Technological Breakthroughs

NVIDIA GB300 Grace Blackwell Ultra Desktop Superchip

The NVIDIA DGX Station features the NVIDIA Blackwell Ultra GPU connected to a high-performance NVIDIA Grace CPU using the NVIDIA NVLink®-C2C interconnect to deliver best-in-class system communication and performance.

NVIDIA Blackwell Generation Tensor Cores

NVIDIA DGX Station features NVIDIA Blackwell Generation Tensor Cores, enabling 4-bit floating point (NVFP4) AI. FP4 increases the performance and size of next-generation models that memory can support while maintaining high accuracy.

NVIDIA ConnectX-8 SuperNIC

The NVIDIA ConnectX®-8 SuperNIC™ supercharges hyperscale AI computing workloads. With up to 800 gigabits per second (Gb/s), ConnectX-8 SuperNIC delivers extremely fast, efficient network connectivity, and supports linking up to two DGX Stations to scale model capacity and performance even further.

Preconfigured AI Software Stack

DGX Station features an optimised, preconfigured operating system, Ubuntu with NVIDIA AI Developer Tools. This environment comes pre-installed with system-specific configurations and essential CUDA-X™ libraries, providing a seamless, full-stack foundation for accelerating AI development, data science, and local inference workloads.

NVIDIA NVLink-C2C Interconnect

NVIDIA NVLink-C2C extends the industry-leading NVLink technology to a chip-to-chip interconnect between the GPU and CPU, enabling high-bandwidth coherent data transfers between processors and accelerators.

Large Coherent Memory for AI

AI models continue to grow in scale and complexity. Training and running these models within NVIDIA Grace Blackwell Ultra’s large coherent memory allows for massive-scale models to be trained and run efficiently within one memory pool, thanks to the C2C superchip interconnect that bypasses the bottlenecks of traditional CPU and GPU systems.

Workload Optimised Power-Shifting

NVIDIA DGX Stations take advantage of AI-based system optimisations that intelligently shift power based on the currently active workload, continually maximising performance and efficiency.

NVIDIA RTX PRO GPU

NVIDIA DGX Station can be configured with up to one additional NVIDIA RTX PRO™ Blackwell Generation GPU in addition to the GB300 Superchip. This combination gives developers the ability to pair data centre-grade AI compute capability with powerful, ray-traced visualisation and simulation.
