Can I Run Nemotron Cascade 2 on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM)?

Yes, but it is tight
Yes, but it is tight — Nemotron Cascade 2 30B at Q3_K_M needs about 15.4 GB of the 16 GB usable on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM), leaving only ~0.6 GB before the runtime starts swapping. Expect ~23.3 tok/s (estimated), with room for about 8,192 tokens of context.
Confidence: low · Recommended quantization: Q3_K_M · Estimated speed: ~23.3 tok/s

What to watch out for
- Only ~0.6 GB of headroom at Q3_K_M: a longer context or a second application can push this into swapping.
- Q3_K_M is the only quantization that fits, and it is a heavily degraded one — expect noticeably worse output than the same model at Q4_K_M. A smaller model at Q4 is usually the better trade.
- 2 larger variants of Nemotron Cascade 2 do not fit and would need CPU offload or different hardware.
- This model does not publish its full attention configuration, so the KV-cache share of these figures is inferred from its parameter count rather than computed exactly.
RTX 5060 Ti 16 GB desktop limitations
- The cheapest current 16 GB card, but its 448 GB/s bandwidth caps generation speed well below a 5080 on the same model.
Recommended setup
Ollama or llama.cpp (CUDA/ROCm) — vLLM if you need concurrent serving
How these numbers are calculated
- Memory need = quantized weights + KV cache at 8,192 tokens (f16) + 0.8 GB runtime overhead.
- 16 GB of VRAM on the NVIDIA GeForce RTX 5060 Ti 16GB at 448 GB/s.
- 32 GB of system RAM available for CPU offload when a model exceeds VRAM.
- Throughput is a memory-bandwidth roofline estimate, not a measurement. It is labelled "estimated" everywhere it appears.
- KV cache is inferred from the parameter count because this model does not publish its full attention configuration.
FAQ
Can I run Nemotron Cascade 2 on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM)?
Yes, but it is tight — Nemotron Cascade 2 30B at Q3_K_M needs about 15.4 GB of the 16 GB usable on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM), leaving only ~0.6 GB before the runtime starts swapping. Expect ~23.3 tok/s (estimated), with room for about 8,192 tokens of context.
Which quantization of Nemotron Cascade 2 should I use on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM)?
Q3_K_M — it needs about 15.4 GB of the 16 GB available, downloads as roughly 12.8 GB, and runs at an estimated 23.3 tokens/sec with up to 8K of context.
What limits Nemotron Cascade 2 on RTX 5060 Ti 16 GB Desktop (16 GB VRAM, 32 GB RAM)?
Nothing binding — the model fits with headroom and generates at a usable speed on this hardware.
Which runtime should I use?
