This has the inherent flaw that it will not stream the data but load everything into RAM, meaning you will need at least 2 - 3 times the size of the files as memory, which most binary diff tools use. The only one I found that doesn't behave like this is xdelta3...

Sadly, to my knowledge, it can't. At least not the kind you'd expect. It produces VCDIFF output, which is a highly compressed binary delta. So you can just diff, patch and few the command structure. My comment was more of a "be aware that this answer will blow your main memory with a 5GB file"
