WHAT IS THE B300

The B300 (Blackwell Ultra) is NVIDIA's inference-first Blackwell refresh: 288 GB of HBM3e - half again the B200's memory - with FP4 throughput tuned for reasoning models that generate long chains of thought. It targets the largest serving deployments; training fleets stay on B200-class parts.
