Can the RTX PRO 6000 Blackwell 96GB Run Llama 3.1 70B?

Runs

Yes. Llama 3.1 70B at Q4_K_M is a 42.5 GB download (Hugging Face file listing for bartowski/Meta-Llama-3.1-70B-Instruct-GGUF), and the RTX PRO 6000 Blackwell 96GB has 96 GB of VRAM, leaving about 53.5 GB for the KV cache and runtime. Published runs put generation at a median of 28.8 tokens per second across 2 cited measurements. Fastest cited run: llm-tracker.

More about this pair

How much VRAM does Llama 3.1 70B need?

The Q4_K_M file is 42.5 GB. Add roughly 1.5 GB for the runtime and an ~8K-token context, so about 44 GB of VRAM holds it comfortably. Longer contexts grow the KV cache and need more.

What speed does Llama 3.1 70B reach on the RTX PRO 6000 Blackwell 96GB?

The fastest published run is 30.5 tokens per second (llm-tracker, Q4_K_M, llama.cpp); the median of 2 cited runs is 28.8 tok/s. Generation reads every weight once per token, so the RTX PRO 6000 Blackwell 96GB's 1792 GB/s of memory bandwidth divided by the 42.52 GB file puts the theoretical ceiling near 42 tokens per second. That is an upper bound, not a speed estimate: kernel, launch and compute overhead keep real runs below it, and SpecPicks rejects any published figure above it.

How the checks work

The fit is the Q4_K_M file size against the card's VRAM, with 1.5 GB kept for the runtime and an ~8K context. A published run counts only if the pair fits, the run is Q4-class, its source does not call it an estimate, it is under the bandwidth ceiling (memory bandwidth ÷ GB read per token: the whole file for a dense model, only the active experts' weights for a mixture-of-experts model such as gpt-oss-20b or Qwen3 30B-A3B, which is why those can post figures above bandwidth ÷ file size), it is not slower than the same card on a model twice its size, a single run is not slower than the same card on a larger dense model, and it is not one figure pasted across many cards.
