Shaders. He is talking about "custom shaders" interface. It allows to execute only single shader (but you can chain them) with input = previous output and without ability to change resolution. Those limitations is the problem, not HW.
Shiandow's deband runs in several passes: first n passes downscale image by a factor of 2 each, last one uses all of downscaled images as input (or last n passes, each using n-th image, dunno).
