Can RTX 5090 run Nemotron 3.5 Bolt 74B-A9B?

Q: Can RTX 5090 run Nemotron 3.5 Bolt 74B-A9B?

Yes. Measured 154.7 tok/s generation on RTX 5090, via llama.cpp build 11669, NVIDIA mixed 2-bit IQ2 GGUF (22.0 GB). Source: https://llm-speed.com/blog/nemotron-3-5-bolt-74b-24gb-measured At Q4_K_M the weights are about 45.3 GB, more than 32 GB, so Q4_K_M doesn't fully fit without offloading part of the model to system RAM.

Yes. Measured 154.7 tok/s generation (llama.cpp build 11669, NVIDIA mixed 2-bit IQ2 GGUF (22.0 GB); source).

Memory: RTX 5090 has 32 GB. Nemotron 3.5 Bolt 74B-A9B weights are about 45.3 GB at Q4_K_M (74.04B params × 4.89 bits ÷ 8, before context/KV cache). Arithmetic, not a measurement; long contexts need more. Check other quants in the VRAM calculator. At Q4_K_M the weights are about 45.3 GB, more than 32 GB, so Q4_K_M doesn't fully fit without offloading part of the model to system RAM.

Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
