Graphics processing unit, vertex processing method thereof and terminal equipment

The invention provides a graphic processing unit, a vertex processing method thereof and terminal equipment, and the graphic processing unit comprises a plurality of arithmetic units which are used for processing a to-be-displayed graph to obtain processed vertexes; the vertex collection unit is used for collecting vertex data output by each operation unit according to a task segmentation sequence; each arithmetic unit is provided with a label cache used for caching the identifier of the output vertex, for each processed vertex, the arithmetic unit judges whether the vertex hits in the label cache, if the vertex hits, compressed vertex data is output, and if the vertex hits, the compressed vertex data is output. The compressed vertex data comprises identifiers of the vertexes and/or storage positions of vertex data contents corresponding to the vertexes in the vertex collection unit. According to the technical scheme, the transmission bandwidth of the vertex data in the graphic processing unit can be reduced,
