It can batch together quite large amount of geometry vertices, but it can set the material only once per batch. If you have two material assets that are identical apart from their textures, you can combine the textures into a single, larger texture. This costs more memory and bandwidth than instancing, but it can combine multiple different source meshes into a single call, as long as they're small and all use the same material. When that happens, Unity can then merge the different meshes into a single chunk that uses the common material. GPU Instancing : 35 set passes / 600+ draw calls .
