Ampere is the codename for a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to both the Volta and Turing architectures. It was officially announced on May 14, 2020, and is named after French mathematician and physicist André-Marie Ampère.

Nvidia announced the Ampere architecture GeForce 30 series consumer GPUs at a GeForce Special Event on September 1, 2020. Nvidia announced the A100 80 GB GPU at SC20 on November 16, 2020. Mobile RTX graphics cards and the RTX 3060 based on the Ampere architecture were revealed on January 12, 2021.

Nvidia announced Ampere's successor, Hopper, at GTC 2022, and "Ampere Next Next" (Blackwell) for a 2024 release at GPU Technology Conference 2021.

Architectural improvements of the Ampere architecture include the following:
