Description:
AMD has published a new roadmap for its next generation EPYC CPUs.

FULL STORY ======================================================================

AMD has unveiled an updated roadmap for its fourth-generation EPYC server chips, which the company says will enter production and become available next year.

Codenamed Genoa, the next generation of EPYC CPUs will be based on AMDs new Zen 4 architecture, the first to utilize TSMCs 5nm process technology.

According to Dr. Lisa Su, AMD CEO, 5nm EPYC chips will offer twice the density, twice the power efficiency and 1.25 times the performance achieved
by the 7nm process on which the companys third-gen EPYC chips are built.

The top-tier Genoa SKUs will have up to 96 Zen 4 cores, and support next generation DDR5 and PCIe 5.0 memory and I/O technologies.

When introduced, we expect Genoa will be the worlds highest performance processor for general purpose computing, said Su. Its designed to excel
across a broad range of workloads, from enterprise to HPC and the cloud . AMD Bergamo

In addition to fresh details about its fourth-generation EYPC chips, AMD also announced an offshoot of its Zen 4 architecture thats optimized for specific cloud use cases, called Zen 4c.

Cloud native workloads are a fast-growing class of application that are developed, deployed and updated rapidly, Su explained. These applications typically are very throughput-oriented and can take advantage of a high
number of threads.

Weve created a new version of Zen 4 specifically for cloud-native computing, with specific enhancements including a new density-optimized cache hierarchy to enable additional higher core-count configurations for cloud-native workloads that benefit from maximum thread density.

Su went on to claim that Zen 4c architecture will boast improved power efficiency and superior performance per socket.

The new architecture will be first deployed in a new line of processors designed for cloud native applications, called Bergamo. The Bergamo series will offer up to a whopping 128 Zen 4c cores and deliver breakthrough performance and efficiency for cloud-native workloads, as well as benefiting from all the same features as Genoa (DDR5, PCIe 5.0 etc.).

As per the new roadmap, AMDs Bergamo chips are set to launch in the first
half of 2023.
