Ampere (microarchitecture)

Ampere is the codename for a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to both the Volta and Turing architectures, officially announced on May 14, 2020. It is named after French mathematician and physicist André-Marie Ampère. Nvidia announced the next-generation GeForce 30 series consumer GPUs at a GeForce Special Event on September 1, 2020. Nvidia announced A100 80GB GPU at SC20 on November 16, 2020. Mobile RTX graphics cards and the RTX 3060 were revealed on January 12, 2021. Nvidia also announced Ampere's successors, tentatively codenamed "Ampere Next" for a 2022 release and "Ampere Next Next" for a 2024 release at GPU Technology Conference 2021.

A100 accelerator and DGX A100.
Announced and released on May 14, 2020 was the Ampere-based A100 accelerator. The A100 features 19.5 teraflops of FP32 performance, 6912 CUDA cores, 40GB of graphics memory, and 1.6TB/s of graphics memory bandwidth. The A100 accelerator was initially available only in the 3rd generation of DGX server, including 8 A100s. Also included in the DGX A100 is 15TB of PCIe gen 4 NVMe storage, two 64-core AMD Rome 7742 CPUs, 1 TB of RAM, and Mellanox-powered HDR InfiniBand interconnect. The initial price for the DGX A100 was $199,000.
