No. Llama 3.3 70B does not fit on RX 7900 XTX 24GB: Q4_K_M needs 47.1 GB and 23.5 GB is usable.
Hardware: RX 7900 XTX 24GB · Model: Llama 3.3 70B
RX 7900 XTX 24GB has 24 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 23.5 GB. Partial offload may also use 60% of that system RAM. Llama 3.3 70B (70.6B, Meta) at Q4_K_M is a 43 GB download and needs 47.1 GB with headroom for about 8k tokens.
