Can RTX 4090 24GB run DeepSeek-V4-Pro?

NVIDIA · 24 GB GDDR6X · 1008 GB/s bandwidth · DeepSeek · 861.6B (active 49B) · MoE · model ctx up to 1000K

No — DeepSeek-V4-Pro at Q4 needs ≈ 479.78 GB even at 4K context, beyond the RTX 4090 24GB's 24 GB GDDR6X. It would only run with heavy CPU/disk offload. FP16 needs ≈ 1734.0 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. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	479.78 GB	No	—
Q4	8K default	484.68 GB	No	—
Q4	32K	514.08 GB	No	—
FP16	4K	1729.1 GB	No	—
FP16	8K default	1734.0 GB	No	—
FP16	32K	1763.4 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).

VRAM breakdown at 8K context

Quant	Weights	KV cache	Overhead	Total needed	RTX 4090 24GB VRAM
Q4	473.88 GB	9.8 GB	1 GB	484.68 GB	24 GB
FP16	1723.2 GB	9.8 GB	1 GB	1734.0 GB	24 GB
