Sourced rows only. Peak VRAM is recorded by the person who ran the benchmark, so it is a floor for what the card can hold, not a specification. Price snapshots.
Head-to-head
Only one model has been measured on both cards (Qwen3.8-Flash-Next). On that single data point DGX Spark x2 records 93.0 tok/s and Intel Arc Pro B70 x2 records 20.3 tok/s — treat it as one data point, not a ranking.
