High frequency profiles - Gen 4

The high frequency profile family provides access to CPUs with elevated clock speeds that are tailored for compute-intensive workloads. These workloads include Electronic Design Automation (EDA), Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and weather or climate modeling. These higher frequencies boost per-core performance, by enabling faster execution, and more efficient use of software licensed on a per-core basis.

AMD hx4da instance profiles

The AMD® hx4da accelerated virtual server profiles are built atop AMD® 5th Generation Epyc 9575F. This processor offers all-core boost speeds up to 4.5 GHz and a max turbo speed of 5 GHz. AMD® 5th Generation Epyc 9575F processor is a Chiplet-based architecture and uses distributed L3 cache. Distributed L3 cache can ensure more dedicated L3 per CPUs.

Gen 4 High Frequency profiles are available in the Dallas (us-south) and Sydney (au-syd) regions with the AMD 5th Generation Epyc 9575F processor-base to provision virtual server instances.

Limits

  • If you enable and then disable secure boot, the machine type and the PCI or PCIe alignment changes. For more information, see Secure boot for Virtual Servers for VPC.
  • Second-generation boot volumes with the sdp profile do not support secure boot.

Boot volume profiles

For Block Storage for VPC, only first-generation volumes from the tiered and custom volume profile families can be used as boot volumes for hx4da instances.
