The Dell Alienware m15 R7 is built more for gaming and high-performance tasks with its more powerful processor and dedicated graphics card, which make it suitable for intensive tasks like gaming, 3D modeling, and machine learning. It also offers a larger and faster display, but is heavier and could have a shorter battery life, making it less portable than the Razer Book 13. On the other hand, the Razer Book 13 is more affordable, offers adequate performance for everyday tasks and even professional work with its efficient processor and integrated graphics, and is lighter and likely has a longer battery life for better portability. If you prioritize high performance for demanding applications and can accommodate a less portable device, the Alienware could be the right choice, however, if you prefer a balance between performance, cost, and portability for general use, the Razer Book 13 may be more suitable.

The Dell Alienware m15 R7 is very good for engineering and design, while the Razer Book 13 is good.
The Dell Alienware m15 R7 excels in engineering and design because it features a powerful AMD Ryzen 9 processor and Nvidia RTX 3070 Ti graphics card, which is superior for computing and visual performance; the screen quality is very good though not as bright as the Razer's. The Razer Book 13, while good for engineering and design, hinges on its portability and high-resolution touchscreen, but falls short with a less powerful Intel i7 processor and integrated graphics, making it less suited for heavy-duty engineering tasks compared to the Dell.

Tom's Hardware
Brandon Hill | October 2022
"The Alienware M15 offers solid gaming and leading endurance. It makes the most of its CPU and GPU while delivering stellar battery life for a gaming laptop. Opening the lid presents a full-size keyboard with honeycomb cutouts above it on the deck. An oblong RBG lightning element surrounds the entire rear panel and can be color-synced with the other lights on the laptop. There’s not a lot to dislike about the M15 Its productivity performance lagged in some areas, particularly in the storage benchmark, and it’s a bit heavy. Alienware has a clear winner here with the M15 based on its strong overall performance and endurance."

"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."
