If you prioritize gaming or intensive tasks like 3D rendering and machine learning, the Razer Blade 15, with its more powerful GPU, is a better choice; however, it's typically more expensive than the ASUS ROG Flow X16. The ASUS has a slightly larger and better quality screen, which is also a touchscreen with a higher battery capacity, making it great for general use and some engineering tasks. Although the Razer Blade has a slightly smaller and less color-accurate screen, it compensates with a higher refresh rate, which can be an advantage for fast-paced gaming. Both are similar in terms of portability, but the Blade is slightly lighter. Give Feedback

Christian Hintze | June 2023
"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average performance."

"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."
