Yes. Ministral 3 8B fits in fast memory on RTX 5080 16GB at Q8_0 (11.3 GB needed, 15.5 GB usable), about 58 tok/s (estimate).
Hardware: RTX 5080 16GB · Model: Ministral 3 8B
RTX 5080 16GB has 16 GB of VRAM and 960 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 15.5 GB. Partial offload may also use 60% of that system RAM. Ministral 3 8B (8.92B, Mistral) at Q8_0 is a 9.9 GB download and needs 11.3 GB with headroom for about 8k tokens.
