Yes. Phi-4 14B fits in fast memory on RTX 3080 12GB at Q4_K_M (10.4 GB needed, 11.5 GB usable), about 60 tok/s (estimate).
Hardware: RTX 3080 12GB · Model: Phi-4 14B
RTX 3080 12GB has 12 GB of VRAM and 912 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. Phi-4 14B (14.7B, Microsoft) at Q4_K_M is a 9.1 GB download and needs 10.4 GB with headroom for about 8k tokens.
