Nvidia BlueField is a line of data processing units (DPUs) designed and produced by Nvidia. Initially developed by Mellanox Technologies, the BlueField IP was acquired by Nvidia in March 2019, when Nvidia acquired Mellanox Technologies for US$6.9 billion. The first Nvidia produced BlueField cards, named BlueField-2, were shipped for review shortly after their announcement at VMworld 2019, and were officially launched at GTC 2020. Also launched at GTC 2020 was the Nvidia BlueField-2X, an Nvidia BlueField card with an Ampere generation graphics processing unit (GPU) integrated onto the same card. BlueField-3 and BlueField-4 DPUs were first announced at GTC 2021, with the tentative launch dates for these cards being 2022 and 2024 respectively.
Nvidia BlueField cards are targeted for use in datacenters and high performance computing, where latency and bandwidth are important for efficient computation.
BlueField cards differ from network interface controllers in their offloading of functions that would normally be reserved for the CPU, and the presence of CPU cores (typically ARM or MIPS based) and memory support (typically DDR4, though Bluefield-3's release brought...
