Can RTX 4060 Ti 8GB run Phi-4-mini-instruct?

NVIDIA · 8 GB GDDR6 · 288 GB/s bandwidth · Microsoft · 3.8B · model ctx up to 128K

Yes — the RTX 4060 Ti 8GB (8 GB GDDR6) can run Phi-4-mini-instruct. At Q4 with the default 8K context it needs ≈ 3.85 GB VRAM (weights 2.09 GB + KV cache 0.76 GB + 1 GB runtime overhead), which fits within 8 GB. Decode at Q4/8K: ≈ 48.2 tok/s (estimated, batch 1). FP16 needs ≈ 9.36 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	3.47 GB	Yes	48.2 est.
Q4	8K default	3.85 GB	Yes	48.2 est.
Q4	32K	6.13 GB	Yes	48.2 est.
FP16	4K	8.98 GB	No	30.1 est.
FP16	8K default	9.36 GB	No	27.7 est.
FP16	32K	11.64 GB	No	17.9 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).
