AMD EPYC Embedded 8224P socket: SP6

What the EPYC Embedded 8224P is

The EPYC Embedded 8224P is the 24-core Siena embedded part for single socket SP6 in September 2023. Twenty-four Zen 4c small cores with multithreading run at 2.55 GHz base and up to 3.0 GHz boost with matching all-core boost, backed by 24 MB of L2 and 64 MB of L3. The TSMC 5 nm package targets 160 W inside a 155 to 225 W window for efficient embedded racks with long supply. It shares Siena silicon with the server 8224P but adds embedded qualification.

Balanced threads with modest power suit embedded branch clouds and storage nodes that need vCPUs plus server IO. Twenty-four cores share 64 MB of L3 for locality, while 6 DDR5-4800 ECC channels keep board cost down. Ninety-six Gen5 lanes serve networking and NVMe for single-socket designs. Power stays moderate for dense embedded shelves.

Buyers choose embedded Siena for lifecycle with server IO rather than for maximum threads. It matches the server 8224P in clocks and cache but extends supply for industrial fleets. Smaller 16-core parts trim power on the same SP6 base. The Socket vs chipset: what decides whether a CPU works guide is secondary to SP6 embedded board lists.

Socket and motherboard compatibility

The Embedded 8224P fits SP6 on single socket embedded boards with LGA 4844 frames. Siena is 1P-only, so dual socket pairing is not supported. Board lists must name Siena Embedded 8004 for boot support. Power delivery for 160 W continuous suits 1U embedded chassis.

SP6 embedded boards wire 6 DDR5 channels with one DIMM per channel for best speed in many layouts. BMC firmware covers remote management for far-flung nodes. Confirm heatsink height for dense 24-core nodes.

Memory, PCIe and cooling

DDR5-4800 ECC RDIMM in 6 channels feeds 24 small cores for embedded clouds. Capacity scales with large DIMMs. 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 24-core node typically wires NICs plus NVMe arrays. Cooling needs an SP6 server sink for 160 W with front-to-back flow.

Upgrade paths

On single socket SP6 the upward moves are 32-core and higher embedded Siena parts where vCPU counts grow, without adding sockets. Memory growth to 6 channels and networking additions often help more than cores. The 24-core point balances threads and power for embedded use.

Outside Siena, Genoa embedded on SP5 adds channels and sockets for larger fabrics. Most Embedded 8224P owners expand memory and IO on SP6 first.
