Rome SoCs support both single and 2-way multiprocessing with up to a maximum of 64 cores (and 128 threads) per processor for a total of up to 128 cores (and 256 threads) for a 2-way MP system. Those SoCs support 128 PCIe lanes each, however, half of them are lost when in 2-way MP (leaving the system with the same overall lanes count as a single socket solution). Communication between the two chips is done via AMD's {{amd|Infinity Fabric}} protocol over the 64 reserved lanes. Rome is backwards platform/socket compatible with Naples and forward-compatible with Milan. |
