For comparison purposes: an Xbox One controller next to the Steam Controller.
Both controllers share the same AB-XY button layout, but Valve's offering has a substantially larger footprint thanks to its pair of capacitive touchpads.
The rear cover snaps off with no tools required to reveal the model number: 1001.
