One other AMD EPYC Genoa ‘Zen 4’ CPU Leaks Out, This Time A 16 Core Chip With 2 Energetic CCDs

One other AMD EPYC Genoa CPU has been pictured which comes with 16 cores inside two Zen 4 Core Complicated Dies.

The most recent photos had been obtained by Videocardz and present X-Ray photographs of what lies beneath the large Genoa IHS. One other AMD EPYC Genoa CPU had simply leaked out a number of weeks earlier and this new one reveals proves that the primary samples are already being despatched out to prospects that in HPC & Cloud Computing segments.

As for the CPU itself, the AMD EPYC Genoa chip is predicated across the SP5 socket which contains a whole of 6096 LGA contacts, the very best ever on any server chip for the time being. It comes with a complete of 16 cores and 32 threads primarily based on the Zen 4 structure which makes use of the newest TSMC 5nm node. That is notably an entry-level configuration because it solely options two of the twelve CCDs. The total fats configuration will characteristic 12 Zen 4 CCDs with 8 cores per CCD for a complete of 96 cores. As per ExecutableFix, this pattern is both the OPN 100-000000627-08 (ES0) or OPN 100-000000627-12 (ES1) variant. Except for these, the insider has additionally reported OPNs for the 96 Core and 32 core variants that are 100-000000475-16 and 100-000000479-10, respectively.

The CPU itself consumes 195W energy and has a most enhance clock of as much as 3.7 GHz. These usually are not the ultimate clock speeds as we are able to count on a 16 core variant with over 4.0 GHz clock speeds within the remaining lineup. As famous within the leaked EPYC Genoa paperwork, the 16 core half would additionally are available in 5 chiplet configurations, that includes 4 partially disabled Zen 4 CCDs with 4 cores every, a 195W TDP, a 116W energy for the IOD, and a 3.3W LGA energy design. Aside from that, the socket itself will likely be divided into 4 segments, every with 1520 contact pads.

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

Beginning with the main points, AMD has already introduced that EPYC Genoa can be suitable with the brand new SP5 platform which brings a brand new socket so SP3 compatibility would exist up until EPYC Milan. The EPYC Genoa processors would additionally characteristic assist for brand new reminiscence and new capabilities. Within the newest particulars, it’s reported that the SP5 platform will even characteristic a model new socket that can characteristic 6096 pins organized within the LGA (Land Grid Array) format. This will likely be by far the most important socket that AMD has ever designed with 2002 extra pins than the present LGA 4094 socket.

The socket will assist AMD’s EPYC Genoa and future generations of EPYC chips. Speaking about Genoa CPUs themselves, the chips will pack a mammoth 96 cores and 192 threads. These will likely be primarily based on AMD’s model new Zen 4 core structure which is predicted to ship some insane IPC uplifts whereas using the TSMC 5nm course of node.

To get to 96 cores, AMD has to pack extra cores in its EPYC Genoa CPU bundle. AMD is claimed to realize this by incorporating a complete of as much as 12 CCD’s in its Genoa chip. Every CCD will characteristic 8 cores primarily based on the Zen 4 structure. That aligns with the elevated socket dimension and we could possibly be taking a look at an enormous CPU interposer, even bigger than the present EPYC CPUs. The CPU is claimed to characteristic TDPs of 320W which will likely be configurable as much as 400W. Yow will discover extra particulars concerning the SP5 platform right here.

Aside from that, it’s acknowledged that AMD’s EPYC Genoa CPUs will characteristic 128 PCIe Gen 5.0 lanes, 160 for a 2P (dual-socket) configuration. The SP5 platform will even characteristic DDR5-5200 reminiscence assist which is a few insane enchancment over the present DDR4-3200 MHz DIMMs. However that is not all, it would additionally assist as much as 12 DDR5 reminiscence channels and a couple of DIMMs per channel which is able to permit as much as 3 TB of system reminiscence utilizing 128 GB modules.

The principle competitor of AMD’s EPYC Genoa lineup can be Intel’s Sapphire Rapids Xeon household which is predicted to launch in 2022 too with PCIe Gen 5 and DDR5 reminiscence assist. The lineup was lately rumored to not get a quantity ramp till 2023 which you’ll be able to learn extra about over right here. Total, AMD’s Genoa lineup appears to be in nice kind after this leak and could possibly be a serious disruption for the server section if AMD performs its playing cards proper until Genoa’s launch by 2022.
