Another AMD EPYC Genoa 'Zen 4' CPU Leaks Out, This Time A 16 Core Chip With 2 Active CCDs

Another AMD EPYC Genoa CPU has been pictured which comes with 16 cores within ii Zen 4 Core Complex Dies.

The latest pictures were obtained by Videocardz and show X-Ray shots of what lies underneath the massive Genoa IHS. Some other AMD EPYC Genoa CPU had just leaked out a few weeks earlier and this new i shows proves that the first samples are already beingness sent out to customers that in HPC & Cloud Computing segments.

As for the CPU itself, the AMD EPYC Genoa chip is based around the SP5 socket which features a total of 6096 LGA contacts, the highest ever on any server chip at the moment. It comes with a total of sixteen cores and 32 threads based on the Zen 4 architecture which utilizes the latest TSMC 5nm node. This is peculiarly an entry-level configuration as it only features two of the twelve CCDs. The full fat configuration will characteristic 12 Zen iv CCDs with 8 cores per CCD for a total of 96 cores. As per ExecutableFix, this sample is either the OPN 100-000000627-08 (ES0) or OPN 100-000000627-12 (ES1) variant. Aside from these, the insider has too reported OPNs for the 96 Core and 32 core variants which are 100-000000475-16 and 100-000000479-10, respectively.

The CPU itself consumes 195W power and has a maximum boost clock of up to 3.7 GHz. These are not the final clock speeds as we can expect a sixteen cadre variant with over iv.0 GHz clock speeds in the final lineup. As noted in the leaked EPYC Genoa documents, the 16 core role would too come in 5 chiplet configurations, featuring four partially disabled Zen four CCDs with 4 cores each, a 195W TDP, a 116W ability for the IOD, and a three.3W LGA power design. Other than that, the socket itself will be divided into 4 segments, each with 1520 contact pads.

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

Starting with the details, AMD has already announced that EPYC Genoa would be compatible with the new SP5 platform which brings a new socket so SP3 compatibility would exist upward till EPYC Milan. The EPYC Genoa processors would also feature support for new retentivity and new capabilities. In the latest details, it is reported that the SP5 platform will also feature a brand new socket that volition feature 6096 pins arranged in the LGA (Land Filigree Assortment) format. This will be by far the biggest socket that AMD has e'er designed with 2002 more pins than the existing LGA 4094 socket.

Socket Area	4410mm2	6080mm2
Socket Name	LGA 4094	LGA 6096
Max Socket TDP	450W	700W

The socket will support AMD's EPYC Genoa and future generations of EPYC chips. Talking about Genoa CPUs themselves, the fries will pack a mammoth 96 cores and 192 threads. These will exist based on AMD's brand new Zen four core compages which is expected to deliver some insane IPC uplifts while utilizing the TSMC 5nm procedure node.

To get to 96 cores, AMD has to pack more than cores in its EPYC Genoa CPU parcel. AMD is said to achieve this by incorporating a total of up to 12 CCD'south in its Genoa chip. Each CCD will feature 8 cores based on the Zen 4 architecture. That aligns with the increased socket size and we could exist looking at a massive CPU interposer, even larger than the existing EPYC CPUs. The CPU is said to feature TDPs of 320W which will be configurable up to 400W. You tin find more details regarding the SP5 platform hither.

Other than that, it is stated that AMD's EPYC Genoa CPUs will feature 128 PCIe Gen 5.0 lanes, 160 for a 2P (dual-socket) configuration. The SP5 platform volition also characteristic DDR5-5200 retentiveness back up which is some insane improvement over the existing DDR4-3200 MHz DIMMs. But that's non all, information technology volition also back up up to 12 DDR5 memory channels and 2 DIMMs per channel which will permit upward to 3 TB of organisation memory using 128 GB modules.

The master competitor of AMD's EPYC Genoa lineup would be Intel'due south Sapphire Rapids Xeon family which is expected to launch in 2022 as well with PCIe Gen 5 and DDR5 memory support. The lineup was recently rumored to non get a volume ramp until 2023 which you tin read more about over hither. Overall, AMD'southward Genoa lineup seems to be in groovy form after this leak and could exist a major disruption for the server segment if AMD plays its cards right till Genoa's launch by 2022.
