The entire SP5 socket has a height of 7.5 cm and a 7.2 cm width for the new generation of Zen4 for data centers. The EPYC 7004 series under the code name "Genoa" will have up to 96 cores, and Bergamo with Zen4C kernels - up to 128 cores. Both series must be supported by the same SP5 connector.
The first photographs of the next generation EPYC motherboard were posted on the ServeThehome forums. The design of the socket corresponds to the charts who leaked as a result of last year's hacking Gigabyte. In addition, we see the 12-channel DDR5 memory, which is a new feature of the Zen4 EPYC series. In the circuit board schemes, it can be seen that each of the four SP5 connector segments is connected to one of the subchannels of each of the 12 DIMM modules.
At the previously leaking diagrams, a complex mechanism for fixing and holding for large SP5 processors is shown. At the moment it is unclear whether we will see SP5 SP5 Socket for the AMD Hedt Threadripper series.
Genoa processors should have up to 96 cores and 192 streams. They are based on TSMC N5 technical process and have a Zen4 microarchitecture. AMD has not yet confirmed whether they are planning a series of EPYC 7004 with 3D V-Cache, as well as the "Milan-X" series released last year.
According to AMD, Genoa is currently coming to the first customers and is preparing for launch by the end of 2022. The Genoa and Bergamo series should be the first to use SP5 sockets, and by rumors, the Turin series is expected soon next year.
