To reduce the number of draw calls Unity sends to the GPU, create a spriteA 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development.

See in Glossary atlas. A sprite atlasGraphics: A utility that packs several sprite textures tightly together within a single texture known as an atlas. More info. 2D: A texture that is composed of several smaller textures. Also referred to as a texture atlas, image sprite, sprite sheet or packed texture. More info.
See in Glossary combines multiple textures into a single texture. Unity only needs to create one draw call for all the sprites in a sprite atlas.
