AMD Genoa: What We Know

Genoa, Bergamo, Genoa-X, Siena: AMD's next Generation CPU.

AMD’s 4th Gen EPYC CPUs will supersede the beloved Gen 3 Milan and Milan-X, which were the foundation of many HPC applications and the choice processor for the consensus. Milan-X introduced a groundbreaking technology with 3D V-Cache which employs a hybrid bond plus through silicon vias to overcome the physical limitations of 2D chip designs. 3D V-Cache offered a considerable boost in the L3 cache to mitigate fetching memory from the RAM when intensive workloads need to be executed. What’s next for Gen 4 EPYC?

AMD EPYC CPU Servers Roadmap.

AMD during their Financial Analyst Day showed us their roadmap detailing their goals. Later this year will be the start of 4th Gen EPYC data center CPUs starting with Genoa, their general purpose CPU. In the 1st half of 2023, we are expecting the release of the cloud computing optimized Bergamo, 3D V-Cache variant Genoa-X, and the telecommunications-focused Siera.

This infographic also shows us their plans for 5th Gen EPYC in 2024 with the EPYC Turin which should mirror the same as 4th Gen EPYC with cloud and telecom optimized variants.

96-Core Genoa and Genoa-X

AMD displayed a demo of their 96-Core EPYC Genoa with a performance uplift of up to 75% over Milan mainly stemming from the 12 channel DDR5 and extra 32 cores. Genoa will be the foundation of their other 3 data center CPUs.

We are confident that AMD is choosing to implement 3D chip stacking in Genoa-X which supersedes the Milan-X an already extremely powerful CPU. AMD has confirmed that Genoa will house 96 cores, 12 channel DDR5, and 480 MB of cache (32MB per CCD of L3 and 1MB per core for L2) a staggering amount over Milan-X’s 288MB. The extra cache will enable a faster workload and higher performance by storing recent memory on the CPU instead of constantly fetching from RAM. If the current Milan-X chips are already so powerful, we can’t wait to see Genoa-X. Genoa-X is set to release in 2023.

128-Core Cloud and ARM CPU: Bergamo

Bergamo is AMD’s cloud-native CPU ready with 128 Zen 4c cores ready to tackle heavy containerized workloads and multi-instance iterations. With 256 threads, bottlenecks will be addressed for each user. An extremely dense CPU. When used in conjunction, Bergamo and Genoa can be deployed simultaneously to address a multitude of workloads to optimize their infrastructure. Bergamo boasts a 2X Cloud Container Density when compared to an EPYC Milan 7763 (64 core and 128 Threads), effectively doubling core and thread count. Bergamo is planned to be released in the 1H 2023.

Edge Computing and Telecom CPU: Siena

Edge computing and telecommunication are at the forefront of development when considering self-driving cars and 5G networking, industry leaders need a solution that offers the best performance for the lowest wattage. AMD is promising Siena will offer a CPU with optimized performance per wattage for a lower TCO. With little details on Siena, we hope to see a strong yet efficient CPU. Siena is set to release in 1H 2023.

AMD Looks to Power the Future

With AMD being a huge powerhouse in the server CPU space, we can expect a lot to be had in the next generation of data center CPUs. New innovations in the CPU space can keep up with the ever-so-increasing power of GPUs and accelerator cards for AI development and HPC. With that said, AMD's EPYC Genoa CPUs for servers offer a huge uplift in performance. The AMD EPYC 9000 Genoa CPU lineup is expected to launch in the second half of this year with Bergamo, Genoa-X, and Siena set to release next year.
