I already made a comment about Apple's GPU here: https://news.ycombinator.com/item?id=14021814

Apple actually has its own mobile GPU, built from scratch.

The Tile-Based Deferred Rendering GPU is an advantage from the GPU sharing the same memory with the GPU. On a normal desktop GPU you need to transfer huge amounts of data from the main CPU RAM to the Video Ram but on a mobile device, the CPU and the GPU sit both on the same memory system. This allows you to architecture your GPU in a different way.

Both ARM's Mali and Qualcomm's Adreno use Tile-Based Deferred Rendering.

Both Nvidia and AMD have already switched or are moving towards tile based rendered to reduce bandwidth (and hence energy) costs.

Source? That's a huge architectural change for them.

So that's tile based rasterization not tile based rendering. There's a huge difference. This is basically just a cache before the ROPs write into DRAM.

EDIT: Also, I don't think his test is proving what he thinks it is.
