Very impressive if it's with no noise reduction.
Is it from a RAW or JPEG? Any NR applied at all?

Here is a crop from a JPEG direct from my K20D.
ISO1600 highest quality JPEG without any noise reduction (turned off in custom menu).
I used the lossless crop option in Irfanview to crop the image without quality loss.
I find the K20D allready very good in the noise department. The deciding factor will be how the two camera's perform in low light/high iso performance. Both the K-7 picture above and my K20D picture were shot in daylight which allready reduces the amount of noise. (less light hitting the sensor = more noise)
But side by side the K-7 has the edge on noise control in my opinion but we don't know which settings were used on the K-7.

same shot as above but with noise reduction set to "weak" (level 3 in the custom settings for high iso noise reduction)

Mike could you simply make a link please to the photo the PU site is then a bit more easier to navigate. Also turn the photo will you
The noise looks weaker, certainly the coloured noise so if this real without NR it ould be great. I wander how it is with iso3200, it might pull it off.

I think it would also be worth while to see with ISO 100, 20 and/or 400 to compare how much detail is lost with the noise reduction.
