Yes. Gemma 3n E4B (on-device) fits in fast memory on RX 7900 XTX 24GB at Q8_0 (10.5 GB needed, 23.5 GB usable), about 61 tok/s (estimate).
Hardware: RX 7900 XTX 24GB · Model: Gemma 3n E4B (on-device)
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. Gemma 3n E4B (on-device) (8B, Google) at Q8_0 is a 9.5 GB download and needs 10.5 GB with headroom for about 8k tokens.
