It's probably more along the lines of the same data being processed within the same chip. Not actual memory bandwidth. This HPU they are talking about is processing depth information and eye lines (probably quite a bit more often than 60hz), it's quite possible they are processing the same data multiple times over achieving theoretical bandwidth in the TBs. It's disingenuous sure but it's like saying a network with 20 100GB routers can handle terabytes of data.
