According to DxOMark

the Nikon D600, D610 and D750 are/were all around $2000 and have better low light iso than the 6D II, despite being much older designs.

Hi Alan

Not sure where you got your figures from. Here are the readings from DxO's SNR graphs at 3200, 6400 and 12800 ISO (db):

6D mk II: 30, 27, 24
D600: 30, 27, 22
D610: 30, 27, 24
D750: 30, 27, 24

And to add a couple more:
6D: 29, 26, 23
d850: 29, 26, 23

So in terms of signal to noise ratio, the first four cameras are essentially equal. You make the point that they are older, but the D850 has slightly more noise at higher ISO, interestingly, pretty much the same as the original 6D (I acknowledge the much higher resolution of that camera).

The Nikons are slightly better than the 6D mk II in dynamic range at high ISOs (but the difference is less than at lower ISOs, where they are measurably better), but similar to the original 6D.

There is more to hi ISO performance than these measurements. I found the biggest difference between by 6D and 5D mkII, was the substantial reduction in banding in underexposed shadows.

From the link in my post. The penultimate column "Sports" tabulates the highest iso they think suitably usable.

Hi Alan
I sense that the DXO measurements are quite robust and objective, but the derivation of their summary criteria is unclear and subjective, especially their overall score. This is why I go back to the actual measurements. Which in this case shows no real difference.
