AMDhas published an updated roadmap for its line of EPYCserverprocessors, extending until the end of 2024.
During apresentationfor investors, the company revealed that itsfourth-generation EYPC chipsare on track to launch in 2023. The range will also benefit from two new additions: Genoa-X, equipped with 3D V-Cache and optimized for technical computing workloads, and Siena, targeted at edge and telecoms use cases.
AMD went on to tease new EPYC chips based on its Zen 5 architecture, codenamed Turin, which promise a significantly larger generation-on-generation performance increase courtesy of a complete redesign. These fifth-generation chips are scheduled to come to market within the next two years.
AMD EPYC Genoa-X and Siena
Although AMD remained tight-lipped on the specs for its upcoming Turin chips, the firm did dive deeper into the new additions to its fourth-generation EPYC portfolio.
Genoa-X will fill the same gap in the lineup as Milan-X chips, taking advantage of advanced die-stacking technology (3D V-Cache) to offer upwards of 1GB L3 cache per socket, more than any x86-based chip currently on the market.
This will make them ideally suited for workloads that rely on large quantities of data, such as computational fluid dynamics and structural analysis. AMD has previously described these workloads as essential for “companies that must model the complexities of the physical world” to inform the design of innovative new products.

The new Genoa-X chips will come in multiple flavors, each catering to different performance requirements, with core counts climbing as high as 96. If the previous-generation are anything to go by, theywon’t come cheap.

AMD EPYC Siena chips, meanwhile, are optimized for performance per watt, which makes them the sensible choice for space-constrained edge computing scenarios and less performance-dependent telecoms use cases.
These new chips will join general-purpose EPYC Genoa chips and high-core count,cloud-optimized Bergamo processors, rounding out the lineup by covering off a full gamut of use cases.
