Yes — the RX 7600 8GB (8 GB GDDR6) can run gemma-3-1b-it. At Q4 with the default 8K context it needs ≈ 1.75 GB VRAM (weights 0.55 GB + KV cache 0.2 GB + 1 GB runtime overhead), which fits within 8 GB. Decode at Q4/8K: ≈ 183.3 tok/s (estimated, batch 1). FP16 (≈ 3.2 GB) also fits, at ≈ 50.4 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
