Can RX 9070 XT 16GB run Ornith-1.0-35B?

AMD · 16 GB GDDR6 · 640 GB/s bandwidth · DeepReinforce · 35.0B (active 3.0B) · MoE · model ctx up to 256K

No — Ornith-1.0-35B at Q4 needs ≈ 20.55 GB even at 4K context, beyond the RX 9070 XT 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 228.4 tok/s (estimated, batch 1). FP16 needs ≈ 71.6 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	20.55 GB	No	235.1 est.
Q4	8K default	20.85 GB	No	228.4 est.
Q4	32K	22.65 GB	No	193.6 est.
FP16	4K	71.3 GB	No	—
FP16	8K default	71.6 GB	No	—
FP16	32K	73.4 GB	No	—

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).
