Socket SP6 (LGA 4844) is a zero insertion force land grid array CPU socket designed by AMD supporting its Zen 4c-based Siena Epyc server processors that launched on September 18, 2023.
It is designed for server systems targeting infrastructure and edge computing segments.
[1][2] In November 2022, AMD launched the SP5 socket alongside its Epyc 9004 series of processors, codenamed Genoa.
The large physical socket and thermal footprint excluded SP5 from certain edge applications.
Socket SP6 serves segments of the server market where performance is not a priority, but cost, value, small footprint, and low power consumption / heat dissipation are.
