This application provides a data switching apparatus and a data switching method, and relates to the field of communications technologies, to reduce power consumption and a delay of data switching. The data switching apparatus includes a plurality of dies, and each die includes a divider, a switching unit, a combiner, and four interfaces. An input end of the divider is coupled to a first interface, a first output end of the divider is coupled to a first input end of the switching unit, a second output end of the divider and a second input end of the switching unit are both coupled to a second interface, a first output end of the switching unit is coupled to a first input end of the combiner, a second output end of the switching unit and a second input end of the combiner are both coupled to a third interface, and an output end of the combiner is coupled to a fourth interface. A third interface of each of the plurality of dies is coupled to a third interface of another of the plurality of dies, and a second interface of each of the plurality of dies is coupled to a second interface of still another of the plurality of dies.
