As you can tell, the two cameras have the same sensor dimensions but not the same resolution. You should anticipate the Sony A7R IV to deliver greater detail with its extra 37MP. Greater resolution can also help you crop photos a bit more aggressively. The younger R3 is going to have an edge when it comes to sensor tech.
