In which world do you get 614GiB/s memory bandwidth with an Epyc?

I think the best you can dream of is 480.0 GB/s, so 447 GiB/s.

I was going by the number of memory channels the CPU spec says it supports (12). But apparently I was wrong, as that gets bottlenecked by the number of CCDs on the chip. In which case you would need to go with a much higher end epyc processor, and then there are other limits. So much for napkin math
