The AMD SP5 slot has been confirmed

It was not long before rumors of AMD’s next-generation SP6 slot were already confirmed by recently leaked photos.

In the AnandTech forums you can find photos and schematic drawings for the slot codenamed SP6. This socket has been explained in leaked slides as a platform for edge and telecommunication systems, therefore, where power optimizations are just as important as performance. According to these slides, this slot will support up to 32-core Genoa (Zen4) EPYC processors and up to 64-core Bergamo (Zen4c) series. Power will also be limited to 225 W, which is almost half of what the full SP5 socket can support.

The SP6 slot is more or less similar to the SP3 slot for the current Milan series. In fact, the size is identical (58.5 x 75.4 mm), however the SP6 has a different LGA package with 4844 contact pins. This is a significant reduction from 6096 for the SP5 socket.

  • SP3 socket – LGA 4094 -58.5 x 75.4 mm
  • SP5 socket – LGA 6096 – 76.0 x 80.0 mm
  • SP6 socket – LGA 4844 -58.5 x 75.4 mm

This is obvious, but SP6, SP5 and SP3 processors will not be compatible with each other. This also means that AMD must make two different EPYC Genoa / Torin series for each outlet.

This document sets out the requirements for a 4844-seat, 0.94 mm × 0.81 mm mid-level, Grid Surface Mount (SM-LGA) socket — hereinafter referred to as Socket SP6 — for use with the Organic AMD 4844 Position Grid Array Package (OLGA) having substrate dimensions of 58.5 mm × 75.4 mm. The Socket SP6 shown in Figure 1 is designed to provide a reliable electrical interface between the printed circuit board (PCB) and the 4844 OLGA packaging surfaces throughout the life of the product.

One of our readers suggested that the 4th generation EPYC series could now be divided into high-performance 7004 and EPYC 5004 processors with a focus on performance, which makes a lot of sense. In addition, the latter option could open up more opportunities for AMD to engage in the HEDT consumer market.
