Canon 50D noise vs 400D.

Not a very scientific test here.
I took one 30 second dark frame on the 400D @ 1600ISO RAW and the same on the 50D @ RAW, SRAW1 and SRAW2.
Here are the results after running them through the Canon DPP program, adjusting the exposure up to full and the top curves to 100 brightness, 87 contrast to show the noise. I then reduced the file size in saving, (which did affect the images a small amount by introduced blotches in the 50D shots).
