Compare camera dimensions side by side
And from DPR: The PowerShot G5 X looks like a G7 X with a grip and pentaprism bolted to the top, and to be honest, that's pretty much what it is. Except for the viewfinder and grip and a couple of other little touches the G5 X is basically the same as the G7 X: the same 20.2MP 1"-type BSI CMOS sensor, the same lens (24-100mm equiv F1.8-2.8), the same shooting features (including a selectable ND filter and Raw support). What differentiates the two cameras are the tools used to compose and control the camera.
