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."

Allen Ngo | May 2022
"After making a huge splash with the original 2021 model, it's expected that the 2022 refresh would be more of a minor update to an already impressive machine. It adds a higher resolution webcam (720p to 1080p), faster CPU (Ryzen 9 5900HX to Ryzen 9 6900HX), faster GPU (RTX 3070/3080 to 3070/3080 Ti), faster RAM (DDR4-3200 to DDR5-4800), faster M.2 SSD support (PCIe3 x4 to PCIe4 x4), newer WLAN module (Killer AX1690i to Qualcomm WCN685x), and a MUX switch for the new integrated Radeon 680M GPU. It's indubitably an upgrade especially in terms of single-thread processor performance."
