NVIDIA DGX Spark vs NVIDIA RTX 3060 12GB for local LLMs
72 reports on the NVIDIA DGX Spark and 50 on the NVIDIA RTX 3060 12GB
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 32% higher on the NVIDIA RTX 3060 12GB (273 GB/s on the NVIDIA DGX Spark, 360 on the NVIDIA RTX 3060 12GB).
