Can I run SmolLM2 360M on AMD Radeon RX 7900 XTX (24GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~2303 tok/s est.

Yes. SmolLM2 360M runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~1.2 GB of ~23 GB usable).

Needs ~1.2 GB Device usable ~23 GB

Runs at Q4_K_M using ~1.2 GB of ~23 GB usable. You have room for FP16 for higher quality.

That figure is at a 4k context and moves about ±15% as context length changes. AMD Radeon RX 7900 XTX (24GB) leaves ~21.8 GB of headroom, room to step up to FP16 for higher quality.

Pays for itself after
~2,039M tok

At ~$0.15/kWh and the estimated ~2303 tok/s, a million generated tokens costs about $0.01 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 2,039 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.
