Frequently Asked Questions (DeepSeek-R1-Distill-Qwen-7B + NVIDIA RTX 4070 Ti Super)
Can NVIDIA RTX 4070 Ti Super (16GB) run DeepSeek-R1-Distill-Qwen-7B locally?
Yes — NVIDIA RTX 4070 Ti Super (16GB) can run DeepSeek-R1-Distill-Qwen-7B using FP8 (W8A8 / E4M3). Full FP16 (16.79 GB) exceeds 16 GB VRAM, but 4-bit GGUF Q4_K_M / AWQ requires 5.85 GB (4.76 GB weights + 0.44 GB KV cache at 8K context), delivering ~90.2 tokens/sec.
How is KV Cache calculated for DeepSeek-R1-Distill-Qwen-7B?
DeepSeek-R1-Distill-Qwen-7B uses Dense-GQA with 28 transformer layers, 28 attention heads, and 4 KV heads (head dimension 128). At 8,192 tokens in FP16, KV cache consumes 0.44 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 0.22 GB.
