GIGABYTE G893-ZD1-AAX5 HGX B200 8-GPU Server

HGX B200 is NVIDIA's 8-GPU Blackwell building block: eight B200 SXM GPUs and the NVSwitch fabric joining them, supplied to manufacturers like Gigabyte who engineer complete servers around it. The physical changes against Hopper: each B200 is a dual-die package with 208 billion transistors, memory rises to 180GB of HBM3e per GPU at roughly 8 TB/s, NVLink doubles to 1.8 TB/s per GPU, and the second-generation Transformer Engine adds FP4 precision with micro-tensor scaling.

1,440GB of pooled HBM3e, 64 TB/s of aggregate memory bandwidth, 144 petaFLOPS of FP4 compute, and 14.4 TB/s of NVLink fabric through NVSwitch. In workload terms: full-precision fine-tuning of models in the low hundreds of billions of parameters, real-time FP4 serving of trillion-parameter-class models, and long-context inference with KV cache headroom beyond any Hopper node.

Three situations. Inference fleets at frontier scale, where FP4 roughly doubles tokens per watt and NVIDIA cites up to 15x real-time trillion-parameter inference against the H100 generation. Training programs where the doubled fabric and 60 percent bandwidth gain compress timelines with business value. And workloads already pressing the H200's 141GB per-GPU ceiling. Teams fine-tuning 70B-class models or serving within the Hopper envelope are usually better served by the Lenovo or ASUS HGX H200 systems, and MillionMiner will model both in the quote.

Usable, with engineering. The second-generation Transformer Engine implements micro-tensor scaling, tracking quantization scale at fine granularity so four-bit weights hold accuracy that naive quantization loses. Production serving stacks including TensorRT-LLM support it, and inference of large models is where it pays: memory footprint halves against FP8 and throughput roughly doubles. Training still runs FP8 and BF16; FP4 is an inference economics lever, and a large one at fleet scale.

Yes, that is the engineering premise of this Gigabyte platform: an 8U chassis with the airflow volume to hold the full HGX B200 complex at specification without direct liquid cooling. The practical consequence is deployment freedom, since no coolant distribution, plumbing, or liquid-loop maintenance is required and any data center with adequate power and conventional cooling qualifies. MillionMiner confirms the airflow and inlet temperature requirements for your site during the quote.

Core density and memory bandwidth. The EPYC 9005 series reaches 192 cores per socket, which feeds preprocessing-heavy pipelines for eight GPUs of this class, and the platform runs twelve DDR5 channels per processor with the twenty-four modules populated one per channel, the layout that sustains full bandwidth. The PCIe Gen5 lane budget also carries the one-adapter-per-GPU networking topology without compromise. The 9004 series remains available for teams standardized on it.

The boundary is the NVLink domain. This node joins eight GPUs in one coherent fabric; the GB200 class joins 72 at rack scale, with liquid cooling and facility engineering to match. If your training parallelism genuinely needs more than eight GPUs in a single domain, rack-scale is the answer. For everything that fits eight Blackwell GPUs, which covers most enterprise training and nearly all inference serving, this node delivers the same generation without the facility project, and scales outward over InfiniBand instead.

Through the one-adapter-per-GPU topology the PCIe layout is built for: eight single-slot positions take 400 Gb/s adapters on NVIDIA Quantum-2 InfiniBand or Spectrum-X Ethernet, giving GPUDirect RDMA a dedicated fabric port per GPU so gradients move between nodes without touching the CPU. Four additional dual-slot positions carry storage and management networking. MillionMiner advises on switch and fabric design when a deployment grows past one machine.

Twelve 3000W 80 PLUS Titanium supplies in a 6+6 redundant arrangement define the envelope, with the GPU complex alone capable of drawing eight kilowatts under sustained load before the host is counted. This is squarely a data center machine. MillionMiner confirms the exact draw of your specified configuration during the quote, and hosting in MillionMiner's own facilities is available for teams that prefer not to provision rack power at this scale.

Submit your workload, scale, and deployment details through the quote form. A MillionMiner specialist confirms configuration, destination eligibility under the US export controls that apply to Blackwell-class accelerators, and the delivery plan. Every system is tested before shipment and delivered worldwide DDP with duties and customs handled. Rack integration guidance and hosted deployment are both available.
