SP5 socket: CPUs, chipsets and cooler fit
SP5 is AMD's large server socket for the EPYC 9004 Genoa and EPYC 9005 Turin families. It is a land grid array socket with 6,096 contacts, and the processor package measures 72 × 75.4 mm. AMD launched it in November 2022 with Genoa, added Bergamo in 2023, and kept the same socket for Turin in 2024 with embedded Turin following in March 2025.

Overview
The socket feeds 12 channels of DDR5 ECC memory and 128 lanes of PCIe 5.0 per socket, plus 8 lanes of PCIe 3.0 for board devices and CXL 2.0 for memory expansion. That I/O budget suits dual-socket racks, storage servers, and network appliances where memory bandwidth and lane count decide throughput. Peak socket power reaches 700 W for short bursts, with production SKUs from 125 W to 500 W in this batch.
Turin keeps the socket and raises core density with Zen 5 and Zen 5c chiplets, from 8-core edge parts to 192-core dense parts. A Genoa board can take a Turin chip of the same power class after a BIOS update from the board maker, which makes SP5 a genuine upgrade path in the rack. P-suffix models stay single-socket only, while non-P models run in one-socket or two-socket boards where listed.
Processor generations
| Codename | Marketing name | Years | Notes |
|---|---|---|---|
| Genoa | EPYC 9004 series | 2022 to 2023 | Zen 4 server processors from 16 to 96 cores, launched in November 2022 on SP5 with 12-channel DDR5 and PCIe 5.0. |
| Genoa-X | EPYC 9004X series with 3D V-Cache | 2023 | Zen 4 server processors with stacked L3 to 1152 MB for HPC and simulation, including 16-core 9184X, 32-core 9384X and 96-core 9684X on SP5. Shares DDR5 and PCIe 5.0 platform with Genoa, so board support follows the maker list. |
| Bergamo | EPYC 9704 series | 2023 | Zen 4c cloud processors with up to 128 small cores on SP5, launched in June 2023 for dense scale-out racks. |
| Turin | EPYC 9005 series | 2024 to 2025 | Zen 5 and Zen 5c server processors from 8 to 192 cores, including the 15 Embedded models in this batch. Launched in October 2024 for servers and in March 2025 for embedded, on the same SP5 socket as Genoa. |
Memory layout
Each SP5 socket feeds 12 DDR5 channels with ECC RDIMM or 3DS RDIMM modules, rated to 6000 MT/s with 6400 MT/s in target configs, for up to 6 TB per socket. Twelve channels at these rates keep 96-core and 128-core parts supplied in virtualization, database and firewall mixes. Population order and maximum capacity vary by board, so the vendor memory list governs every build. Embedded designs use the same 12-channel layout with a 7-year manufacturing window and long-life firmware.
A Turin chip in a Genoa board may run memory at the older qualified speed until the vendor requalifies the board. Check the vendor list for exact DIMM speeds per BIOS before mixing generations, and match DIMM type across both sockets in a 2P build.
PCIe and CXL
SP5 exposes 128 lanes of PCIe 5.0 per socket for graphics, NVMe storage, networking and accelerators, plus 8 lanes of PCIe 3.0 for board devices. CXL 2.0 runs on four x16 links for memory expansion where the board wires it. That lane budget feeds all-flash arrays, 100-gigabit and faster networking, and timing cards without lane sharing pressure.
Lane bifurcation and CXL behavior follow board firmware, so architects confirm slot maps before committing to a storage-heavy layout. Single-socket P models keep topologies simple with no inter-socket link to tune, while dual-socket builds add Infinity Fabric between the two SP5 sockets.
Power and cooling
SP5 parts in this batch span 125 W to 500 W of default TDP, all with vendor-qualified air or liquid cooling per TDP class. The 8-core 9015 starts at 125 W while the 192-core 9965 tops the range at 500 W. Power delivery and chassis airflow must cover the chosen class, and firmware power limits can cap draw below default where a cabinet demands it, at some cost in sustained clocks.
Because P models are single-socket only, scaling out means more nodes rather than bigger nodes for those SKUs. Non-P models scale up to two sockets per board with identical part numbers in both sockets. Match the processor to the board qualified list for power class, BIOS level and heatsink kit.

Frequently asked questions
Which processors fit SP5?
EPYC 9004 Genoa and Bergamo plus EPYC 9005 Turin, including the EPYC Embedded 9005 series in this batch. Genoa covers 16 to 96 cores, Bergamo covers up to 128 small cores, and Turin covers 8 to 192 cores. SP3, SP6, SP7 and SP8 parts do not fit.
Does SP5 support two sockets?
Yes. Boards support one or two sockets, except P-suffix models which are validated for single-socket boards only. A non-P Turin or Genoa can run in a 1P or 2P board where the vendor lists it, while a 9655P or 9455P stays on 1P boards.
Do Turin CPUs work in Genoa boards?
Yes, where the board maker lists Turin support. Turin uses the same SP5 socket and packaging as Genoa, so many Genoa boards take Turin after a BIOS update. Memory speed may stay at the board qualified limit, and power delivery must cover the new TDP class.
What memory does SP5 use?
DDR5 ECC RDIMM and 3DS RDIMM in 12 channels, rated to DDR5-6000 with DDR5-6400 in target configs, for up to 6 TB per socket. The board vendor qualifies exact DIMM types, speeds and population rules.
