AMD EPYC 7402P socket: SP3
The AMD EPYC 7402P uses SP3, the LGA socket for EPYC server processors. The 24-core chip at 180 W runs single socket only.

What the EPYC 7402P is
The EPYC 7402P is a 24-core, 48-thread server processor from Rome. It launched in August 2019 for dense single socket nodes with a 2.8 GHz base and up to 3.35 GHz boost at 180 W. Four chiplets share 128 MB of L3 across the package.
The high 2.8 GHz base for a 24-core part keeps per thread performance strong in mixed VM fleets. Twelve megabytes of L2 back compilation threads. The 180 W envelope suits 1U and 2U single socket chassis with high airflow.
Single socket validation cuts platform cost per core for cloud builders. The non-P 7402 serves dual socket clusters with identical clocks. Twenty four cores hit the sweet spot between license cost and density.
Socket and motherboard compatibility
The EPYC 7402P fits SP3 on single socket boards with server power delivery. Exact SKU listing decides qualification. Rome era boards post it natively.
Dense single socket designs pack 24 cores with a full NVMe cage in 1U. Power and thermal budgets follow the board manual. The How to find your CPU socket type guide maps generations to platforms.
Later Milan BIOS updates extended many 7402P boards to newer SKUs without hardware changes.
Memory, PCIe and cooling
Eight channels of DDR4-3200 ECC feed 48 threads at up to 204.8 GB per sec. Two DIMMs per channel reach multi terabyte capacity per socket. Population order follows the manual.
PCIe Gen4 lanes total 128 for accelerators, NICs and NVMe. Dense nodes split lanes across risers for GPU and storage mixes. Retimers help long traces at Gen4 speeds.
The 180 W class needs high flow heatsinks with front to back air. Paste service follows the multi die pattern. Altitude and inlet heat derate boost.
Where this Rome part fits
Twenty four cores suit virtualization hosts past fifty VMs and mid size databases. Base clocks near 3 GHz keep tail latency low under load. The 128 MB L3 absorbs working sets that spill on smaller caches.
Single socket clouds and rendering nodes fit here with 512 GB to 1 TB of RAM. All channels filled matters for bandwidth bound rendering. The AMD EPYC 7402 twin covers dual socket scale out.
Buyers confirm board firmware and power delivery before ordering dense configurations.
Upgrade paths
On SP3 growth runs to 32-core 7502P and 64-core 7702P single socket parts where validated. Milan P SKUs follow with vendor BIOS support.
Newer SP5 servers bring DDR5 density for the next refresh. The CPU cooler compatibility by socket guide covers heatsink classes across TDP bands.
