NVIDIA’s desktop team presents DGX Spark as a true “personal AI supercomputer” form factor: a Grace Blackwell GB10 Superchip system delivering around 1 petaFLOP of FP4 AI performance, 128 GB of coherent unified memory and 4 TB NVMe storage so LLMs and multimodal models up to roughly 200 billion parameters can run locally instead of in the cloud. With the full NVIDIA AI software stack preinstalled and a ConnectX-7 SmartNIC for 100 GbE plus 10 GbE RJ-45, two DGX Spark units can be linked as a mini cluster to push into 400B-parameter experimentation while staying on the developer’s own desktop. https://www.nvidia.com/en-us/products/workstations/dgx-spark/

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

In the interview, NVIDIA positions DGX Spark as a way for researchers and engineers whose laptops are hitting memory and bandwidth limits to keep working inside familiar IDEs and toolchains while offloading training, fine-tuning, RAG and agent workloads to a silent 1.2 kg box beside the monitor. The industrial design deliberately echoes the original DGX-1 Jensen Huang delivered to OpenAI, but compresses a rack-class capability into a footprint of 150 x 150 x 50.5 mm, turning what used to require a lab into something that fits on a shared office desk.
Next to DGX Spark, NVIDIA showcases its RTX Pro 6000 Blackwell workstation GPUs, in Max-Q 300 W, 600 W active-cooled desktop and passive server variants. Built on the Blackwell architecture with 96 GB of GDDR7, a 512-bit memory interface and roughly 1.8 TB/s bandwidth, these boards bring fifth-generation Tensor Cores with FP4/FP8 modes and fourth-generation RT Cores into single-socket workstations, with support for four-GPU configurations over PCIe Gen 5. For CAD, DCC, digital twins, robotics simulation and small-to-mid-scale model training, that combination of VRAM capacity and throughput is what keeps data on-GPU instead of constantly paging to system memory or the network.
Recorded at SC25 in St Louis, the conversation ties these pieces together as a continuum from desktop AI boxes to multi-GPU workstations and datacenter nodes, all sharing the same Blackwell, CUDA and NVIDIA AI Enterprise software ecosystem. OEM partners like Dell, HP, Lenovo, MSI and others are already integrating RTX Pro 6000 Blackwell and Grace Blackwell platforms into their own systems, so developers can choose between a turnkey DGX Spark on the desk, a full workstation packed with RTX Pro 6000 boards under the desk, or scaling out to clusters while keeping a consistent toolchain across the whole AI community.
