AMD in its latest online event made to key EPYC and Instinct announcements, but the company also has teased its next-gen Zen 4 powered Genoa and Bergamo CPU families. The Genoa and Bergamo EPYC chips will be featuring a brand new core architecture and offer up to 96 Zen 4 cores and the latter with an insane 128 Zen 4C core package.
AMD didn’t just unveil that they are bringing Genoa and Bergamo to the EPYC family but also unveiled a brand new chip architecture in the form of Zen 4C. The Zen 4C core was talked about very recently in rumours as Zen 4D and there are some things that we need to discuss the architecture.
AMD EPYC Genoa CPUs – 5nm Zen 4 & Up To 96 Cores In 2022
AMD announced that its EPYC Genoa will be compatible with the new SP5 platform which brings a new socket so SP3 compatibility would exist up till EPYC Milan. The EPYC Genoa processors will be featuring support for new memory and new capabilities and the platform will also feature a brand new socket featuring 6096 pins arranged in the LGA (Land Grid Array) format
this socket will be supporting AMD’s EPYC Genoa as well as future generations of EPYC chips. These mammoth GPUs will come with amazing 96 cores and 192 threads and the company’s brand new Zen 4 core architecture which is expected to deliver some insane IPC uplifts while utilizing the TSMC 5nm process node.
The SP5 platform will also be featuring DDR5-5200 memory support which will bring major improvements over the existing DDR4-3200 MHz DIMMs and the platform will also bring support for up to 12 DDR5 memory channels and 2 DIMMs per channel which will allow up to 3 TB of system memory using 128 GB modules.
AMD EPYC Bergamo CPUs – 5nm Zen 4C & Up To 128 Cores In 1H 2023
We have heard quite a few rumours about the AMD’s EPYC Genoa being 128 core however, let’s answer all those once and for all. AMD has announced that the EPYC Genoa lineup will be featuring TSMC’s 5nm process-based Zen 4 cores and there will be a total of 96 of them. AMD might have evaluated or tested Genoa with 128 cores internally however it seems that the company has decided to go with 96 cores for the final design.
AMD is expected to launch another Zen 4 based server lineup known as Bergamo as the chips will be featuring up to 128 cores and will aim to destroy Intel’s HBM powered Xeon chips along with server products from Apple and Google with higher core counts.
