A100 SXM GPU

The NVIDIA A100 SXM is a data center GPU based on the Ampere architecture, representing NVIDIA's previous-generation offering before the newer H100 and GB300 series. Built on a 7nm manufacturing process, the A100 SXM delivers substantial computational power with 80GB of HBM2e memory and 6,912 CUDA cores alongside 432 third-generation Tensor Cores. The SXM form factor enables higher power delivery at 400W TDP compared to PCIe variants, supporting more demanding workloads in server environments. Key technical specifications include 2,039 GB/s of memory bandwidth through a 5,120-bit memory interface, 312 TFLOPS of FP16 performance, and 624 TOPS for INT8 operations. The A100 SXM incorporates Multi-Instance GPU (MIG) technology, allowing partitioning into up to seven independent GPU instances, and supports TF32 precision for enhanced AI training efficiency. NVLink connectivity provides high-speed inter-GPU communication for multi-GPU configurations. In cloud deployments, the A100 SXM serves AI training workloads, deep learning inference, and high-performance computing applications that require substantial memory capacity and computational throughput. The 80GB memory configuration accommodates large language models and complex datasets, while MIG capability enables multi-tenant scenarios where GPU resources need isolation and dedicated allocation.
