Memory: DGX Spark (GB10) has 128 GB. Nemotron 3 Super 120B-A12B weights are about 73.4 GB at Q4_K_M (120B 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.
