6D vs 70D High ISO performance comparison

Cool, thanks! Here are the 2 side by side making the differences more pronounced. Then equalized....

Cool, I should have done split image samples too.

Here is a quick and dirty NR process.
The exact same action was applied for both cameras' ISO6400 RAW shot, in ACR. So even after NR, the initially better camera wins.
Of course, obviously we should approach the 70D and 6D differently when it comes to processing the images, but the bottom line is that even after doing your best at processing both, the difference will remain. It's just physically impossible to bring 70D noise levels down to 6D levels AND still preserve the same amount of detail. One or the other will suffer when you try to do that.

I probably could/should have left in more detail but this was just a quick NR.

70D left, 6D right. 100% crops.

And finally, here is the already posted ISO6400 SOOC jpeg in a split way. NR Standard

The tools make a huge difference in results, and even though the canon JPG engine is much improved, it still removes a ton of detail and they run very aggressive NR values with the latest bodies.

If you are willing to share the 70D and 6D raw images, I can do my usual comparisons between them and post the results here in this thread. I will also run my custom noise actions to see how well they clean up while keeping details.

This time - real 100% no-NR including premium chroma noise

70D ISO 6400

same RAW NR values..

70D RAW quick NR

^^^ now these are good examples, thank you Lukas.

Definitely! That is more in line for what I would expect.

The next test should be a mix of colors (like Gabe's), because the different color channels will produce more noise than others. The red channel produces alot of dirty luminescent noise, the green is very clean needing just a moderate amount of normal NR, and the blue produces splotchy smeared noise, for example (each model has slightly different characteristics, but this is a good general description).

Something like a color-rite card would be great to show this. Or print this and use it just for an ISO checker (won't be sharp, but that is okay).

Ok, thanks for the clarification. I will compare my best processed 60D to SOOC from my 6D at 6400. Interesting proposition. Although I must admit, if I know I'm going to that extreme, I'm taking the 6D. I always shoot raw.

Man, I am out of my league here. You guys are pros!
