Hardware: RTX 3080 10GB · Model: Phi-4 14B

RTX 3080 10GB has 10 GB of VRAM and 760 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 9.5 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.
