It keeps the GB10 Grace Blackwell Superchip, DGX OS and NVIDIA’s AI software stack, but has half the unified memory of the original 128GB configuration.
What is the NVIDIA DGX Spark 64GB?
It is a new memory configuration of NVIDIA’s compact local AI computer, rather than a different platform. NVIDIA says it retains the GB10 Grace Blackwell Superchip, DGX OS and the full NVIDIA AI software stack used by the 128GB model. The announcement does not provide a complete specification sheet for every partner’s 64GB system.
The main stated change is unified memory: 64GB instead of 128GB. That capacity can affect which models and workloads fit on a system, but memory alone does not determine speed, context length or practical suitability.
How does the 64GB model compare with the 128GB DGX Spark?
| Configuration | Unified memory | NVIDIA’s model-capacity statements | Price and timing |
|---|---|---|---|
| DGX Spark 64GB | 64GB, according to NVIDIA’s October 2, 2026 announcement. | NVIDIA says it supports models up to 100 billion parameters on-device. This is a vendor capacity claim, not an independent performance test. | Announced starting price of $4,999; partner availability announced for October 23, 2026. |
| Original DGX Spark 128GB | 128GB, according to NVIDIA’s October 13, 2025 launch announcement. | NVIDIA said it supports inference on models up to 200 billion parameters and local fine-tuning of models up to 70 billion parameters. These are separate claims from the original launch announcement, not directly comparable benchmark measurements. | Not stated in the cited original launch announcement. |
The specifications and claims in this table come from NVIDIA’s October 2, 2026 announcement and its October 13, 2025 launch announcement. A parameter count does not by itself establish whether a particular model will fit with the desired settings or run at a useful speed.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
How much will it cost, and when will it be available?
NVIDIA announced a $4,999 starting price for the 64GB DGX Spark and said it would be available from Acer, ASUS, Dell, Gigabyte, HP and MSI starting Friday, October 23, 2026. These are announcement details, not confirmation of stock: NVIDIA has not established partner-by-partner pricing, regional inventory or verified retail listings in the cited material. Check the relevant manufacturer’s current listing for the price and availability in your region.
Can two 64GB systems combine their memory?
NVIDIA says two 64GB DGX Spark systems can connect using NVIDIA Sync Cluster Assistant and pool memory to 128GB. The company also reports up to 1.7× performance versus one system in its test with Qwen 3.8 27B. That is NVIDIA’s result for the named test; the announcement does not provide enough methodology to apply the figure to other models or workloads.

What the announcement does not establish
NVIDIA’s statements describe intended capacity and a specific vendor test, not independent results for a buyer’s workload. The cited materials do not establish independent performance benchmarks, noise or power measurements for the 64GB model, full specifications for each partner SKU, or current stock. The DGX Spark product page and DGX Spark hardware guide provide platform context, but do not independently verify detailed specifications for this new configuration.
