Apparatus and method of dynamic load balancing for graphic processing unit

Provided are a method and an apparatus for dynamic load balancing for a graphic processing unit. A shader processor interleaves and executes vertex shader tasks and pixel shader tasks through a plurality of pipeline stages. The graphic processing unit may include at least one shader processor. The graphic processing unit allocates the vertex shader tasks and pixel shader tasks to each of the at least one shader processor. By the allocation, dynamic load balancing for the vertex shader tasks and pixel shader tasks is provided.
