NVIDIA DGX Spark vs M5 32GB for local LLMs

91 reports on the NVIDIA DGX Spark and 4 on the M5 32GB

Which is faster for local LLMs?

Nobody has reported the same model at the same quant on both cards yet, so there's no measured head-to-head. Memory bandwidth, which caps how fast a card can write, is 1.8x higher on the NVIDIA DGX Spark (273 GB/s on the NVIDIA DGX Spark, 154 on the M5 32GB). The estimates below compare them on the models people run most.
