Socket SP5 is a microprocessor socket designed by AMD for the fourth generation of their EPYC family of high performance server processors, succeeding Socket SP3. Its counterpart for desktop processors is Socket AM5.

Overview[edit]

Symbol version future.svg Preliminary Data! Information presented in this article deal with future products, data, features, and specifications that have yet to be finalized, announced, or released. Information may be incomplete and can change by final release.

Socket SP5 is a zero insertion force, heatsink actuated, surface-mount land grid array socket for use with a 6096-contact, 0.94 mm × 0.81 mm interstitial pitch, organic land grid array CPU package.

It supports 12 channels of DDR5 memory with two 40-bit subchannels (32 bit data + 8 bit ECC) and up to 2 DIMMs per channel, eight 16-lane PCIe Gen 5 I/O links, three or four of which are repurposed as inter-socket links on dual socket systems, two 4-lane PCIe Gen 3 links, four USB 3.1 Gen 1 ports, and up to 32 SATA Gen 3 ports.

This compares to eight 72-bit DDR4 channels and eight 16-lane PCIe Gen 3/4 links on its predecessor Socket SP3. (SP4 and SP4r2 are ball grid array packages of EPYC 3000 embedded processors.)

The following AMD processor families use Socket SP5:

CPU Family Microarch. Process Products
Type 0 Family 19h Models 10h–1Fh Zen 4 5 nm EPYC 9004 "Genoa" (Model 11h)

The codename of AMD's SP5 reference platform (CRB) is "Titanite".

Package Description[edit]

The SP5 CPU package is lidded, has a 72 mm × 75.4 mm organic substrate with flip chip die attachment, 6096 land pads with gold over nickel plating, and leaves AMD's OSAT partner in a shipping tray with a carrier frame pre-installed. The carrier frame is a part of the package loading mechanism and remains on the package in the socket.

The package has the same length (75.4 mm) as the Socket SP3 package but no keying notches and a redesigned lid bridging the chiplets and decoupling capacitors on the package top with flanges on only two sides, providing more space for these components. Additional components are placed on the package bottom side. While the package has no apparent anti-rotation features, the carrier frame fits into the socket's rail frame in just one orientation. SP5 processors are electrically keyed by pin SP5R1 to SP5R4. To boot the processor compatible firmware is also required. A triangular symbol on both sides of the substrate marks the location of pin A1, with corresponding markings on the socket.

Type-0 packages are multi-chip modules integrating one I/O die and up to 12 Core Complex Dies which contain eight CPU cores each. A GMI3 link connects each CCD to the IOD.

Socket SP5 has 12 DDR5 memory channels A-L and supports up to 2 DIMMs per channel. Each channel has two independent subchannels with a 32-bit data and 8-bit ECC bus. Type-0 processors support SR/DR RDIMMs, 4R/8R LRDIMMs and 3DS RDIMMs, EC8 (80 bit wide) modules with x4 or x8 DRAM devices, or EC4 (72 bit) with x4 devices.

Like the prior generation Socket SP5 supports eight 16-lane multi-function I/O interfaces P0-P3 and G0-G3. All of these interfaces can be configured as PCIe links, some alternatively as xGMI link, and some lanes as CXL or SATA link.

On dual socket (2P) systems the cache coherent xGMI links connect the Data Fabrics of each processor. Socket SP5 processors can use three or four xGMI links depending on bandwidth requirements using the G0-G3 interfaces, or four links between G0, G2, P1, and P3. xGMI links use 16 lanes, unused links release 16 lanes per socket for I/O. As with PCIe links the maximum raw data rate is 32 GT/s. A WAFL link connects the Control Fabrics of each processor, i.e. the PSP, SMUs and other IPs, primarily for temperature monitoring, power and frequency control. Physically they use the PCIe Gen 3 protocol.

Compute Express Links enable cache coherent links to peripheral devices. Type-0 processors are CXL 1.1 compliant and support CXL Type 1 devices (specialized accelerators with no local memory such as a NIC using the CXL.io and CXL.cache protocols) and CXL Type 3 devices (memory expanders, using the CXL.io and CXL.memory protocols) on the P0-P3 interfaces. Up to four CXL Type 1 devices are supported per socket, up to four Type 3 devices per 16-lane interface.

Like its predecessor this socket supports various low speed interfaces. It adds support for the I3C protocol while the LPC interface was deprecated in favor of SPI/ESPI. These busses are generally used to access firmware (PSP ROM and BIOS) i.e. flash memory, and a TPM. Socket SP5 also reserves some pins for audio interfaces, perhaps for future HEDT or workstation processors.

Socket Description[edit]

Socket SP5 has a 93.4 mm × 120.3 mm footprint and consists of the following components, from top to bottom:

  • Retention Frame
  • Rail Frame
  • Socket Housing
  • Stiffener Frame
  • Insulators
  • Backplate

Removable components are:

  • Heatsink
  • Carrier Frame
  • External Cap
  • PnP Cover Cap

The retention frame, rail frame, and stiffener frame constitute the Socket Retention Mechanism. The heatsink, the CPU in a carrier frame, the SRM, housing, and backplate are separately orderable parts. The latter three are motherboard components for OEMs. Socket SP5 suppliers are Lotes Co. Ltd. (website), Foxconn Interconnect Technology (website), and Amphenol Corp.

LGA sockets use cantilever springs in the socket housing to make electrical contact with flat pads on the bottom of the CPU package. An independent loading mechanism creates the Z-axis compression load between the CPU package and the housing. Considerable force is required to deflect thousands of springs at once which rules out a lever mechanism in favor of screw actuation. The Socket SP5 retention mechanism provides sufficient force to secure the CPU in a mating position, but this socket is actuated by the heatsink, which is attached to the stiffener frame and the backplate. The stiffener frame is likewise attached to the backplate on the bottom side of the motherboard.

The retention frame is a largely flat piece stamped out of stainless steel sheets. It has a window allowing the top of the CPU package lid to protrude for contact with the heatsink. In locked state it applies a load to the flanges on two sides of the lid. The retention frame is attached to the stiffener frame by a hinge which permits vertical motion when the socket is actuated, integrates a stop feature limiting the opening angle, and a torsional spring to keep the frame open while the user inserts or removes the CPU. The retention frame is locked using a single captive screw with a Torx T20 head and M3.5×0.6 or larger thread. It mates with a self-clinching PEM nut on the stiffener frame.

The heatsink is attached using six captive nuts, also with a Torx T20 head. Four of these mate with four 10.0 mm high standoffs with an M3.5×0.6 external thread in the corners of the stiffener frame. These standoffs have conical tips for alignment. Two additional studs with the same threading protude up from the backplate, through openings in the motherboard, insulator sheets, stiffener frame, rail frame, retention frame, and carrier frame, securing the heatsink on the sides of the processor. Backplates with stud heights from 14.40 to 16.00 mm are available to account for different PCB thicknesses. The studs and nuts are symmetrically arranged so the heatsink can be installed 180 degrees rotated. The middle screws are supposed to be tightened first, then diagonally opposed corner screws, with a torque between 12.5 and 15 kgf-cm according to AMD (1.23 to 1.47 N⋅m).

The remaining components have the same function as on Socket SP3. Socket SP5 carrier frames are color coded, the color of frames for EPYC 7004 series processors is TBD.
