Andreas Osthoff | March 2022
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."

"Dell's Alienware m18 delivers on its promises: This is a large, powerful gaming laptop with the premium flair and feel you expect from an expensive purchase. The drawbacks are really the price and battery life, which in context are reasonable. (We'd also like to see more ports on the laptop's sides.) This price tier exists for deep-pocketed enthusiasts, and if you’re considering anything in this range, the m18 isn’t an outlier. For the majority of shoppers, of course, all of these mighty 18-inch systems are likely too expensive."
