Κ7 And K20D Test Shot.

Ok I think there is a problem because i don't think the K20D has better detail than the K7 it should be at most the same, so something must be wrong with the K7, I don't have the K20D anymore but have pictures from like a couple months ago and today took the same picture with the K7 just to compare, I am bummed because i don't know what it could be, anybody have any clues? Both shot at ISO 1600 DA 17-70 @f4.

The K7's picture clearly shows effects of noise removal. If you're shooting JPEG, you might want to check your settings (Custom Settings, there should be noise removal somewhere)

On top of what Nanthiel wrote you should take into account, that the K20 images is much darker, thus giving the grphic lines of the lighter more visual weight/impact. That does not necessarily mean, it really contains more detail, it just apperas sharper and more detailed to the eye.

K7 And K20D Test Shot

This is the same effect I used to get with another brand, when the metering was set to spot, with the likes of a "non-focus" area where the spot hit. Just for fun, I would suggest taking it again, and change the metering, or, otherwise making sure the meter focused at the top edge of the picture frame. May sound a little odd - but ya never know.

Well I had the K7 NR set to strongest so that was my problem, but just to ask on your K7 where do you have the NR set to?

If I intended to use the JPEG straight off the camera, the best balance between preserving detail and noise reduction at ISO3200 seems to be "Medium" NR.
The noise at ISO1600 is well controlled, and "Weak" NR is quite good enough.

For a RAW shot or PP the JPEG through Noise Ninja, for example, I just leave NR Off. There's plenty you can tweak off the camera with the RAW file.

Not a good target....

I don't think the representation here is indicative of the performance at ISO 1600 of either camera. I can't speak for the K7 but my K20D turns out better ISO 6400 than that shot at 1600. Something is not right here, maybe the settings, maybe the reflections and metering, maybe the light, but it is not at all typical of what I see with my K20D...not even close!
I'm not questioning your results or your displeasure, but I think you may need to re shoot a few more subjects under varying conditions to reach any conclusions that will guide your judgment as to the IQ of higher ISO shots.
