Perplexity research shows NVIDIA GB200 excels at LLM inference

Perplexity has published research detailing how they serve large language models, specifically Qwen3 235B, on NVIDIA's GB200 NVL72 Blackwell racks. The findings indicate that the GB200 platform offers significant improvements over previous NVIDIA hardware for large-model inference, boasting reduced latency and higher throughput. This research highlights the GB200's capabilities for both training and high-throughput inference, particularly for Mixture-of-Experts (MoE) models. AI

IMPACT NVIDIA's GB200 Blackwell platform shows significant gains in LLM inference speed and cost-efficiency, potentially accelerating deployment of large models.

    The benchmarks show the gap. NVLS all-reduce latency drops from 586.1µs on H200 to 313.3µs on GB200. In MoE prefill at EP=4, combine falls from 730.1µs to 438.5

    We published new research on how we serve post-trained Qwen3 235B models on NVIDIA GB200 NVL72 Blackwell racks.

    We published new research on how we serve post-trained Qwen3 235B models on NVIDIA GB200 NVL72 Blackwell racks. GB200 is a major step up over Hopper for high-throughput inference on large MoE models, not just a training platform. https://t.co/yYZuPRXWzr
