The Razer Blade 17 is very good for general use, while the Dell Alienware m15 R7 is good.
The Dell Alienware m15 R7, with its substantial CPU and RAM, is suitable for general use and supports intense gaming, but its larger size and heavier build slightly limit portability and convenience for on-the-go users, whereas the Razer Blade 17 offers a more powerful CPU, double the RAM, and a higher resolution screen which enhances the overall experience, though its larger screen size and marginally heavier weight could pose a slight challenge for frequent travelers who prioritize compactness and lightness.

The Razer Blade 17 is excellent for engineering and design, while the Dell Alienware m15 R7 is very good.
The Dell Alienware m15 R7 is equipped with a high-end AMD CPU, ample RAM, and a powerful Nvidia GPU, which together with a high-refresh-rate screen make it a solid choice for engineering tasks; however, the Razer Blade 17 offers a superior Intel CPU, twice the RAM, a more advanced Nvidia GPU, and a higher resolution screen, thus providing even better performance for demanding engineering and design work. While both laptops offer quality displays and are capable of handling intensive tasks, the Razer Blade 17's additional power and screen fidelity come with a slight increase in weight, which may affect portability compared to the already hefty Alienware m15 R7.

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."

"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
