Yes — the RTX 4090 24GB (24 GB GDDR6X) can run qwen35b-a3b-fable-sft-abliterated. At Q4 with the default 8K context it needs ≈ 20.69 GB VRAM (weights 19.09 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 24 GB. Decode at Q4/8K: ≈ 213.8 tok/s (estimated, batch 1). FP16 needs ≈ 71.0 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	20.39 GB	Yes	213.8 ± est.
Q4	8K default	20.69 GB	Yes	213.8 ± est.
Q4	32K	22.49 GB	Yes	213.8 ± est.
FP16	4K	70.7 GB	No	19.3 ± est.
FP16	8K default	71.0 GB	No	19.2 ± est.
FP16	32K	72.8 GB	No	18.2 ± est.

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).
