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."

Sascha Mölck | July 2022
"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."
