>>112645 They have about the same noise, just different noise-reduction algorithms. The EOS400D examples look a little sharper, the D80 examples look a little less noisy. The D80 smears the noise around a bit to make it less noticeable, the EOS400D compromises between preserving fine details and noise, and the A100 prioritizes details and lets the noise fall where they may.
If you read the description of the tests, those were all examples of the out-of-the-camera JPEG. If they were processed RAWs with the same processing software, they'd look a lot closer.
In fact, from the page where you got that image: >As you can see there is no discernable difference between the EOS 400D, D80 and DSLR-A100 up to ISO 400 (except for slightly better sharpness from the EOS 400D image). The EOS 400D continues this sharp detail all the way up to ISO 1600 but does have noticeably more chroma noise than the D80 which employs better chroma noise reduction. At higher sensitivities the EOS 400D delivers more detail but with slightly more chroma noise, the D80 less detail but a cleaner more 'film like' appearance to noise grain, the DSLR-A100 has the noisiest image although has good detail at ISO 800.
