| Core | The core helps in processing graphics units. There can be multiple cores in a GPU for faster processing. |
| Memory | The GPU has its own memory to store data and perform calculations. This is separate from the system’s RAM. |
| Memory Bus | The memory bus transports data between the GPU and its memory. The width of the bus affects the speed at which data can be transferred. |
| Shader Units | These programmable processors perform the calculations of shading and texturing pixels. They are an essential component in rendering 3D images and graphics. |
| Texture Mapping Units (TMU) | TMUs are used to map textures onto 3D models. In other words, they turn polygons into detailed and textured objects that appear realistic. |
| Render Output Units (ROP) | ROPs are responsible for drawing the pixels at the final stage of rendering. They control anti-aliasing and deliver the final image to the screen. |
