EPYC Genoa and EPYC Milan AMD CPUs

    Note that even EPYC Genoa (Zen 3 bases) will keep SP3 socket compatibility.

    So AMD abandoning TR4 socket is pure marketing bullshit decision, as sockets are physically same, except small wiring difference (plus SP3 has more pins used for additional memory channels and PCIe lines).

    Note that AMD revolution seems like go into a stop mode. As we'll see same cores, same SMT, same DDR4, just cache will be now shared.

    AMD states that they no longer aimed at any meaningful performance increase, but only (like Intel before) at reducing power consumption while keeping performance similar.

    EPYC Genoa will be first with some innovation. New socket, DDR5, PCIe 5.0, and most probably, famous 4 threads SMT.

    ComputerBase has shared a table with possible configurations of memory modules. From it, in particular, it follows that the new processors will support DDR5-5200, and not only in the form of peer-to-peer RDIMMs, but also four- or eight-rank LRDIMMs. However, in the latter case, when using massive 128 GB modules, the maximum memory per socket will not exceed 1.5 TB.

    The dimensions of Socket SP5 seem to be 75 × 72 mm. It is really very big. The connector will have 6096 LGA pads. For comparison, desktop socket Socket AM4 measures 40 × 40 mm. The current size for Intel Xeon server processors - LGA 4189 - has 4189 options, respectively, with dimensions of 77.6 × 56.6 mm.
