Its mostly an experimental platform, never intended for production, to shake out issues that we'll see when next generation platforms show up with DDR5 and PCIe Gen5. With a current single-socket setup we'd be limited by memory bandwidth around 500Gb/s or so, but 800Gb/s should hopefully be within reach from a single socket with DDR5 based servers. Especially since the limiting factor now is the traffic on the xGMI links between the sockets is unbalanced.
