Intel i3-4005U CPU, featuring 2 cores (4 threads) running at 1.7 GHz and integrated HD4400 graphics, delivering the realistic experience of moving and talking animals and providing fast response for every button pressed on the device

The CPU is soldered down to the board, so there are no possible upgrades here
