AMD EPYC 8324P socket: SP6

What the EPYC 8324P is

The EPYC 8324P is the 32-core single socket Siena server part for SP6 in September 2023. Thirty-two Zen 4c small cores with multithreading run at 2.65 GHz base and up to 3.0 GHz boost with matching all-core boost, backed by 32 MB of L2 and 128 MB of L3. The TSMC 5 nm package targets 180 W inside a 155 to 225 W window for efficient data-centre and edge racks. It leads Siena density below 64-core parts with balanced clocks.

Efficient threads with server IO suit cloud edge, storage and virtual desktops that need many vCPUs without Genoa power. Thirty-two cores share 128 MB of L3 for locality, while 6 DDR5-4800 ECC channels feed data at lower board cost than 12-channel platforms. Ninety-six Gen5 lanes serve networking and NVMe for single-socket nodes. Power stays well below 360 W flagships for dense racks.

Buyers compare the 8324P against Xeon Gold density parts where performance per watt decides. Siena wins single-socket efficiency with 6 channels, while Genoa wins where 12 channels matter. Boards built for SP6 accept the full Siena stack with a BIOS update. The Socket vs chipset: what decides whether a CPU works guide is secondary to SP6 board lists.

Socket and motherboard compatibility

The 8324P fits SP6 on single socket server boards with LGA 4844 frames. Siena is 1P-only, so dual socket pairing is not supported. Board lists must name Siena 8004 for Zen 4c support. Power delivery for 180 W continuous with wide cTDP suits 1U and short-depth chassis.

SP6 boards wire 6 DDR5 channels with one DIMM per channel for best speed in many layouts. BMC firmware covers fleet management. Confirm heatsink height and airflow for dense 32-core nodes.

Memory, PCIe and cooling

DDR5-4800 ECC RDIMM in 6 channels feeds 32 small cores for edge clouds. Capacity scales with large DIMMs for storage nodes. ECC stays enabled for uptime. Validated kits at rated speed are required.

PCIe Gen5 gives 96 lanes in single socket plus CXL for networking and NVMe. A 32-core node typically wires 25 GbE or faster NICs plus NVMe arrays. Cooling needs an SP6 server sink for 180 W with front-to-back flow. Lower cTDP trims clocks for hot aisles.

Upgrade paths

On single socket SP6 the upward moves are higher-core Siena parts where vCPU counts grow, without adding sockets. Memory growth to 6 channels and networking additions often help more than cores. The 32-core point already balances threads and power for branch clouds.

Outside Siena, Genoa on SP5 adds channels and sockets for larger fabrics. Most 8324P owners expand memory and IO on SP6 first, since 32 efficient cores already cover dense edge hosts.
