Memory: DGX Spark (GB10) has 128 GB. Ornith 1.5 122B weights are about 76.5 GB at Q4_K_M (125.1B 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.
