AWS announces the availability of bmn-cx3a instances on second-generation AWS Outposts racks. Bmn-cx3a instances feature 5th Gen AMD EPYC processors with a maximum frequency of 4.1 GHz and NVIDIA ConnectX-7 (CX7) network interface cards, delivering up to 800 Gbps of bare-metal accelerated network bandwidth operating at near line rate. Bmn-cx3a instances offer up to 256 cores and 1.5 TB of memory across two sizes, bmn-cx3a.metal-32xl and bmn-cx3a.metal-64xl, with 2x 8 TB NVMe SSD storage. With native Layer 2 (L2) multicast and hardware Precision Time Protocol (PTP) support, bmn-cx3a instances a

Why this matters
Why now

The continuous demand for higher-performance compute at the edge necessitates constant upgrades in hardware offerings, especially in areas requiring accelerated networking and bare-metal access.

Why it’s important

This release signifies AWS's commitment to delivering cutting-edge hardware to on-premises Outposts, directly addressing critical workloads requiring high-bandwidth, low-latency computing closer to data sources.

What changes

Customers can now deploy AMD-based instances on Outposts with significantly higher networking speeds and core counts, enabling more demanding applications to run locally with bare-metal performance characteristics.

Winners
  • · AWS
  • · AMD
  • · NVIDIA
  • · Enterprises with edge computing requirements
Losers
  • · Other on-premise hardware providers
  • · Alternative edge computing solutions
Second-order effects
Direct

Increased adoption of AWS Outposts by enterprises with demanding on-premises compute needs, especially those for AI/ML inference or high-performance data processing.

Second

Accelerated development of edge-native applications and services that previously faced performance constraints on Outposts.

Third

Potential for closer integration between cloud and on-premises AI/HPC workloads, blurring the lines between traditional data centers and hyperscale cloud infrastructure.
