That looks pretty close to the 7D, the noise is a bit more fine perhaps. I wonder what I can do with this using my noise actions... 
It does look like you have sharpening set on the raw, you should take that down to 1, especially at 6400 with NR sliders down.
Just a quick run using the steps I had last used with the IR files. Resized down a bit to get more material in the frame.
