GPU sizing for Llama 3.1 70B inference: numbers from benchmarks
8 min · May 26, 2026
How many GPUs does it really take to run Llama 3.1 70B in-house? Concrete configs (A100, H100, H200), the impact of quantization (FP16 → FP8 → INT4), tokens/s, TTFT, and cost per 1M tokens. No marketing — numbers from vLLM and TensorRT-LLM benchmarks.
