Can RTX 4090 run Nemotron 3.5 Bolt 74B-A9B?
Probably only partly: the weights are larger than its memory, so part of the model likely ran from system RAM. Measured 108 tok/s generation with part of the model offloaded to system RAM (llama.cpp, llama-bench tg128 (quant per result); source).

Memory: RTX 4090 has 24 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.
Speeds are decode (generation) tokens/sec as reported by each source; quant, engine and context differ, so small gaps are noise.
