> The PIC64-HPSC series has a built-in 240 Gbps, 16-port TSN Ethernet switch with Remote Direct Memory Access (RDMA) that uses the RDMA over Converged Ethernet (RoCE) version 2 standard

It seems like this is what the article is referencing. However, the ethernet embedded CPUs have "GigE" or even 10/100 capability. Why the need for 240 Gbps with 16 GigE ports? Are the ports 10G fiber capable and they are just future-proofing or is there something I missed with the time-slicing and RDMA?

Looks like the press release is mixing up the chip level with some board or assembly. The MPUs in the family look like 10G by themselves, so maybe the board includes the switch and shared memory.
