AMD demonstrates EPYC commitment to the datacenter at the AMD Next Horizon event, where it also announced it’s new 7-nanometer, 64-core CPU code named ‘Rome’.
The new EPYC CPU will use a single die for I/O and logic, with its CPU cores and caches organized into “chiplets.” The new chip demonstrates these chiplets with two 7nm chips on a 14nm I/O DIE, with no memory access penalties thanks to the Infinity Fabric design.
“Combining this breakthrough design methodology with the benefits of TSMC’s leading-edge 7nm process technology, “Zen 2” delivers significant performance, power consumption and density generational improvements that can help reduce datacenter operating costs, carbon footprint and cooling requirements. Other key generational advances over the award-winning “Zen” core include:
- An improved execution pipeline, feeding its compute engines more efficiently.
- Front-end advances – improved branch predictor, better instruction pre-fetching, re-optimized instruction cache and larger op cache.
- Floating point enhancements – doubled floating point width to 256-bit and load/store bandwidth, increased dispatch/retire bandwidth and maintained high throughput for all modes.
- Advanced security features – Hardware-enhanced Spectre mitigations, taking software migration and hardening it into the design, and increased flexibility of memory encryption.
Multiple 7nm-based AMD products are now in development, including next-generation AMD EPYC CPUs and AMD Radeon Instinct GPUs, both of which AMD detailed and demonstrated at the event. Additionally, the company shared that its follow-on 7nm+-based “Zen 3” and “Zen 4” x86 core architectures are on-track.“
AMD also announced the immediate availability of the first AMD EPYC processor-based instances on Amazon Elastic Compute Cloud (EC2). Part of the most popular AWS instance families, the new AMD EPYC processor powered offerings feature industry leading core density and memory bandwidth.
With the availability of new memory optimized (R5) and general purpose (M5 and T3) instances featuring 2.5 GHz AMD EPYC processors, AWS offers 10% lower prices – Amazon Press Room
