NVIDIA Data Center GPU H100 SXM5 80GB
The NVIDIA H100 SXM5 80GB is the premier enterprise supercomputing accelerator built on the Hopper architecture (GH100 silicon). Featuring 80GB of ultra-fast HBM3 memory delivering 3.35 TB/s bandwidth, 4th-generation Tensor Cores with a dedicated Transformer Engine, and 4th-generation NVLink providing 900 GB/s bidirectional throughput, it delivers up to 6x higher throughput for large language model pre-training compared to the A100. Operating at up to 700W TDP, it forms the compute backbone of modern AI supercomputers and HGX 8-way platforms. Secondary market buyers should verify SXM5 gold pad cleanliness, check torque tensioning history on heatsink mounting brackets, and confirm enterprise VBIOS version.
