The ASUS ROG Flow Z13 is often somewhat less expensive and more portable, suitable for users who seek mobility without compromising on powerful performance, including intensive gaming. Its combination of a touchscreen, higher refresh rate, and lighter weight makes it ideal for on-the-go use and diverse tasks. The Razer Blade 15, while often somewhat more expensive and heavier, offers a larger screen and a more potent graphics card which may be better for demanding games and 3D tasks. It may be more suited for users who prioritize gaming and performance over portability and prefer a traditional laptop form factor without the need for a touchscreen. Give Feedback

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."

"The 2022 Blade 15 offers roughly 15 to 25 percent faster graphics performance and 20 percent faster CPU performance over last year's Core i7-11800H and RTX 3080 model. Thankfully, the system doesn't need to run noticeably louder or warmer to achieve faster results, but both power consumption and battery life take a hit. The higher consumption in particular appears to be a trend amongst many 12th gen Core laptops including the Schenker Uniwill Technology GM7AG8P or MSI Vector GP66 when compared to their previous generation counterparts. We're also glad to not see below-average CPU performance which was the case for the 10th gen Core i7-10875H model."
