Can I run Gemma 2 27B on AMD Radeon RX 7900 XTX (24GB)?
Yes. Gemma 2 27B runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~18.7 GB of ~23 GB usable).
Runs at Q4_K_M using ~18.7 GB of ~23 GB usable.
That figure is at a 4k context and moves about ±15% as context length changes. AMD Radeon RX 7900 XTX (24GB) leaves ~4.3 GB of headroom.

Running cost · estimate

- Pays for itself after
- ~9,990M tok
At ~$0.15/kWh and the estimated ~37 tok/s, a million generated tokens costs about $0.4 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$999 AMD Radeon RX 7900 XTX (24GB) pays for itself after roughly 9,990 million tokens, so local hardware is mostly a fixed cost, not a per-token one. TDP is the peak draw, so this is an upper bound. Assumptions.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
