NVIDIA DGX Spark vs M2 Max 32GB for local LLMs

57 reports on the NVIDIA DGX Spark and 2 on the M2 Max 32GB

Which is faster for local LLMs?

On Qwen3.6 35B · 3B active at 4-bit, the NVIDIA DGX Spark runs at 78.3 tokens per second (one run) and the M2 Max 32GB at 39.3 (2 runs). Those are community reports whose engines and settings differ, so the gap is a rough sign, not a controlled measure of the two cards. Memory bandwidth, which caps how fast a card can write, is 1.5x higher on the M2 Max 32GB (273 GB/s on the NVIDIA DGX Spark, 410 on the M2 Max 32GB).

Estimated by the calculator

The quant the calculator recommends for each card and its estimated speed at a 32,768-token context with 32 GB of system RAM, from memory bandwidth and the model's shape. Where a model was also measured above, the measurement wins.
