Supermicro AS-A126GS-TNBR-G1-OTO-3 rack server Dual EPYC 9575F 64-core 3.3 GHz 8 GPU

Dual EPYC 9575F GPU server

The Supermicro AS-A126GS-TNBR-G1-OTO-3 is a rack-mounted server system built around two AMD EPYC 9575F processors. Each CPU delivers 64 cores and 128 threads at 3.3 GHz with 256 MB cache. The platform targets organisations running large-scale AI training, high-performance computing or dense virtualisation workloads that demand maximum parallel throughput.

Air-cooled SXM GPU density

Eight onboard SXM GPU accelerators are cooled by air inside a single chassis, removing the need for external liquid infrastructure. Storage access comes from eight front hot-swap 2.5" NVMe bays plus two hot-swap 2.5" SATA bays. Networking uses dual 10G ports based on the X710 controller, while management runs through a dedicated IPMI interface. Expansion includes 10 PCIe 5.0 x16 slots split between low-profile and full-height half-length form factors.

Memory capacity and upgrade path

The board provides 24 DIMM slots supporting 6400 MT/s DDR5 up to 6 TB total when populated at one DIMM per channel. This configuration suits buyers who need maximum memory bandwidth per core rather than absolute capacity beyond 6 TB. The dual EPYC 9004/9005 series socket design allows processor upgrades within the same generation family, extending service life for clusters that standardise on this socket platform.
