Socket SP6 (LGA 4844) is a
zero insertion force
Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little (but not literally zero) force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is m ...

History
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 was created as a smaller variant of socket SP5 with fewer pins and less memory support, reducing the footprint from 72×75.4 mm to 58.5×75.4 mm, identical to that of SP3.
The SP6 platform comes in at a lower cost than the SP5 platform's Genoa and Bergamo server processors.
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. Examples of this are infrastructure computing and edge computing. Currently, it only supports Epyc 8004 processors, codenamed "Siena".
It supports processor TDPs up to 225 W.
On October 19, 2023, AMD announced Threadripper 7000 high-end desktop and workstation processors, utilizing the
sTR5 socket, which is physically identical to the SP6 socket, but not electrically compatible.
Threadripper 7000 processors were launched on November 21.
