Supermicro AS-8126GS-NB3RT NVIDIA HGX B300 8-GPU AI Server – 8U, Dual AMD EPYC 9005, Gold Series

The Supermicro AS-8126GS-NB3RT pairs the NVIDIA HGX B300 8-GPU board with two AMD EPYC 9005 processors in an 8U air-cooled chassis. Its Gold Series version, AS-8126GS-NB3RT-01-G2, is a complete ready-to-deploy inference node: two EPYC 9575F CPUs, 3 TB of DDR5-6400, 61 TB of local NVMe, eight 800G ConnectX-8 ports and two dual-port 200G adapters – rack it, connect power and networking and start serving models.

With 288 GB of HBM3e per GPU and Blackwell Ultra's doubled attention performance, it is built for large-scale LLM inference, reasoning models and retrieval-augmented generation with big local datasets. Mineshop.eu supplies the Gold preset or a custom build with EU delivery and B2B invoicing.

NVIDIA HGX B300 8-GPU performance

System-level figures published by NVIDIA for the eight-GPU board; real application performance depends on model, precision and software.

Gold Series presets – faster delivery

Supermicro Gold Series systems are pre-configured and pre-tested best-sellers with key components already installed, which shortens lead times. For HGX systems the GPU allocation still applies – current lead time to Europe is about 6–12 weeks.

Frequently asked questions

What is the price of the Supermicro AS-8126GS-NB3RT?

We quote the AS-8126GS-NB3RT per configuration – the fully-loaded Gold preset (-01-G2) or a custom build. HGX B300 pricing moves with GPU allocation, so you receive a written B2B quote, excluding VAT, within 1 business day of your request.

What is included in the AS-8126GS-NB3RT-01-G2 Gold Series preset?

Two AMD EPYC 9575F CPUs (128 cores in total), 3 TB DDR5-6400, eight 7.68 TB E1.S NVMe drives, two 1.92 TB M.2 NVMe boot drives, eight 800G ConnectX-8 ports, two dual-port 200G adapters and six 6600 W Titanium power supplies – pre-installed and pre-tested.

Is the AS-8126GS-NB3RT better than the SYS-822GS-NB3RT?

Both use the same HGX B300 8-GPU board and 8U chassis. Choose the AS-8126GS-NB3RT for AMD EPYC 9005 hosts and the storage-heavy Gold preset; choose the SYS-822GS-NB3RT for Intel Xeon 6700P hosts, up to 8 TB of memory (32 DIMMs) and RHEL AI certification.

How fast can it be delivered?

The Gold Series preset currently has the shortest lead time – about 6–12 weeks to Europe. Custom builds can take up to ~30 weeks depending on GPU allocation. Your quote confirms the date.

What does it need in the data centre?

A 200–240 V supply for six 6600 W Titanium PSUs (3+3), 8U in a rack at least 1200 mm deep, a rack rated for 119 kg and 10–35 °C inlet air. Power budget, cords and optics are listed in the quote.

Can you deliver several servers as a cluster?
