Another AMD EPYC Genoa ‘Zen 4’ CPU Leaks Out, but this one has 16 cores and two Zen 4 Complex Dies

Another AMD EPYC Genoa CPU, this one having 16 cores and two Zen 4 Core Complex Dies, has been spotted. Videocardz received the most recent images, which show X-Ray images of what lies beneath the gigantic Genoa IHS.

Another AMD EPYC Genoa CPU leaked a few weeks ago, and this one shows that the prototypes are already being given out to clients in the HPC and Cloud Computing industries.

The AMD EPYC Genoa chip is built on the SP5 socket, which has a total of 6096 LGA contacts, the most ever seen on a server chip. It has 16 cores and 32 threads and is built on the Zen 4 architecture, which uses the latest TSMC 5nm node.

Only two of the twelve CCDs are used in this configuration, making it an entry-level model. The full fat configuration will have 12 Zen 4 CCDs, each with 8 cores, totalling 96 cores. This sample is either the OPN 100-000000627-08 (ES0) or OPN 100-000000627-12 (ES1) variety, according to ExecutableFix. In addition to this, the insider has reported OPNs for the 96 Core and 32 Core variants, which are 100-000000475-16 and 100-000000479-10, respectively.

The CPU consumes 195 watts of electricity and has a maximum boost frequency of 3.7 GHz. These are not the final clock rates; in the final lineup, we can expect a 16 core model with clock speeds of above 4.0 GHz. The 16 core part would also come in 5 chipset configurations, according to the leaked EPYC Genoa specifications, with four partially disabled Zen 4 CCDs with four cores each, a 195W TDP, a 116W power for the IOD, and a 3.3W LGA power design. Aside from that, the socket will be separated into four parts, each of which will include 1520 contact pads.

AMD EPYC Genoa CPUs – 5nm Zen 4 & Up To 96 Cores In 2022

To begin with, AMD has already stated that EPYC Genoa would be compatible with the new SP5 platform, which includes a new socket, and that SP3 compatibility will be available until EPYC Milan. New memory and capabilities would be supported by the EPYC Genoa CPUs. According to the newest information, the SP5 platform will also include a completely new socket with 6096 pins grouped in the LGA (Land Grid Array) configuration. With 2002 more pins than the present LGA 4094 socket, this will be AMD’s largest rocket ever.

The socket will support AMD’s EPYC Genoa processor as well as future EPYC models. When it comes to Genoa CPUs, the chips will have a whopping 96 cores and 192 threads. These will be based on AMD’s brand new Zen 4 core architecture, which is projected to produce enormous IPC boosts while using TSMC’s 5nm production node.

AMD will have to squeeze more cores into its EPYC Genoa CPU box to reach 96 cores. AMD claims to have achieved this by including up to 12 CCDs in their Genoa chip. The Zen 4 architecture will be used to power each CCD, which will have eight cores. We could be looking at a big CPU interposer, even larger than the present EPYC CPUs if this corresponds with the increased socket size. The CPU is believed to have a TDP of 320W, which may be increased to 400W. More information about the SP5 platform may be found here.

Aside from that, AMD’s EPYC Genoa CPUs will have 128 PCIe Gen 5.0 lanes, with 160 available in a 2P (dual-socket) configuration. The SP5 platform will also enable DDR5-5200 memory, which is a significant upgrade above the current DDR4-3200 MHz DIMMs. Not only that, but it will also support up to 12 DDR5 memory channels with two DIMMs per channel, allowing for up to 3 TB of system memory with 128 GB modules.

Intel’s Sapphire Rapids Xeon series, which is also anticipated to ship in 2022 with PCIe Gen 5 and DDR5 memory compatibility, will be AMD’s major competition. The lineup is reported to be getting a volume increase in 2023, which you can read more about here. Overall, AMD’s Genoa portfolio appears to be in fine shape following this leak, and if AMD plays its cards properly until Genoa’s introduction in 2022, it might cause a huge disruption in the server market.
