In brief
- The new 64GB memory version of NVIDIA's DGX Spark launches October 23, 2026 starting at $4,999 through Acer, ASUS, Dell, Gigabyte, HP, and MSI.
- The device, powered by the GB10 Grace Blackwell Superchip, can run models with up to 100 billion parameters locally on its own.
- When two DGX Spark 64GB units are clustered via NVIDIA ConnectX-7, memory scales to 128GB, supporting models with up to 200 billion parameters.
- Blender will be one of the first major creative applications to support the platform, according to NVIDIA, with an installable package coming soon.
NVIDIA has announced a new 64GB unified memory configuration for its desktop AI computer family, the DGX Spark. According to the announcement shared on the company's blog, the new model will go on sale October 23, 2026 starting at $4,999 through manufacturing partners including Acer, ASUS, Dell, Gigabyte, HP, and MSI.
What does the DGX Spark 64GB offer?
The new SKU carries the same GB10 Grace Blackwell Superchip, DGX OS, and NVIDIA AI software stack as the existing 128GB model, with memory capacity being the only difference. According to NVIDIA, the device can run models with up to 100 billion parameters—along with agentic applications built on them—entirely locally on its own. The system ships with NVIDIA ConnectX-7 networking and supports popular runtimes like Ollama, vLLM, LM Studio, and llama.cpp out of the box thanks to its CUDA-accelerated software stack.
What changes when two units are combined?
Two 64GB DGX Spark units can be directly connected via a QSFP cable and clustered using the NVIDIA Sync Cluster Assistant. This brings total memory up to 128GB and supports models with up to 200 billion parameters. According to NVIDIA's own Qwen 3.8 27B benchmark, a clustered two-system setup delivers up to 1.7x the performance of a single system, per the company's claims. With the NVIDIA Sync Model Launcher arriving later this month, users will be able to download models like Qwen3.8 27B with a single click and run them on either a single device or a cluster.
| Configuration | Memory | Supported model size |
|---|---|---|
| Single DGX Spark 64GB | 64GB | ~100 billion parameters |
| Two units clustered | 128GB | ~200 billion parameters |
What does this mean for archviz and architecture offices?
In NVIDIA's announcement, Blender is mentioned as one of the first major creative software providers to support the platform, with a ready-made, downloadable installation package said to be coming soon. In practice, this matters for 3D and archviz studios because AI-powered tools running on local hardware—such as image generation, agentic automation, or document/code analysis—can be tested without cloud costs or data privacy concerns. However, there are important caveats: the device starts at $4,999, representing a significant investment for smaller offices; and for now, only Blender has been named, with no official support announcement yet for other software commonly used in archviz, such as 3ds Max, SketchUp, or render engines. It's also worth noting that the clustering feature only delivers real benefit when two units and a ConnectX-7 connection are used together.
When and where can it be purchased?
The DGX Spark 64GB will go on sale October 23, 2026 through the six manufacturing partners listed above. NVIDIA also announced that RTX Spark-branded Windows computers will arrive during the same period from Acer, ASUS, Dell, HP, Lenovo, Microsoft, and MSI, though pricing and technical details for these models have not yet been shared.

What really matters for the archviz world about the DGX Spark 64GB is less the price tag and more the Blender support. Having locally-run AI models integrated into rendering or scene-preparation workflows could be an attractive option for small and mid-sized studios concerned about cloud costs and data sharing. However, the $4,999 starting price and the need for a second unit for clustering keep this technology, for now, within reach mainly of well-funded offices or research-focused teams.
For archviz studios in Turkey, the practical advice is to hold off on investing in this hardware right away and instead watch how Blender integration performs in real-world use, and whether support extends to more widely used tools like 3ds Max and V-Ray. As the ecosystem expands, the price/performance balance should become clearer.
