Quick Hardware Verdict

H800 80GB SXM (80GB physical, 76 GiB usable) runs 4-bit (Q4_K_M) DeepSeek R1 Distill Llama 70B at 8K context using 43.32 GiB with 32.68 GiB of safe headroom (~48.8 tok/s single-stream decode).

KV Cache & Runtime Tuning

DeepSeek R1 Distill Llama 70B uses Dense GQA (70.55B total, 70.55B active per token). Moving from 8K to 32K context expands FP16 KV cache from 2.5 GiB to 10 GiB; enabling 8-bit KV cache (llama.cpp -ctk q8_0 -ctv q8_0 or vLLM --kv-cache-dtype fp8) saves 5 GiB at 32K (reducing total VRAM to 45.82 GiB).

VRAM Scaling Across Context Windows (4K to 128K, 4-bit Weights)

Model weights remain constant while attention KV cache grows with context length and batch size.
