Asus brings Nvidia’s GB300 Blackwell Ultra “desktop superchip” to workstations — plain-looking desktop more powerful than most server racks, features up to 784GB of coherent memory, 20 PFLOPS AI performance

Asus ET900N G3.

Asus has quietly launched the ExpertCenter Pro ET900N G3, one of the first desktop systems powered by Nvidia’s GB300 Grace Blackwell Ultra “desktop superchip.” This marks a notable shift for Nvidia, which has historically reserved its highest-end AI hardware for its own DGX Station lineup. With Blackwell Ultra, the company is partnering with OEMs like Asus, Lambda, and others to bring AI-focused workstations to a broader market.

The GB300 Desktop Superchip combines a Grace ARM-based CPU with Nvidia’s new Blackwell Ultra GPU—the same pairing that powers the DGX Station announced earlier this year at GTC 2025. This platform delivers up to 784 GB of unified LPDDR5X and HBM3E memory and next-gen Tensor Cores with enhanced FP4 precision, making it ideal for AI training, inference, and large-scale model development. Asus’s ExpertCenter mirrors these design principles with 20 PFLOPS of AI performance, ConnectX-8 SuperNIC networking (800 Gb/s) for high-speed scaling, and support for Nvidia DGX OS.
