Can RX 7900 GRE 16GB run DeepSeek-V4-Flash?

AMD · 16 GB GDDR6 · 576 GB/s bandwidth · DeepSeek · 158.1B (active 13B) · MoE · model ctx up to 1000K

No — DeepSeek-V4-Flash at Q4 needs ≈ 89.25 GB even at 4K context, beyond the RX 7900 GRE 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. FP16 needs ≈ 319.8 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	89.25 GB	No	—
Q4	8K default	90.55 GB	No	—
Q4	32K	98.36 GB	No	—
FP16	4K	318.5 GB	No	—
FP16	8K default	319.8 GB	No	—
FP16	32K	327.6 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).
