Can RTX 4070 12GB run DeepSeek-V3.2?

NVIDIA · 12 GB GDDR6X · 504 GB/s bandwidth · DeepSeek · 685.4B (active 37B) · MoE · model ctx up to 128K

No — DeepSeek-V3.2 at Q4 needs ≈ 381.67 GB even at 4K context, beyond the RTX 4070 12GB's 12 GB GDDR6X. It would only run with heavy CPU/disk offload. FP16 needs ≈ 1379.2 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	381.67 GB	No	—
Q4	8K default	385.37 GB	No	—
Q4	32K	407.57 GB	No	—
FP16	4K	1375.5 GB	No	—
FP16	8K default	1379.2 GB	No	—
FP16	32K	1401.4 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).

Q4	376.97 GB	7.4 GB	1 GB	385.37 GB	12 GB
FP16	1370.8 GB	7.4 GB	1 GB	1379.2 GB	12 GB
