There's no public source for the claim, it's what an AMD engineer told me via private e-mail (and I don't want to publish private mails for obvious reasons).
That said, there's a "fast" path on AMD GPUs for shader code which only requires 24 bits of integer precision. Those are actually exactly enough for GameCube/Wii GPU emulation, however I'm not sure if their shader compiler properly optimizes our code to use that path.
