Yes. DeepSeek R1 Distill Qwen 14B fits in fast memory on RTX 4070 12GB at Q4_K_M (10.3 GB needed, 11.5 GB usable), about 34 tok/s (estimate).
Hardware: RTX 4070 12GB · Model: DeepSeek R1 Distill Qwen 14B
RTX 4070 12GB has 12 GB of VRAM and 504 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 11.5 GB. Partial offload may also use 60% of that system RAM. DeepSeek R1 Distill Qwen 14B (14.8B, DeepSeek) at Q4_K_M is a 9 GB download and needs 10.3 GB with headroom for about 8k tokens.
