On Tuesday, Nvidia announced it will begin taking orders for the DGX Spark, a $4,000 desktop AI computer that wraps one petaflop of computing performance and 128GB of unified memory into a form factor small enough to sit on a desk. Its biggest selling point is likely its large integrated memory that can run larger AI models than consumer GPUs.

Nvidia will begin taking orders for the DGX Spark on Wednesday, October 15, through its website, with systems also available from manufacturing partners and select US retail stores.

The DGX Spark, which Nvidia previewed as “Project DIGITS” in January and formally named in May, represents Nvidia’s attempt to create a new category of desktop computer workstation specifically for AI development.

With the Spark, Nvidia seeks to address a problem facing some AI developers: Many AI tasks exceed the memory and software capabilities of standard PCs and workstations (more on that below), forcing them to shift their work to cloud services or data centers. However, the actual market for a desktop AI workstation remains uncertain, particularly given the upfront cost versus cloud alternatives, which allow developers to pay as they go.

Nvidia’s Spark reportedly includes enough memory to run larger-than-typical AI models for local tasks, with up to 200 billion parameters and fine-tune models containing up to 70 billion parameters without requiring remote infrastructure. Potential uses include running larger open-weights language models and media synthesis models such as AI image generators.

According to Nvidia, users can customize Black Forest Labs’ Flux.1 models for image generation, build vision search and summarization agents using Nvidia’s Cosmos Reason vision language model, or create chatbots using the Qwen3 model optimized for the DGX Spark platform.

Big memory in a tiny box

Nvidia has squeezed a lot into a 2.65-pound box that measures 5.91 x 5.91 x 1.99 inches and uses 240 watts of power. The system runs on Nvidia’s GB10 Grace Blackwell Superchip, includes ConnectX-7 200Gb/s networking, and uses NVLink-C2C technology that provides five times the bandwidth of PCIe Gen 5. It also includes the aforementioned 128GB of unified memory that is shared between system and GPU tasks.

Nvidia announces DGX desktop “personal AI supercomputers”

During Tuesday’s Nvidia GTX keynote, CEO Jensen Huang unveiled two “personal AI supercomputers” called DGX Spark and DGX Station, both powered by the Grace Blackwell platform. In a way, they are a new type of AI PC architecture specifically built for running neural networks, and five major PC manufacturers will build the supercomputers.

These desktop systems, first previewed as “Project DIGITS” in January, aim to bring AI capabilities to developers, researchers, and data scientists who need to prototype, fine-tune, and run large AI models locally. DGX systems can serve as standalone desktop AI labs or “bridge systems” that allow AI developers to move their models from desktops to DGX Cloud or any AI cloud infrastructure with few code changes.

Huang explained the rationale behind these new products in a news release, saying, “AI has transformed every layer of the computing stack. It stands to reason a new class of computers would emerge—designed for AI-native developers and to run AI-native applications.”

The smaller DGX Spark features the GB10 Grace Blackwell Superchip with Blackwell GPU and fifth-generation Tensor Cores, delivering up to 1,000 trillion operations per second for AI.

Meanwhile, the more powerful DGX Station includes the GB300 Grace Blackwell Ultra Desktop Superchip with 784GB of coherent memory and the ConnectX-8 SuperNIC supporting networking speeds up to 800Gb/s.

The DGX architecture serves as a prototype that other manufacturers can produce. Asus, Dell, HP, and Lenovo will develop and sell both DGX systems, with DGX Spark reservations opening today and DGX Station expected later in 2025. Additional manufacturing partners for the DGX Station include BOXX, Lambda, and Supermicro, with systems expected to be available later this year.

Since the systems will be manufactured by different companies, Nvidia did not mention pricing for the units. However, in January, Nvidia mentioned that the base-level configuration for a DGX Spark-like computer would retail for around $3,000.
