Image Resource have posted ISO tests (controlled) and included some straight Jpeg comparisons, also available is a compare viewer where you can view camera images side-by-side. They have also included full res NEF files to download.

Initial jpeg comparisons look better than the D7100, 12800 looks about the same as what my D7100 did at 6400.

 
I cant check by phone as you said controlled situation. Are all the exposure values same, not just ISO? Usually in IR samples they are not same.

They are all at f8 but the shutter speed is different at higher ISO's
 
Thanks for the link, the RAW file comparisons are useful. I don't understand why there are ever jpg comparisons. Reviewers seem to think that saying they use the in-camera defaults is somehow meaningful, it isn't. Since every camera uses different defaults, and you can obviously change those results, you have no idea what you are looking at, the comparison is completely meaningless. I mean if comparing point and shoots where you might rationalize that most people will just shoot default jpg, maybe that's reasonable, but if you are buying this level of camera, you probably shouldn't be shooting jpg. I mean if the default jpg from one camera saturates an image more, or has a lower contrast boost than another, but you can achieve the exact same look with another setting on the camera, what's the point in comparing two dissimilar jpg's.? A camera maker should just make their default jpg profile over saturated and excessively sharpened, and people would think from the reviews that it's amazing. The comparison of the Sony and Nikon here is a good example, so the Sony shows less noise and more smearing and less detail, what does that tell you...nothing. Can it match the Nikon if you use a lower setting for noise reduction, will the noise then be equivalent and the loss of detail gone, or will it get too noisy to bring the jpg up to the same level of detail as the Nikon? I think it's lazy on the reviewer's side. If you want to compare jpg's, take the RAW with absolutely no camera settings, and process them both the same, however you choose to process them...as long as those choices are explained, at least it's a more accurate side-by-side comparison.

When I edited some RAW images with the Nikon software, I was constantly annoyed at how many settings were applied to the images (even with the standard jpg.). There's a lot of processing that goes on. One thing I like (most of the time) with my open source software is it ignores all the picture profile stuff, all I can do with a RAW is convert from the basic file with no settings from the camera other than the White Balance. It can't read the Nikon profiles for the different jpg's, it can't apply the sharpening or noise reduction settings, etc., I have to do all that in whatever software I use. It makes a big difference seeing what the true RAW file looks like before you begin editing. In the case of the pileated woodpecker that I posted earlier, it took me a few edits with the Nikon software before I realized how much it messed up the original RAW. In the first photo I posted, the red shadows were blocked up and had no detail because of the picture profile applied, when converted from RAW to TIFF. Removing that profile showed immediately how much more fine detail there was. Anyway, this is mainly a warning for those who do shoot jpg with the camera, or those less familiar with RAW editing, make sure you know the camera and your software inside-ou (exactly what both are doing do your files in terms of processing)t, otherwiseyou are trusting one or both to make a lot of decisions about the final output, and I'd say nearly 100% of the time, someone with just average editing experience can do better with just a few seconds of editing a RAW file, usually a lot better!.

I meant as for D7100 vs D7200 having equal shutter speed and aperture at equal ISO values.

And as for Nikon software yes. View NX handles raws differently depending on camera model and you cant turn them off. In Capture NXD you can atleast turn it off.

Ah, I understand, the shutter speed is different, for example on the ISO6400 the D7200 is 1/800 and the D7100 is 1/1250. Aperture is the same though.

Note there is a large file size difference between the D7100 and D7200 jpegs. In some, an almost 50% difference with what is almost the same size sensor. That shouldn't be the case so may want to hold off on final judgment. For that reason, best to use the nef's and Nikon software to compare, IMO

That means the images got different amount of exposure/light, thus not being good for pixel peeping level ISO comparison. In that Case the D7200 got clearly more light on i'ts capture, thus giving better performance.

Wonder if the dif in light is likely the lens...notice the shots are not taken with the same focal length

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
Or the light was different. Or they used lenses with significantly different t-stop value as short prime vs zoom.

I remember someone from DPReview staff said recently thanks to same issue they make sure to give equal exposures in all recent images on new studio scene to have meaningful comparison.

I checked Exif, one is shot with 60mm and other with 70mm focal lentgh. This means zoom were used on both most likely. Can i see lens used in LR with jpeg? Or someone please check actual lenses used with Newest Capture NX-D

I ran into something similar when I tested my D7200 against my D7100 at 6400iso. Had the Sigma 17-70c on the D7200 and the Nikon 70-200VR2 on the D7100. At 6400iso F5.6 at 70mm the D7100 was 1/100 and the D7200 was 1/60. The FOVs were slightly different. Either the Sigma at 70 was shorter or the Nikon at 70 was longer or combination of both.
You can check the T stop in DXO mark site between lenses. As for different FOV, lenses have different amount of focus breathing. And that also is different depending on subject distance. If FOV is different then camera will Meter differently.

Also in any kind of semi auto mode cameras might meter differently to evaluate best exposure.

Best is to Shoot in full manual and compare exposure.

Ohh and exposure and histogram my alter a bit if different picture style/color profile is chosen.

Adobe standard for both and both in full manual might do the trick to have equal comparison.

Lets just wait for dpreview studio scene

It took them ages to get the D750 in-depth review up, so it might be a couple of months for the D7200 review to come up (hopefully not!)
 
D5500 looks very slightly better in the Comparator at high ISO or is this just more aggressive NR?

IMHO D7200 preserves more detail at 25600 ISO, however it could be my brain playing tricks on me as I just got D7200 LOL...

Both look very good for a DX format.

The D7100 was shot with the Sigma Macro 70mm f/2.8 EX DG while the D7200 was shot with the AF-S Micro Nikkor 60mm f/2.8G ED. Both serious lenses. Capture NX-D is not very dependable as it lists the Sigma as '70mm f/2.8G'. I used Exiftool to get the names.
 
Anyone use the comparometer to look at the D7200 vs D610... I think my tired eyes are playing tricks on me. It looks like the D7200 has lower noise at 12800. Maybe I'm going crazy, or clicked the wrong picture. Need more coffee...

Yes very strange i see it too!
 
Comparometer shows jpegs and jpegs have pretty different NR algorythms depending on camera. Also worth mentioning that those high iso shots are not done really in low light as you can see from very high shutterspeed and small aperture. Thats why in dpreview studio scene you have low light option to choose from.

Those are jpegs. Probably Nikon chose a stronger NR for the standard setting of the D7200. According to Bill the difference is about 2/3 of a stop: http://home.comcast.net/~NikonD70/Charts/PDR.htm#D7200,D610
