Can RTX 5090 32GB run gemma-4-26B-A4B-it?

NVIDIA · 32 GB GDDR7 · 1792 GB/s bandwidth · Google · 25.2B (active 3.8B) · MoE · model ctx up to 256K

Yes — the RTX 5090 32GB (32 GB GDDR7) can run gemma-4-26B-A4B-it. At Q4 with the default 8K context it needs ≈ 15.62 GB VRAM (weights 13.86 GB + KV cache 0.76 GB + 1 GB runtime overhead), which fits within 32 GB. Decode at Q4/8K: ≈ 300.1 tok/s (estimated, batch 1). FP16 needs ≈ 52.16 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	15.24 GB	Yes	300.1 est.
Q4	8K default	15.62 GB	Yes	300.1 est.
Q4	32K	17.9 GB	Yes	300.1 est.
FP16	4K	51.78 GB	No	90.1 est.
FP16	8K default	52.16 GB	No	88.7 est.
FP16	32K	54.44 GB	No	81.5 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).
