CPU/Chipset MPS of >=512

Hello All,

I am currently working a project that needs a good amount of PCIe throughput (with minimal overhead).

I am trying to look for a CPU/Chipset that can support a PCIe max payload size >=512B, but I can't find one?

Does anyone know of a Chipset/CPU that can support such a payload?

I checked the Xeon, i5, i7, and x99, x58 documentation but they all say 128B or 256B. Any ideas.

Regards,

Michael Riera
