Can MI300X 192GB run GLM-4.5?

AMD · 192 GB HBM3 · 5300 GB/s bandwidth · Z.ai · 358.3B (active 32B) · MoE · model ctx up to 128K

No — GLM-4.5 at Q4 needs ≈ 201.27 GB even at 4K context, beyond the MI300X 192GB's 192 GB HBM3. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 265.5 tok/s (estimated, batch 1). FP16 needs ≈ 724.0 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	201.27 GB	No	274.0 est.
Q4	8K default	204.47 GB	No	265.5 est.
Q4	32K	223.67 GB	No	221.9 est.
FP16	4K	720.8 GB	No	5.9 est.
FP16	8K default	724.0 GB	No	5.8 est.
FP16	32K	743.2 GB	No	5.5 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).
