Techniques for processing pixel data are provided. The techniques include, in a first mode in which blending is enabled, reading in render target color data from a memory system; blending the render target color data with one or more fragments received from a pixel shader stage to generate blended color data; outputting the blended color data to the memory system utilizing a first amount of bandwidth; in a second mode in which blending is disabled and variable rate shading is enabled, amplifying shaded coarse fragments received from the pixel shader stage to generate fine fragments; and outputting the fine fragments to the memory system utilizing a second amount of bandwidth that is higher than the first amount of bandwidth.
