0 reports on the A18 Pro 8GB and 57 on the NVIDIA DGX Spark

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 4.5x higher on the NVIDIA DGX Spark (60 GB/s on the A18 Pro 8GB, 273 on the NVIDIA DGX Spark). The estimates below compare them on the models people run most.
