A graphics-processing method and a graphics-processing apparatus are provided. The graphics-processing method includes the steps of computing a vertex position of a vertex in a binning phase to obtain a first position data; generating a first signal according to a first condition, wherein when the first signal corresponds to a first value, the first position data is stored into a memory unit, and when the first signal corresponds to a second value, the vertex position of the vertex in a rendering phase is computed to obtain a second position data; computing a vertex varying of the vertex in the binning phase or the rendering phase; and rendering in the rendering phase according to either the first position data or the second position data.
