A graphics processing system that includes a graphic processing circuit and an enhanced memory circuit is presented. The graphics processing circuit performs the rendering of graphics primitives to produce pixel fragment data. The pixel fragment data is then grouped into fragment blocks that are compressed and sent across a bus of limited bandwidth in an efficient manner to the enhanced memory circuit. Within the enhanced memory circuit, the compressed fragment blocks are decompressed and restored to their original state. Comparison and blending operations are then performed on a block-by-block basis with pixel data stored in the frame buffer.
