AMD EPYC Genoa Server CPU Details Leak Out - Massive 96 Zen 4 Cores In Up To 12 Chiplets, DDR5/PCIe 5 Support, LGA 6096 Socket

Details of AMD's next-generation EPYC Genoa Server CPU lineup which will feature the Zen four core architecture have leaked out past ExecutableFix. The details point out various specifications for the upcoming lineup and the respective SP5 platform which will succeed AMD'south existing SP3 platform that has lasted three generations of EPYC CPUs including Naples, Rome, and the upcoming, Milan.

AMD EPYC Genoa Server CPU Details Leak Out - Massive 96 Zen 4 Cores In Up To 12 Chiplets, DDR5/PCIe five Support, LGA 6096 Socket

Nosotros accept heard some picayune tidbits about AMD'southward EPYC Genoa in the by but it looks like the latest tweet by ExecutableFix spills the beans on the grandest EPYC launch to date. AMD will be moving over to a new platform and introducing so many new features that each one deserves a special mention of its own. The Genoa lineup is pinned to ship later this year with a hard launch around 2022.

96-cores (192 threads)
12-channel DDR5-5200
128 PCIe 5.0 lanes (160 for 2P)
320W TDP (cTDP 400W) 🔥
SP5 (LGA-6096) socket

Genoa anybody 😍

Starting with the details, AMD has already announced that EPYC Genoa would exist 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 as well feature support for new memory and new capabilities. In the latest details, it is reported that the SP5 platform will also feature a brand new socket that will feature 6096 pins adjust in the LGA (Land Grid Array) format. This will be past far the biggest socket that AMD has ever designed with 2002 more pins than the existing LGA 4094 socket.

The socket will support AMD'south EPYC Genoa and time to come generations of EPYC chips. Talking about Genoa CPUs themselves, the chips will pack a mammoth 96 cores and 192 threads. These volition exist based on AMD'south make new Zen iv cadre architecture which is expected to evangelize some insane IPC uplifts while utilizing the TSMC 5nm process node. A recent rumor had pointed out that the AMD EPYC Genoa CPUs are expected to offer up to 29% IPC uplift over Milan CPUs and a 40% overall comeback thanks to other key technologies that we volition become to in a bit.

To become to 96 cores, AMD has to pack more than cores in its EPYC Genoa CPU package. 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 four compages. 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 characteristic TDPs of 320W which will be configurable up to 400W.

Now that's i surface area which has seen a massive increase. The current meridian parts max out at 280W TDPs so a TDP of 400W is an insane 120W more than than Milan. But given the increased performance and cadre counts, nosotros can definitely wait some meridian-notch efficiency for Genoa. At the aforementioned time, we can also expect faster clock speeds, specially the base frequencies which could take a direct benefit of the increased TDP. The IO die will be separate from the CCD's and that volition bring upwards the total chiplet count on the flake to xiii.

Other than that, it is stated that AMD'due south EPYC Genoa CPUs will feature 128 PCIe Gen 5.0 lanes, 160 for a 2P (dual-socket) configuration. The SP5 platform volition also feature DDR5-5200 memory support which is some insane improvement over the existing DDR4-3200 MHz DIMMs. But that's not all, it volition also support up to 12 DDR5 memory channels and 2 DIMMs per aqueduct which volition allow up to iii TB of system memory using 128 GB modules.

The main competitor of AMD's EPYC Genoa lineup would exist Intel's Sapphire Rapids Xeon family which is expected to launch in 2022 likewise with PCIe Gen five and DDR5 memory support. The lineup was recently rumored to not get a book ramp until 2023 which yous tin read more virtually over hither. Overall, AMD's Genoa lineup seems to be in keen class afterwards this leak and could be a major disruption for the server segment if AMD plays its cards right till Genoa'southward launch.
