NVIDIA announces 64GB DGX Spark systems for October 23 availability

The short version

NVIDIA announced 64GB DGX Spark systems with the GB10 Grace Blackwell platform, starting at $4,999 and scheduled for October 23 through manufacturing partners. The October 2 announcement is not an immediate shipment notice.

What changed

The smaller-memory configuration retains GB10 and DGX OS; the announcement also describes linking two units and new setup assistance.

What it means for you

Local-AI users can assess the lower starting price against memory needs, but model-capacity and speed figures remain NVIDIA-reported workload claims.

The vendor describes a Sync Cluster Assistant for configuring linked systems. Compare the official setup guidance with the memory and networking requirements of your intended workload before choosing hardware.

Availability is a future plan as of this report. Capacity and speed claims have not been independently reproduced by this catalog. Event precision uses the official October 2 article date.
