AMD’s latest Epyc processors are making their way into AWS virtual machines. Both regular and HPC instances are now available with Epyc Genoa.

The fourth generation of AMD Epyc processors for the data center appear in new instances of Amazon Web Services. AWS integrates the chips into specialized instances for HPC workloads as well as regular instances for traditional workloads. They are placed alongside alternatives to Intel Xeon Scalable and Graviton.

Hpc7a

If you are looking for a powerful instance, you can turn to Hpc7a now. The Hpc7a instances are available in variants with 24, 48, 96 and 192 vCPUs. The vCPUs are full cores in this context because AWS disables hyperthreading for these instances. So the 192-core virtual machine has not just one, but two AMD Epyc 9654 chips in a dual-socket configuration.

All instances continue with similar specifications. You get 768 GB RAM, 300 Gbps network capacity between nodes and 25 Gbps external bandwidth. The high link speed between nodes is useful for customers who want to spread their workloads across a large cluster of VMs.

M7a

For more classic workloads, the new M7a VMs are geared towards general work. The cloud giant announced earlier this summer that these new instances were coming. AWS claims that the VMs running Epyc Genoa are up to half as fast as similar Epyc Milan variants.

M7a comes in many flavors, ranging from a single vCPU, 4GB of memory, and up to 12.5Gbps network bandwidth (m7a.medium) to m7a.48large with 192 vCPUs, 768 GiB memory, and 50Gbps network bandwidth . For these cases, AWS leaves hyperthreading enabled, so the heaviest VM is likely to be supported with a single AMD Epyc 9654. The largest instance thus requires the full computing power of a server, which is why AWS also offers a bare metal version.

The new instances are available in multiple regions in the US and Ireland in the EU.
