Can RTX 5070 12GB run GLM-5.2?

NVIDIA · 12 GB GDDR7 · 672 GB/s bandwidth · Z.ai · 753.3B (active 40B) · MoE · model ctx up to 1000K

No — GLM-5.2 at Q4 needs ≈ 419.31 GB even at 4K context, beyond the RTX 5070 12GB's 12 GB GDDR7. It would only run with heavy CPU/disk offload. FP16 needs ≈ 1515.6 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	419.31 GB	No	—
Q4	8K default	423.31 GB	No	—
Q4	32K	447.31 GB	No	—
FP16	4K	1511.6 GB	No	—
FP16	8K default	1515.6 GB	No	—
FP16	32K	1539.6 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).

Q4	414.31 GB	8.0 GB	1 GB	423.31 GB	12 GB
FP16	1506.6 GB	8.0 GB	1 GB	1515.6 GB	12 GB
