ASUS ExpertCenter Pro ET900N G3
The ASUS ExpertCenter Pro ET900N G3 is a deskside AI supercomputing workstation engineered to deliver data centre-class performance within a standalone desktop form factor. Built around the NVIDIA GB300 Grace Blackwell Ultra platform, the system integrates a single NVIDIA Grace CPU Superchip paired directly with a single NVIDIA Blackwell Ultra GPU, forming a tightly coupled compute architecture designed specifically for large-scale AI workloads. This unified design leverages high-bandwidth NVLink-C2C interconnect and up to 775GB of coherent CPU-GPU memory, enabling seamless data access, reduced latency, and efficient processing of massive datasets. Delivering up to 20 PFLOPS of AI performance, the ET900N G3 is optimised for demanding tasks such as large language model training, deep learning, simulation, and advanced analytics, while maintaining enterprise-grade stability, connectivity, and integration within a deskside system.
Grace Blackwell Superchip Architecture
The ASUS system is built around a single NVIDIA Grace CPU Superchip featuring 72 Arm Neoverse V2 cores, paired with a single NVIDIA Blackwell Ultra GPU. This tightly integrated CPU-GPU configuration communicates via NVLink-C2C, enabling high-bandwidth, low-latency data transfer that significantly enhances compute efficiency compared to traditional discrete CPU and GPU setups.
Unified Memory & AI Performance
The ExpertCenter Pro ET900N G3 features a massive unified memory architecture of 748GB, combining CPU and GPU memory into a single coherent pool. This design allows large AI models to be processed without traditional memory bottlenecks, enabling faster training, inference, and simulation workloads while supporting significantly larger datasets than conventional workstation configurations.
AI-Optimised Compute Capability
Delivering up to 20 PFLOPS of AI performance, the ASUS workstation is engineered for intensive AI workloads including LLM fine-tuning, deep learning, and multi-modal model development. The architecture is derived from NVIDIA DGX-class systems, bringing data centre-grade compute capability into a local desktop environment.
Expansion & High-Speed Connectivity
The ET900N G3 includes PCIe expansion capabilities for display output and high-speed networking options such as advanced SmartNIC connectivity, enabling integration into high-performance compute environments. This allows the system to scale across workflows and connect to broader infrastructure where required.
Enterprise Integration & Reliability
