Can RX 7800 XT 16GB run MiMo-V2.5?

AMD · 16 GB GDDR6 · 624 GB/s bandwidth · Xiaomi · 310.0B (active 15.0B) · MoE · model ctx up to 1024K

No — MiMo-V2.5 at Q4 needs ≈ 173.0 GB even at 4K context, beyond the RX 7800 XT 16GB's 16 GB GDDR6. It would only run with heavy CPU/disk offload. FP16 needs ≈ 624.0 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	173.0 GB	No	—
Q4	8K default	174.5 GB	No	—
Q4	32K	183.5 GB	No	—
FP16	4K	622.5 GB	No	—
FP16	8K default	624.0 GB	No	—
FP16	32K	633.0 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).
