The point is that the more photons you capture, the less noise you get.
Assuming the Foveon wastes the same percentage of its area on interconnect
as a Bayer pattern chip, the Bayer chip will filter out all the "wrong"
color photons that hit each sensor, while the Foveon will actually use them.

Obviously, implementation matters. But I see no reason to expect that a
Bayer pattern chip is intrinsically better--it's just been worked on longer.
