Hardware: RX 7800 XT 16GB · Model: Bonsai 2 2B (ternary)
RX 7800 XT 16GB has 16 GB of VRAM and 624 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. Bonsai 2 2B (ternary) (2B, Prism ML) at Q2_0 is a 0.91 GB download and needs 2 GB with headroom for about 8k tokens.
