The ASUS Zenbook Duo 14 is less expensive and offers a touch screen, making it more suited for general use and light creative tasks with its dual-screen feature. Weighing less, it's easier to carry around. However, the Razer Blade 18 costs more but provides a more powerful processor, better graphics, and a larger screen with a higher resolution, better suited for intensive gaming, 3D rendering, machine learning, and engineering applications. The Razer Blade has features like hardware ray tracing and DLSS which are important for high-end gaming experiences. Give Feedback

The Razer Blade 18 is very good for general use, while the ASUS Zenbook Duo 14 is good.
The Razer Blade 18 offers superior performance with a more powerful CPU and much more RAM, as well as a larger, higher-resolution screen than the ASUS Zenbook Duo 14, but it's heavier and has a shorter battery life, making it less portable. While the Zenbook Duo 14 is very portable and has a decent battery life, its smaller screen, lower resolution, and less powerful CPU and GPU make it less suited for demanding tasks than the Razer Blade 18.

The Razer Blade 18 is very good for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14 has an integrated GPU and a screen refresh rate of 60 Hz, which are less optimal for the fast-paced visuals required in gaming and 3D applications, whereas the Razer Blade 18, with its dedicated Nvidia RTX GPU and a much higher screen refresh rate of 240 Hz, is built to deliver smoother and more immersive experiences in those demanding scenarios.

The Razer Blade 18 is excellent for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14’s combination of Intel i7 CPU, 8GB RAM, and integrated Iris Xe GPU is outperformed by the Razer Blade 18's more powerful Intel i9 CPU, 32GB RAM, and dedicated Nvidia RTX GPU, making the latter more suitable for demanding engineering and design applications. However, the Zenbook Duo's dual-screen feature and superior portability, with a lighter weight and longer battery life, offer unique advantages for multitasking and mobile use, albeit with less raw power compared to the heavier and shorter battery life Razer Blade.

The ASUS Zenbook Duo 14 offers high resolution and brightness, making it suitable for general use and detailed engineering tasks, but its moderate refresh rate might not be ideal for 3D applications that benefit from smoother visuals. The Razer Blade 18 provides a similarly crisp and vibrant display with color accuracy that appeals to engineering and design professionals who require precision in color representation. However, its lower refresh rate, while not detrimental to general use or design tasks, could detract from the immersive experience desired in 3D gaming environments.

"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"Razer made a powerful laptop in the Blade 18, showing off a beautiful and fast display and the same high-quality build we’ve come to expect from this product line. It’s also quite expensive, which is hardly a surprise, but bears repeating even in this price range. It’s pricier than the Scar 18 despite an inferior GPU and half the storage, so you really have to want the Blade 18’s design to justify the cost."
