Thunderbolt Bandwidth Testing

This video tests the maximum advertised 40GBps bandwidth of Thunderbolt and finds real-world results of more like 30GBps.  While this will NOT matter in most cases, if true, this will prevent reviewers & video analysts from recording lossless 4K60 4:4:4 via Thunderbolt.  And it could also mean limitations for people using modern video cards externally.  If you’re a fellow nerd, join me to see if I’m onto something.  And if not, that’s fine too.  Here’s affiliate links to everything I used:
