But the machine is far from the fastest GPU in Nvidia's lineup. It's not going to beat out an RTX 5090 in large language model (LLM) inference, fine tuning, or even image generation - never mind gaming. What the DGX Spark, and the slew of GB10-based systems hitting the market tomorrow, can do is run models the 5090 or any other consumer graphics card on the market today simply can't.
Nvidia's tiniest Grace-Blackwell workstation is finally making its way to store shelves this week, the better part of a year after the GPU giant first teased the AI mini PC, then called Project Digits, at CES. Since rebranded as the DGX Spark, the roughly NUC-sized system pairs a Blackwell GPU capable of delivering up to a petaFLOP of sparse FP4 performance with 128 GB of unified system memory and 200 Gbps of high-speed networking.
