Nvidia Unveils 64GB DGX Spark AI Supercomputer Configuration

Nvidia has introduced a new, smaller entry point for its DGX Spark AI supercomputer, unveiling a 64GB configuration on October 2, 2026, with a price tag of approximately $4,999. This launch comes at a crucial time as memory prices are surging and supplies are dwindling, leading to a significant price increase for the original 128GB model, which now retails for $6,950.

The 64GB model is powered by the GB10 Grace Blackwell Superchip, which combines a 20-core Arm CPU and a Blackwell GPU. It maintains a memory bandwidth of 273 GB/s and includes Nvidia's ConnectX-7 networking hardware, allowing users to cluster up to four units together. This configuration is designed for mid-sized model inference, specifically targeting models with approximately 26 to 35 billion parameters.

Notably, Nvidia has partnered with established hardware manufacturers such as Acer, ASUS, Dell, GIGABYTE, HP, and MSI for this launch. The company also plans to release an updated DGX OS software later in October 2026, aimed at simplifying cluster setups and deploying inference models.

The 64GB configuration primarily benefits developers and companies that prefer running local inference on their hardware rather than relying on cloud services. However, potential buyers should consider the trade-off in model size, as larger models may necessitate the more expensive 128GB version or a clustered solution.

As memory prices continue to fluctuate, the pricing of the 64GB configuration may also face pressure, affecting the price gap between the two models.
