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.

89.1% Legion 9 18IAX10 review: Lenovo's first 18-inch gaming laptop is almost a home run | Notebookcheck
Despite being a bit late to the 18-inch gaming ring, the Lenovo Legion 9 18 is easily one of the best in its size category even when up against seasoned models like the MSI Titan or Razer Blade 18.

In 2011, it acquired a majority stake in Medion AG, a European computer hardware manufacturer. In 2014, Motorola Mobility was purchased, which gave Lenovo a boost in the smartphone market.

3.5 kg:

A laptop with this weight is comparatively heavy and less designed for mobility than for use at the desk. Therefore, the devices tend to shine less with battery life than with a large screen and higher performance.

3.532 kg:

Only a few laptops are in this weight class because the mobility is rather limited due to the high weight.

89.1%: There are not very many models that are rated better. Most of the assessments are in percentage ranges below that. The tested product is not considered perfect, but the sources give a clear purchase recommendation.
