Bow-2000
NEWThe Bow-2000 machine is the building block for our Bow Pod systems and for disaggregated machine intelligence infrastructure at scale.
Each 1U blade features 4 Bow IPU processors, and delivers an amazing 1.4 petaFLOP of AI compute, 3.6GB In-Processor-Memory™ and up to 256GB Streaming Memory™.
Can be run independently or when combined with host servers the Bow-2000 technology is at the heart of all Graphcore Bow Pod systems.
