Frequently Asked Questions (Qwen2.5-Coder-32B-Instruct + NVIDIA RTX 4070 Ti Super)
Can NVIDIA RTX 4070 Ti Super (16GB) run Qwen2.5-Coder-32B-Instruct locally?
No — A single NVIDIA RTX 4070 Ti Super (16GB) cannot fit Qwen2.5-Coder-32B-Instruct in VRAM. Even in 4-bit Q4_K_M, Qwen2.5-Coder-32B-Instruct requires 23.14 GB VRAM (2x NVIDIA RTX 4070 Ti Super GPUs needed for full VRAM execution, or heavy CPU RAM offloading at ~2.7 tok/s).
How is KV Cache calculated for Qwen2.5-Coder-32B-Instruct?
Qwen2.5-Coder-32B-Instruct uses Dense-GQA with 64 transformer layers, 40 attention heads, and 8 KV heads (head dimension 128). At 8,192 tokens in FP16, KV cache consumes 2 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 1.00 GB.
