Fast mobile shaders or rather Mobile! Fast!

Saving BW & ALU•Framebuffer writes• Tiled & Tiled Deferred: great!• Classic: not so much•ALU & Texturing per fragment• Deferred will save on all hiddenfragments• Early Z-Cull saves on coarse blocks• Depends on submission orderTBDR and Tiled architectures process the screen in tiles. While a tile is processed, theframebuffer and depth buffer data is kept in an on-chip fast memory. This saves a lot ofbandwidth (and consequently energy), however it has downsides as well (tiling process is notfree, etc.).
