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.

这个大尺寸屏幕常见于以桌面使用为主的笔记本电脑。

大尺寸可以让屏幕有更高的分辨率。因而例如字体等的细节将会更丰富。不过另一方面,小屏幕的功耗会较低,而设备也会更轻盈小巧,售价更低。

3.5 kg: 通常来说,17寸笔记本电脑的重量与此相当。这对于15寸笔记本电脑来说有些过于沉重,不过对于以桌面使用方法为设计方向的设备也可以接受。
