The Gigabyte NVIDIA A100 SXM4 80GB GPU Module (MPN: 900-21020-0020-000) is a high-performance compute accelerator built on NVIDIA's Ampere architecture, designed to meet the demanding requirements of modern AI training, high-performance computing (HPC), and large-scale data analytics workloads. Utilizing the SXM4 form factor, it connects via NVIDIA's NVLink and NVSwitch interconnect fabric, enabling multi-GPU configurations with substantially higher bandwidth than PCIe-based alternatives. The 80GB HBM2e memory subsystem delivers 2TB/s of memory bandwidth, making it well-suited for memory-intensive models and datasets that cannot be accommodated by lower-capacity accelerators.
The A100 SXM4 80GB is built around 6,912 CUDA cores and 432 third-generation Tensor Cores, which accelerate mixed-precision matrix operations central to deep learning frameworks including TensorFlow, PyTorch, and MXNet. The module supports TF32, FP64, FP32, FP16, BF16, and INT8 precisions, providing flexibility across scientific simulation, inference optimization, and training pipelines. Multi-Instance GPU (MIG) technology allows the physical GPU to be partitioned into as many as seven independent GPU instances, each with dedicated memory, cache, and compute resources, enabling secure and efficient resource sharing across multiple concurrent workloads or tenants.
As an SXM4 form factor module, this unit is intended for installation into compatible server platforms such as the NVIDIA HGX A100 baseboard or qualified server systems that support the SXM4 socket. It interfaces with NVLink 3.0 for up to 600GB/s bidirectional GPU-to-GPU bandwidth in multi-GPU topologies. The module is a foundational building block for AI supercomputing clusters, large language model (LLM) training infrastructure, genome sequencing pipelines, and financial risk simulation environments deployed across enterprise datacenters, cloud service providers, and research institutions.

Reference servers include Dell PowerEdge XE9680 / XE9712, HPE Cray XD670, Lenovo ThinkSystem SR685a / SR675 V3, Supermicro AS-A21GE / SYS-821GE, Gigabyte G593 / G894, ASUS ESC. Share your target platform in the RFQ and we will confirm chassis-to-GPU compatibility and recommended NIC pairing.
Highly model-dependent. L40S / RTX-class: typically 3-6 weeks. H100/H200/B200 in SXM form factor: 12-16 weeks for whole-platform allocations. We quote genuine-channel ETAs only — no grey-market promises.
Yes — Omnixon stocks the full NVIDIA networking lineup (Quantum-2 / Quantum-X InfiniBand, Spectrum-X Ethernet, ConnectX NICs, BlueField DPUs) so we can quote a complete training-cluster BOM, not just the GPUs.
Yes. We hold genuine-channels for NVIDIA AI Enterprise software subscriptions. Add it to your RFQ and we quote node-aligned licensing along with the hardware.
