NVIDIA Blackwell Ultra FAQs
NVIDIA Blackwell Ultra is the GPU architecture for the most powerful systems for AI inference available today, including NVIDIA DGX B300 and DGX GB300. Blackwell Ultra systems deliver up to 50x higher throughput per megawatt and up to 35x lower cost per token than NVIDIA Hopper™ for low-latency agentic workloads, through hardware–software codesign, according to SemiAnalysis InferenceX benchmarks (Q1 2026).
Yes. The large memory spaces available with Blackwell Ultra-powered systems enable DeepSeek-R1 (671B MoE) inference on fewer GPUs with lower tensor parallelism overhead. In MLPerf Inference v6.0 (April 2026), systems powered by NVIDIA Blackwell Ultra GPUs delivered the highest throughput across the widest range of models and scenarios. On DeepSeek-R1, Blackwell Ultra systems delivered 2.5 million tokens per second—up to 2.7x higher token throughput compared to Blackwell Ultra debut submissions just six months prior, as a result of NVIDIA TensorRT™-LLM software updates.
NVIDIA Blackwell Ultra delivers AI Inference at $0.24 per million tokens at 102 TPS/user on DeepSeek-R1 using NVIDIA Dynamo TensorRT-LLM and MTP, according to SemiAnalysis InferenceX benchmarks as of April 2026.
