作者： Jakub Rusinowski · 最后更新： 2026年9月11日
How much GPU VRAM you need to run Nemotron Cascade 2 Nemotron-Cascade 2 30B-A3B by NVIDIA locally, a 31.6B-parameter model. Figures are quantized weights + KV cache + framework overhead, computed from the model's parameter count and published architecture — not a throughput model. See /zh/methodology.
Nemotron-Cascade 2 30B-A3B needs about 20 GB VRAM at Q4_K_M.
VRAM by Quantization
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 10.4 GB | 11.2 GB |
| Q3_K_M | 3.41 | 13.5 GB | 14.3 GB |
| Q4_K_M | 4.83 | 19.1 GB | 19.9 GB |
| Q5_K_M | 5.67 | 22.4 GB | 23.2 GB |
| Q6_K | 6.56 | 25.9 GB | 26.7 GB |
| Q8_0 | 8.50 | 33.6 GB | 34.4 GB |
| F16 | 16.00 | 63.2 GB | 64.0 GB |
