Ill have to redo the 5Diii Chart because it was a little out of focus, but this is the ISO Noise Comparison Chart for the Sony a7s vs the Panasonic GH4 , All images are f 5.0, bumping up ISO by one stop increments. The A7s will go down to ISO 50 as well.

Important to note that the GH4’s images were resized to the 12MB equivalent of the A7s viewed at 100%. I personally see at minimum a 2 stop noise advantage (maybe more) in favor of the A7s on ISOs over 3200.
