Frequently Asked Questions (Codestral-22B + NVIDIA A100 80GB SXM)
Can NVIDIA A100 80GB SXM (80GB) run Codestral-22B locally?
Yes — NVIDIA A100 80GB SXM (80GB) easily runs Codestral-22B even in full FP16. In 4-bit Q4_K_M, Codestral-22B uses only 16.27 GB of your 80 GB VRAM (20% utilization) at ~93.9 tokens/sec. In full 16-bit precision, it requires 48.14 GB.
How is KV Cache calculated for Codestral-22B?
Codestral-22B uses Dense-GQA with 56 transformer layers, 48 attention heads, and 8 KV heads (head dimension 128). At 8,192 tokens in FP16, KV cache consumes 1.75 GB. Enabling 8-bit KV cache (-ctk q8_0 -ctv q8_0 in llama.cpp or --kv-cache-dtype fp8 in vLLM) cuts this in half to 0.88 GB.
