The pyramid at Saqqara, specifically the Step Pyramid of Djoser, is different from the pyramids at Giza primarily in that it is a step pyramid. The Step Pyramid is constructed in a series of steps, while the pyramids at Giza are smooth-sided. Additionally, the Step Pyramid was built during the Third Dynasty of the Old Kingdom, while the Giza pyramids were built later during the Fourth Dynasty.
So the correct response is: It is a step pyramid.
