HOSTKEY: RTX PRO 5000 72GB Blackwell, qwen3-coder-next, Ollama, avg decode

Per-request decode tok/s, one request at a time (the table reports a single average tokens/sec, not an aggregate across concurrent requests). HOSTKEY own-hardware test, article dated 2026-08-09, of one NVIDIA RTX PRO 5000 Blackwell 72 GB (PCI id 10de:2bb3, double-sided memory) in a Ryzen 9 7950X host, 128 GB DDR5, Ubuntu 24.04, Ollama. Model is the Ollama tag qwen3-coder-next. Qwen3-Coder-Next pulled as the Ollama tag qwen3-coder-next; the page notes the model is about 51 GB. Ollama version, the GGUF quantization tag, the prompt length and the number of generated tokens are NOT stated on the page, so format_id is null and no prompt or output length is asserted. The companion R9700 article (hostkey.com/blog/142) describes the same harness: a custom Ollama test reporting average tokens/sec, max context, load time and generation time.

First published measurement found for nvidia-rtx-pro-5000-72gb-blackwell, which previously had zero benchmark records. The page also prints a max-context column and a load-time column; those are not filed because neither is a metric this record type measures. Do not read this number as comparable to the Hardware Corner llama-bench tables for the 48 GB SKU: different engine, unstated quant, unstated context depth.
