AMD EPYC 4364P socket: AM5

What the EPYC 4364P is

The EPYC 4364P is an 8-core, 16-thread server processor that AMD released in May 2024 with the EPYC 4004 series for entry servers. Zen 4 Raphael cores run at 4.5 GHz base with boost to 5.4 GHz. Shared L3 cache totals 32 MB. Default TDP is 105 W.

High clocks with server validation define the value: 5.4 GHz boost leads the AM5 server line for hosted applications that charge per thread. The silicon matches the desktop Raphael family such as the AMD Ryzen 7 7800X3D platform generation, while firmware, ECC and availability target single-socket servers. The boxed ordering part is 100-100001477WOF with tray 100-000001477.

ECC memory is supported through UDIMM and RDIMM where the server board wires it, which separates this line from desktop Ryzen on the same socket. The multiplier story is undocumented on the AMD page, so this page makes no locked or unlocked claim. Launch pricing was set at 399 USD per 1Ku tray quantities. Small hosts often pair the 4364P with a single fast NIC and boot NVMe, which covers dedicated hosting with lanes to spare.

Workload fit is entry hosting at speed: small business servers with a handful of tenants, dedicated game hosts where tick rates matter, and branch infrastructure that needs server validation without watts. Operators pick the 4364P where 8 fast cores cover the tenants and the alternative was a hotter, hungrier platform for the same work.

Socket and motherboard compatibility

The 4364P fits the AM5 socket in LGA-1718 packaging on single-socket server boards. Only 1P designs take EPYC 4004 SKUs, since the series targets entry servers rather than scale-out platforms. The board maker CPU support list confirms the SKU with its minimum BIOS, and server boards ship with the supporting firmware.

Consumer AM5 boards share the socket but not the validation: server boards add ECC routing, BMC management and 24-hour duty firmware that desktop boards omit. Buyers should choose purpose-built EPYC 4004 boards for production hosting rather than repurposed desktop models. Hosting providers often standardize on one EPYC 4004 board across edge points for common spares and firmware.

The 6-core AMD EPYC 4244P below shares the platform for lighter duty at lower power. Sockets, memory generation and PCIe generation match across both for common spares in small fleets.

Memory, PCIe and cooling

DDR5-5200 ECC across 2 channels is the rated fit through UDIMM and RDIMM per board support. Entry servers rarely need more channels, but matched pairs still matter for bandwidth uniformity across 8 cores. ECC corrects single-bit faults before they crash hosted tenants, which is the core reason this line exists beside desktop Ryzen.

PCIe 5.0 x28 lanes from the CPU serve NVMe, networking and an optional accelerator on entry boards. Twenty-eight lanes cover boot storage plus fast networking with room for one expansion card. Board manuals define slot wiring per chassis for each deployment.

Cooling at 105 W uses server-rated tower or rack heatsinks matched to chassis airflow. Tray and WOF editions ship without a cooler. The AM5 fixed-backplate pattern from the CPU cooler compatibility by socket guide applies, with server vendors qualifying specific sinks per board.

Upgrade paths

Inside AM5 the 4364P grows from the 6-core AMD EPYC 4244P for threads at higher power, reusing board and memory with a BIOS check. Larger 4004 options add cores for denser hosting on the same platform. Each step keeps ECC memory and server firmware intact.

Moving to the Zen 5 based EPYC 4005 series such as the AMD EPYC 4345P brings newer cores on the same socket for refresh cycles. Leaving AM5 entirely means new boards with fresh memory qualification for larger platforms.
