The K20D may well display less noise at low ISO as well, but noise isn't really a factor in this range. If you don't see it, it isn't worth worrying about. I can say for sure that the K20D is less noisy than the K10D at ISO 400. At ISO 200, I can't recall having ever noticed noise with either camera.
