HOSTKEY RTX PRO 5000 Blackwell 72 GB Ollama benchmark

HOSTKEY (hostkey.com) own-hardware test of the NVIDIA RTX PRO 5000 Blackwell 72 GB variant, article dated 2026-08-09. The author distinguishes the 72 GB card from the 48 GB base SKU by the PCI id 10de:2bb3 and by the double-sided memory layout, and states the card under test has 72 GB. The LLM table is produced by their own Ollama-based harness, described in the companion Radeon AI Pro R9700 article (hostkey.com/blog/142) as a custom Ollama test that reports average tokens/sec, max context, load time and generation time. The 72 GB article prints four rows: deepseek-r1:14b 67.71 tok/s, deepseek-r1:32b 32.89 tok/s, gpt-oss:20b 149.38 tok/s, qwen3-coder-next 74.34 tok/s, all single card, no offload. Ollama version, the GGUF quant tag, prompt length and generated-token count are NOT printed, so those fields stay null and confidence is held at 0.6. Third party, not a vendor number.
