The ASUS Zenbook Duo 14 is less expensive and offers good portability with a decent battery life suitable for general use and multitasking thanks to its dual-screen design. It's also lighter, making it easier to carry around. On the other hand, the Razer Blade 15, while more expensive, provides superior performance for 3D rendering, machine learning, and engineering tasks due to its high-end processor and graphics card. This makes it ideal for gaming and intensive tasks, but it comes at the cost of battery life and it is heavier, which impacts portability. Both have high-quality builds and multiple ports for connectivity. Give Feedback

The Razer Blade 15 and ASUS Zenbook Duo 14 are both good for general use, though the Razer Blade 15 is somewhat better.
The ASUS Zenbook Duo 14 is deemed fair for general use because it comes with less RAM, a lower capacity battery, and a less powerful CPU compared to the Razer Blade 15, which offers a more powerful CPU, double the RAM, and better screen quality, making it good for general use. Additionally, the Blade 15 has superior storage capacity and takes the edge in portability despite being slightly heavier, as it also has a longer battery life, which is quite important for general use scenarios.

The Razer Blade 15 is very good for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The Razer Blade 15 excels in gaming and 3D tasks primarily due to its high-end Nvidia RTX 3070 Ti graphics card and a screen with a very high refresh rate, which are both very important for these purposes. In contrast, the ASUS Zenbook Duo 14 has a less powerful integrated GPU and a lower screen refresh rate, making it only fair for such tasks despite its good screen quality and competent CPU.

The Razer Blade 15 is very good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The Razer Blade 15 stands out for engineering and design due to its more powerful Intel i7 processor, double the RAM, and superior Nvidia RTX GPU, delivering better performance for graphics-intensive tasks, along with a higher-quality screen with greater resolution and color accuracy. While the ASUS Zenbook Duo 14 offers a commendable dual-screen workspace and satisfactory performance for design applications with a capable CPU and integrated GPU, it lags behind the Razer in raw power and screen quality, yet it might be preferred for its lighter weight and longer battery life for on-the-go usage.

The Razer Blade 15 has a better screen than the ASUS Zenbook Duo 14 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, both the ASUS Zenbook Duo 14 and the Razer Blade 15 provide crisp and vivid displays due to their high resolutions and brightness, though the ASUS has an advantage with an additional secondary screen for multitasking. In engineering and design, the Razer stands out with a wider color gamut coverage including DCI-P3 and Adobe RGB, which is crucial for color accuracy in professional work. However, for gaming and 3D applications, neither laptop excels due to their lower refresh rates, leading to less fluid motion compared to laptops specifically designed for these tasks.

Allen Ngo | May 2020
"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."

"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."
