Can I Run DeepSeek-R1-Distill-Qwen-14B on NVIDIA GeForce RTX 4080?
作者： Jakub Rusinowski · 最后更新： 2026年7月12日
Yes, comfortably — DeepSeek R1 Distill Qwen 14B at Q4_K_M needs 10.6 GB at 8K context (8.5 GB weights + 2.1 GB KV cache/overhead), leaving ~5.4 GB of the NVIDIA GeForce RTX 4080's 16 GB, at ~63 tok/s (est.), with room for up to 32K context.
These figures are for DeepSeek-R1-Distill-Qwen-14B, a distill of Qwen2.5-14B — not the full DeepSeek R1. The full DeepSeek R1 (671B) needs about 405 GB of weights at Q4_K_M and is a different model.

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 16 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 4080: 8K 10.6 GB · 32K 14.6 GB · 128K 30.7 GB ✗. Past 128K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
