Tiled renderers or "chunkers" are common on mobile because the memory bandwidth is much less (1/10th to 1/5th) than desktop GPUs. The color/depth buffers are stored in on-chip memory which is much faster. This isn't exposed to the programmer directly (Vulkan's multi pass API is related) but it has performance characteristics that we engine programmers need to be aware of.
