Can RTX 4090 24GB run gemma-4-E4B-it?

NVIDIA · 24 GB GDDR6X · 1008 GB/s bandwidth · Google · 8.0B · model ctx up to 128K

Yes — the RTX 4090 24GB (24 GB GDDR6X) can run gemma-4-E4B-it. At Q4 with the default 8K context it needs ≈ 7.0 GB VRAM (weights 4.4 GB + KV cache 1.6 GB + 1 GB runtime overhead), which fits within 24 GB. Decode at Q4/8K: ≈ 80.2 tok/s (estimated, batch 1). FP16 (≈ 18.6 GB) also fits, at ≈ 22.0 tok/s (estimated). 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	6.2 GB	Yes	80.2 est.
Q4	8K default	7.0 GB	Yes	80.2 est.
Q4	32K	11.8 GB	Yes	80.2 est.
FP16	4K	17.8 GB	Yes	22.0 est.
FP16	8K default	18.6 GB	Yes	22.0 est.
FP16	32K	23.4 GB	No	66.3 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).
