Can I Run DeepSeek R1 (671B) on NVIDIA GeForce RTX 4060 Ti 16GB?
Written by Jakub Rusinowski · Last updated July 12, 2026
No. DeepSeek R1 (671B) needs 406.5 GB at 8K context (405.1 GB weights + 1.4 GB KV cache/overhead) at Q4_K_M and the NVIDIA GeForce RTX 4060 Ti 16GB has only 16 GB. No quantization we publish closes a gap that size.

DeepSeek R1 (671B) on the NVIDIA GeForce RTX 4060 Ti 16GB: VRAM by quantization

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 4060 Ti 16GB: 8K 406.5 GB ✗ · 32K 408.2 GB ✗ · 128K 415.1 GB ✗. Past 8K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
