Another AMD EPYC Genoa ‘Zen 4’ CPU Leaks Out, This…

One more AMD EPYC Genoa 'Zen 4' CPU Leaks Out, This Time A 16 Core Chip With two Lively CCDs

A different AMD EPYC Genoa CPU has been pictured which will come with 16 cores inside of two Zen 4 Main Elaborate Dies.

The most up-to-date photos were acquired by Videocardz and show X-Ray shots of what lies underneath the large Genoa IHS. An additional AMD EPYC Genoa CPU had just leaked out a number of months earlier and this new one particular shows proves that the 1st samples are already becoming sent out to clients that in HPC & Cloud Computing segments.

As for the CPU itself, the AMD EPYC Genoa chip is primarily based all-around the SP5 socket which capabilities a total of 6096 LGA contacts, the maximum at any time on any server chip at the minute. It arrives with a whole of 16 cores and 32 threads primarily based on the Zen four architecture which makes use of the most recent TSMC 5nm node. This is specifically an entry-stage configuration as it only options two of the twelve CCDs. The complete fats configuration will characteristic twelve Zen 4 CCDs with eight cores for each CCD for a overall of ninety six cores. As for every ExecutableFix, this sample is both the OPN a hundred-000000627-08 (ES0) or OPN one hundred-000000627-12 (ES1) variant. Apart from these, the insider has also noted OPNs for the ninety six Main and 32 core variants which are 100-000000475-16 and 100-000000479-10, respectively.

The CPU by itself consumes 195W electrical power and has a highest improve clock of up to three.seven GHz. These are not the final clock speeds as we can expect a 16 core variant with above 4. GHz clock speeds in the closing lineup. As mentioned in the leaked EPYC Genoa documents, the sixteen main section would also arrive in 5 chiplet configurations, that includes four partially disabled Zen four CCDs with four cores each individual, a 195W TDP, a 116W electricity for the IOD, and a three.3W LGA energy style and design. Other than that, the socket itself will be divided into four segments, each with 1520 call pads.

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

Setting up with the particulars, AMD has now announced that EPYC Genoa would be suitable with the new SP5 platform which provides a new socket so SP3 compatibility would exist up till EPYC Milan. The EPYC Genoa processors would also feature help for new memory and new abilities. In the most up-to-date details, it is claimed that the SP5 platform will also function a model new socket that will attribute 6096 pins arranged in the LGA (Land Grid Array) format. This will be by considerably the most important socket that AMD has ever designed with 2002 more pins than the current LGA 4094 socket.

AMD EPYC Milan Zen three vs EPYC Genoa Zen 4 Dimension Comparisons:

CPU Identify AMD EPYC Milan AMD EPYC Genoa
Approach Node TSMC 7nm TSMC 5nm
Core Architecture Zen 3 Zen 4
Zen CCD Die Dimensions 80mm2 72mm2
Zen IOD Die Measurement 416mm2 397mm2
Substrate (Offer) Space TBD 5428mm2
Socket Place 4410mm2 6080mm2
Socket Name LGA 4094 LGA 6096
Max Socket TDP 450W 700W

The socket will help AMD’s EPYC Genoa and future generations of EPYC chips. Talking about Genoa CPUs themselves, the chips will pack a mammoth ninety six cores and 192 threads. These will be based on AMD’s model new Zen four core architecture which is predicted to provide some insane IPC uplifts while utilizing the TSMC 5nm method node.

To get to ninety six cores, AMD has to pack much more cores in its EPYC Genoa CPU offer. AMD is stated to accomplish this by incorporating a full of up to twelve CCD’s in its Genoa chip. Every single CCD will element eight cores primarily based on the Zen four architecture. That aligns with the improved socket dimensions and we could be seeking at a significant CPU interposer, even larger than the existing EPYC CPUs. The CPU is reported to attribute TDPs of 320W which will be configurable up to 400W. You can find a lot more specifics concerning the SP5 platform here.

Other than that, it is mentioned that AMD’s EPYC Genoa CPUs will feature 128 PCIe Gen five. lanes, 160 for a 2P (twin-socket) configuration. The SP5 platform will also feature DDR5-5200 memory support which is some insane improvement about the current DDR4-3200 MHz DIMMs. But which is not all, it will also help up to 12 DDR5 memory channels and two DIMMs per channel which will allow up to 3 TB of program memory using 128 GB modules.

The most important competitor of AMD’s EPYC Genoa lineup would be Intel’s Sapphire Rapids Xeon family which is anticipated to launch in 2022 too with PCIe Gen 5 and DDR5 memory guidance. The lineup was a short while ago rumored to not get a quantity ramp until finally 2023 which you can examine additional about in excess of in this article. Total, AMD’s Genoa lineup looks to be in great type immediately after this leak and could be a main disruption for the server section if AMD plays its playing cards ideal until Genoa’s start by 2022.
