Genoa is the codename of AMD's EPYC 9004 series of high-performance microprocessors based on the Zen 4 microarchitecture for single- and dual-socket server platforms. Launched in November 2022 it succeeded the third generation of EPYC processors, the EPYC 7003 "Milan" series.^[1]

EPYC 9004 processors identify as members of AMD CPU Family 19h, Model 11h (engineering samples as Model 10h).

Memory Interface

The "Genoa" I/O die integrates 12 DDR5 memory controllers and interfaces, three per I/O die quadrant, which support raw data rates up to 4800 MT/s. Up to 2 DIMMs per channel are supported. Each channel has two independent 40-bit (32 data, 8 ECC) DDR5 subchannels. The memory controllers support ECC memory (80b x4, 80b x8, and 72b x4 ECC, i.e. EC4 and EC8 DIMMs) and DDR5 DRAMs with 16/24/32 Gb density on the following DIMM types:

SR/DR RDIMM built with x4 and x8 DDR5 devices (1Rx4 16/32/48 GiB, 1Rx8 16/24 GiB, 2Rx4 64/80/96 GiB, 2Rx8 32/40/48 GiB)
4R/8R LRDIMM (2S2R, 2S4R)
4R/8R/16R 3DS DIMM built with x4 devices (2S2Rx4 128/192 GiB, 2S4Rx4 256/384 GiB, 2S8Rx4 512 GiB)

UDIMM, NVDIMM-N, NVDIMM-P types are not supported.

The maximum total memory capacity is 6 TiB per socket using 3DS DIMMs of e.g. 12 × 512 GiB capacity.

Input/Output Interfaces

The "Genoa" I/O die integrates eight 16-lane PCIe Gen 5 (32 GT/s) controllers and interfaces. Link bifurcation permits configuration of the PCIe lanes as x16, x8, x4, x2, or x1 wide independent links, e.g. 1x8 + 1x4 + 4x1. Each controller supports up to nine PCIe links, or up to eight if any lane is is configured as SATA link, and per link lane reversal which can simplify signal routing on the motherboard.

Two supplementary I/O interfaces support the PCIe Gen 3 (8 GT/s) protocol. Each of these interfaces has four lanes configurable x4, x2, x1 and supports up to four links.

On dual-socket systems four, or optionally three depending on bandwidth requirements, x16 links are repurposed for cache coherent inter-socket traffic. The raw data rate of these xGMI links is also 32 GT/s. A WAFL link occupying two lanes on one of the supplementary interfaces connects the Control Fabrics of each processor, i.e. the PSP, SMUs and other IPs, primarily for temperature monitoring, power and frequency control.

In summary on 1P systems up to 128 PCIe Gen 5 and 8 PCIe Gen 3 lanes are available for I/O. On 2P systems up to 64 or 80 PCIe Gen 5 and 6 PCIe Gen 3 lanes per socket.

Up to four of the x16 interfaces can be configured as cache-coherent Compute Express Link. "Genoa" supports version 1.1 of the protocol, specifically accelerators without local memory such as a NIC using the CXL.io and CXL.cache protocols, and memory expanders using the CXL.io and CXL.memory protocols. One accelerator per interface can be attached with a 1x16 or 1x8 link, or up to four memory expanders with 1x16, 2x8, or 4x4 links. Unused lanes are available for PCIe and configurable 1x8, 2x4, or 3x4.

The lanes on two x16 interfaces can be configured as SATA Gen 3 links, unused lanes are available for PCIe. On 1P systems up to 32 SATA ports total are available, on 2P systems 16 ports per socket as one of the interfaces is reserved for xGMI duty.

The processors integrate a controller hub with four USB 3.2 Gen 1×1 (5 Gb/s) ports (the I/O die actually implements USB 3.2 Gen 2×1^[2] which may be available on future Ryzen Threadripper processors) and several low-speed interfaces listed below.

For link configuration details see Socket SP5.
