The ASUS ZenBook Pro Duo 15 offers a larger screen with a higher resolution and OLED technology, better for vibrant colors and contrast, ideal for creative professionals who prioritize display quality. It also has double the RAM for handling complex tasks and a more powerful processor, making it better suited for intensive engineering tasks and multitasking. However, the Razer Blade 15 is lighter and has a higher refresh rate screen, which can be more appealing to gamers who need smoother visuals. It is also more portable due to its thinner and lighter design, making it a better option for those who travel frequently or prefer a more streamlined laptop. Both laptops have the same graphics card, which is great for gaming and 3D work. If display and performance for creative workflows are your priority and you don't mind a heavier laptop, the ASUS is suitable, but if you seek a balance between performance and portability, including a better gaming experience, the Razer Blade 15 might be more appropriate.

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

Allen Ngo | March 2022
"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."
