First Core Duo Tablet PCs to Offer ATI X1400 Dedicated Graphics

by Reads (16,275)


As we reported earlier today, Gateway is releasing two new Tablet PC models, the 285-E and CX210. Both will offer Intel Core Duo technology and Bluetooth options. We have received further word from Gateway this afternoon and have confirmed that the new Tablet PC models will also offer ATI X1400 Mobility Radeon dedicated graphics chips as an alternative to Intel’s rather weak integrated graphics. Reports that the ATI X1400 chip handles games like Doom 3 and Quake 4 with respectable frame rates are already circulating around the web.

(view large image) mmm… How about a little snack between editing those expense reports?

If you are a Tablet PC user who plans to play games beyond “Solitaire”. It looks like the new models from Gateway will indeed provide enough graphics firepower for moderate gaming on the go. Below are the basic specifications of the ATI X1400 Mobility Radeon. For a list of the complete specs., visit the ATI website here.
