Can I run LFM3 Omni 2B on AMD Radeon RX 9070 XT (16GB)?

Compatibility verdict VRAM threshold engine
Yes, it runs GPU accelerated ~218 tok/s est.

Yes. LFM3 Omni 2B runs on AMD Radeon RX 9070 XT (16GB) at Q4_K_M (~3.1 GB of ~15 GB usable).

Needs ~3.1 GB Device usable ~15 GB

Runs at Q4_K_M using ~3.1 GB of ~15 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 9070 XT (16GB) leaves ~11.9 GB of headroom, room to step up to FP16 for higher quality.

Electricity / 1M tokens

Pays for itself after
~1,361M tok

At ~$0.15/kWh and the estimated ~218 tok/s, a million generated tokens costs about $0.06 in electricity. Versus a hosted API at ~$0.5 per million tokens, the ~$599 AMD Radeon RX 9070 XT (16GB) pays for itself after roughly 1,361 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.
