Build	Quant / setup	Engine	tok/s
DGX Spark (GB10, 128GB): Nemotron 3.5 Super VL 120B and Bolt 74B, launch-week runs	2-bit 24GB GGUF + DFlash speculative decoding (7 draft tokens)	llama.cpp	61.61	source
DGX Spark (GB10, 128GB): Nemotron 3.5 Super VL 120B and Bolt 74B, launch-week runs	2-bit 24GB GGUF, no speculative decoding	llama.cpp	39.47	source

Memory: DGX Spark (GB10) has 128 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.
