Reviews for the Lenovo Legion 9 18IAX10

The Fastest Gaming Laptop...sorta
Source: Hardware Canucks English
The fastest gaming laptop we've ever tested is here and its the Legion 9i which has a brand new design for 2025. With an RTX 5090 and Intel Ultra 9 275HX, we put this up to some of the best gaming laptops with AMD and Intel CPUs alongside the RTX 4090. Well it turns out that the Legion 9i is amazing in a lot of ways but it falls short in others.
