What does this mean? The article says 'TB' which would be terabytes. Terabytes are made out of gigabytes. There is nothing faster than straight memory bandwidth. DDR5 has 64 GB/s max. 12 channels of that is 768 GB/s.
Terabytes per second is going to take multiple computers, but it will be a lot less computers if you're using shared memory bandwidth and not some sort of networking loopback.
