.9mm thick.

Extolling the virtues of the new ASUS notebook powered by a GeForce GTX 1080 with Max-Q Design technology, he pointed out that the new machine had 3 times the gaming performance of the old one (powered by a mobile GeForce GTX 880) at half the weight and 1/3rd the thickness. It was a stark contrast to be sure, and a bold claim, and you know we're the type to put bold claims to the test...
