The Razer Blade 15 is costlier and offers better performance for intensive engineering tasks, 3D rendering, machine learning, and gaming. It comes with a powerful GPU and a high refresh rate display, which is great for fast-paced games and graphics-heavy applications but has shorter battery life and is heavier, affecting portability. In contrast, the Razer Book 13 is less expensive, lighter, and has a longer battery life, making it more portable for general use, but its integrated graphics are less suitable for demanding tasks and gaming. Its touchscreen and 16:10 aspect ratio screen are beneficial for productivity tasks, and it's also more compact due to its smaller screen size. Give Feedback

The Razer Blade 15 is very good for engineering and design, while the Razer Book 13 is good.
The Razer Blade 15 stands out for engineering and design tasks with its more powerful CPU, higher-end dedicated GPU, and larger, high-refresh-rate screen with good color accuracy, leading to robust performance for computational and graphical workloads. In contrast, the smaller and lighter Razer Book 13, while still good for engineering and design due to its capable CPU and good screen quality, forgoes dedicated graphics for integrated ones and offers more portability but less power for intensive tasks.

The Razer Blade 15 has a better screen than the Razer Book 13 for general use, gaming and AI, engineering and design, and content creation.
The Razer Blade 15's excellent screen quality for general use and engineering stems from its high resolution and brightness, which make images sharp and colors vivid, along with a wide color gamut, essential for precise design work. However, its lower refresh rate can be a drawback for gaming, where fast-moving visuals may not appear as smooth. On the other hand, the Razer Book 13 also offers a good display for daily tasks and professional work with similar traits, but still lacks in the high refresh rate department needed for optimal gaming and 3D experiences.

The Razer Blade 15 and Razer Book 13 are both good for general use.
The Razer Blade 15 offers solid performance for general use with its higher-end CPU and dedicated graphics card, which is good for demanding applications, but it's less portable and has shorter battery life compared to the Razer Book 13, which provides sufficient performance for everyday tasks, is more portable due to its smaller size and lighter weight, and has longer battery life making it ideal for on-the-go use. Both have high-quality screens and the same amount of RAM, ensuring smooth multitasking, but the Book 13's higher portability and longer battery life may appeal more to those who prioritize mobility and extended use without charging.

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."

"The Razer Book is like an XPS 13, but faster. The Book 13 combines the design philosophy and performance of a Blade Stealth with the 16:10 display of a Dell XPS 13 for an impressive piece of hardware. Office users who want something more stylish than the typical Dell, HP or Lenovo will certainly find themselves drawn to this Razer subnotebook. If your priorities are to have the best-looking and fastest 13-inch laptop in the office over auxiliary features, however, then the Book 13 proudly fulfills that niche."
