NVIDIA Data Center GPU A100 SXM4 80GB
The NVIDIA A100 SXM4 80GB is an ultra-high-bandwidth mezzanine GPU accelerator built on the Ampere GA100 architecture. Designed specifically for dense HGX 4-way and 8-way supercomputing clusters, it features 80GB of HBM2e memory delivering 2.039 TB/s bandwidth and connects to neighboring GPUs via 3rd-generation NVLink at 600 GB/s bidirectional throughput. Operating at 400W TDP, it unleashes maximum performance for massive transformer pre-training, large language model fine-tuning, and high-performance physics simulations. On the secondary market, SXM4 modules are among the most sought-after compute units; buyers must ensure gold pad contacts on the SXM mezzanine connector are unblemished and verify board serial pairing.
