NVIDIA DGX Spark vs NVIDIA Tesla P100 16GB for local LLMs
57 reports on the NVIDIA DGX Spark and 8 on the NVIDIA Tesla P100 16GB
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 2.7x higher on the NVIDIA Tesla P100 16GB (273 GB/s on the NVIDIA DGX Spark, 732 on the NVIDIA Tesla P100 16GB).
