NVIDIA A800 PCIe 80GB

80 GB HBM2e · 5120-bit · 6,912 cores

The NVIDIA A800 PCIe 80GB is a data center accelerator built on the same Ampere GA100 silicon as the A100, introduced in November 2022 for the Chinese market as an export-compliant counterpart with unchanged compute performance. Chip-to-chip NVLink bandwidth is reduced versus the A100, and the PCIe card bridges at most two GPUs. Multi-Instance GPU splits the board into as many as seven isolated 10 GB instances for workload isolation.
