Can Gaudi 3 128GB run gpt-oss-120b?

Intel · 128 GB HBM2e · 3276 GB/s bandwidth · OpenAI · 120.4B (active 5.1B) · MoE · model ctx up to 128K

Yes — the Gaudi 3 128GB (128 GB HBM2e) can run gpt-oss-120b. At Q4 with the default 8K context it needs ≈ 68.24 GB VRAM (weights 66.22 GB + KV cache 1.02 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 408.8 tok/s (estimated, batch 1). FP16 needs ≈ 242.82 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	67.73 GB	Yes	408.8 est.
Q4	8K default	68.24 GB	Yes	408.8 est.
Q4	32K	71.3 GB	Yes	408.8 est.
FP16	4K	242.31 GB	No	89.6 est.
FP16	8K default	242.82 GB	No	89.2 est.
FP16	32K	245.88 GB	No	87.0 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).
