AMD confirms its Zen4 EPYC CPUs
At the Accelerated Data Center conference, AMD unveiled its plans for next-gen Zen4 microarchitecture.
AMD is to launch two high-performance processor architectures based on Zen4. The EPYC series codenamed Genoa will feature up to 96 cores and support the latest DDR5 memory technology standard as well a PCI-Express 5.0 It will also be AMD’s first platform with CXL interface support. According to AMD’s estimates, Genoa CPUs is to launch next year, but the company did not specify the exact time frame.
“Genoa” is expected to be the world’s highest performance processor for general purpose computing. It will have up to 96 high-performance “Zen 4” cores produced on optimized 5nm technology, and will support the next generation of memory and I/O technologies with DDR5 and PCIe® 5. “Genoa” will also include support for CXL, enabling significant memory expansion capabilities for data center applications. “Genoa” is on track for production and launch in 2022.
AMD also confirmed EPYC Bergamo which is to feature a new cloud-optimized Zen4c microarchitecture, contrary to the rumors which suggested Zen4d (dense). AMD has confirmed that Bergamo will feature up to 128 cores making it the highest core count from any x86 processors released thus far.
“Bergamo” is a high-core count CPU, tailor made for cloud native applications, featuring 128 high performance “Zen 4c” cores. AMD optimized the new “Zen 4c” core for cloud-native computing, tuning the core design for density and increased power efficiency to enable higher core count processors with breakthrough performance per-socket. “Bergamo” comes with all the same software and security features and is socket compatible with “Genoa.” “Bergamo” is on track to ship in the first half of 2023.
A new roadmap has been shown as well, which confirms that Zen4 products will be based on 5nm process technology. While the roadmap may suggest that Bergamo appears in 2022, it is not until the first half of 2023 that AMD will launch its new cloud EPYC series.
