Can I run Seed-OSS 36B Instruct on AMD Radeon RX 7900 XTX (24GB)?

Compatibility verdict VRAM threshold engine
Yes, but tight usable speed ~31 tok/s est.

Yes. Seed-OSS 36B Instruct runs on AMD Radeon RX 7900 XTX (24GB) at Q4_K_M (~22.5 GB of ~23 GB usable).

Needs ~22.5 GB Device usable ~23 GB

Fits at Q4_K_M (~22.5 GB of ~23 GB usable) but with little headroom. Close other apps; a smaller context frees a few hundred MB.

That figure is at a 4k context and moves about ±15% as context length changes. AMD Radeon RX 7900 XTX (24GB) leaves ~0.5 GB of headroom.

Running cost · estimate

Power & economics est.
Power draw

Electricity / 1M tokens

Pays for itself after
~49,950M tok

At ~$0.15/kWh and the estimated ~31 tok/s, a million generated tokens costs about $0.48 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 49,950 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.
