Qwen3-8B inference benchmark and FP8 on Blackwell
Independent benchmarks compare Qwen3-8B inference on an RTX PRO 6000 Blackwell (96 GB) across three serving stacks (vLLM 0.27.1, SGLang 0.5.9, and llama.cpp CUDA). At concurrency 32 using BF16, vLLM achieved 1,725 aggregate tokens/s (TTFT p50 39 ms), SGLang 1,327 tok/s (TTFT p50 42 ms), and llama.cpp 428 tok/s (TTFT p50 316 ms). Applying an FP8 checkpoint to vLLM increased throughput by ~1.5x (aggregate 1,725 -> 2,597 tok/s; single-stream 86 -> 130 tok/s) with lower latency and no detected regressions on a fixed factual check. The author documents methodology, reproductions, and an sm_120-specific kernel workaround required to run FP8 on workstation Blackwell hardware.
- GPU used: RTX PRO 6000 Blackwell, 96 GB (workstation Blackwell, sm_120).
- Model benchmarked: Qwen3-8B across vLLM 0.27.1, SGLang 0.5.9, and llama.cpp (CUDA).
- BF16, concurrency 32 aggregate throughput: vLLM 1,725 tok/s; SGLang 1,327 tok/s; llama.cpp 428 tok/s.
