Llama 3 70B (Q8)

Meta Llama 3 70B Instruct, Q8_0 GGUF, batch 1, 4K context.

Primary metric: Tokens / sec (tok/s)

Reference prompts

Representative prompts for this workload. Exact prompts and harness settings still depend on the cited source for each record.

  • Prompt 1

    A train leaves station A at 9:00 going 60 mph. Another leaves station B (180 miles away) at 9:30 going 80 mph toward A. When do they meet? Show your work.

  • Prompt 2

    If a 70B-parameter model uses ~140GB at FP16, what is its likely memory footprint at Q4_K_M? Show the arithmetic.

  • Prompt 3

    Walk through which of these is cheaper for 10M tokens/day at 30 days: H100 cloud at $2/hr vs RTX 4090 owned at $1600 + $0.10/kWh.

  • Prompt 4

    Explain step-by-step why FP8 inference can be 2x faster than FP16 on H100 but not on A100.

  • Prompt 5

    Given a 4-bit quantized Llama 3 70B model at ~40GB, how much VRAM headroom is needed for KV cache at 8K context, batch 1?

Reference runtime command

A representative invocation for reproducing this workload class. Source-specific runs may use adjacent runtimes unless the record says otherwise.

shell
llama-server -m llama-3-70b-instruct.Q8_0.gguf -c 4096 -ngl 999 --seed 42

Single batch. Q8_0 (~75GB). Often requires multi-GPU or partial CPU offload. Median of 5 runs.
