The NVIDIA A100 80GB PCIe is the higher-memory PCIe version of NVIDIA's Ampere-generation data center GPU (GA100), supplied as the PNY kit NVA100TCGPU80-KIT. It carries 80 GB of HBM2e memory with ECC and about 1.9 TB/s of bandwidth, according to NVIDIA's specification.
The card connects over PCIe 4.0 x16, has a maximum power of 300 W and is a dual-slot passive design, so it needs a server with directed airflow. Multi-Instance GPU (MIG) can split one card into up to seven isolated instances. The A100 is still widely used for AI training and inference and for HPC in existing PCIe servers. Check your server's qualified GPU list before ordering.
