Here's one I prepared earlier.
40D and 50D, processed in dcraw at defaults, no other processing.
Rerezzed to 30MP,22MP,15MP,10MP,6.7MP. Upsampling straight Lanczos.
Downsampling appropriate blur + Lanczos. No other processing applied.
Sorry for just 200x200 crops, makes it faster to view in DPR

It's actually pretty interesting (and a bit confusing :)) to see images compared at so many different output (or simulated print) sizes. To see how much the impression of noise/detail in the image depends on the 'magnification'.
