Blackwell is a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to Hopper microachitecture and Ada Lovelace microarchitecture.

Named after statistician and mathematician David Blackwell, the Blackwell architecture was leaked in 2022 and B100 & B40 was officially revealed in October 2023 in an official Nvidia roadmap in an official Nvidia investor presentation for investors[1] and was officially announced at Nvidia GTC 2024 keynote on March 18, 2024.[2]
