FTA: "GV100 supports up to 6 NVLink links at 25 GB/s for a total of 300 GB/s."

The math doesn't add up.

Bidirectional bandwidth.

Maybe 25 GB/s each way?

That's what I thought too, but then why would they quote unidirectional b/w in one part of the sentence, and bidirectional in the other?

Bandwidth of a single link (which is unidirectional) versus aggregate bandwidth of all links.
