Asus's latest workstation is powered by Nvidia's GB300 Grace Blackwell Ultra "AI superchip."
With the ExpertCenter Pro ET900N G3, Asus aims to offer a "desktop AI supercomputer." The workstation features an Nvidia processor with 72 ARM cores and an Nvidia Grace Blackwell Ultra GPU with a memory bandwidth of 7.1 TB/s.

At first glance, the Asus ExpertCenter Pro ET900N G3 workstation looks like a conventional tower; measuring 23.2 x 58.4 x 56.5 centimeters, the computer is designed to fit on a standard desk. But inside, it houses the latest chips from Nvidia.

That’s because Asus has equipped it with an Nvidia Grace Blackwell Ultra “AI superchip,” which features 72 ARM Neoverse V2 processor cores and a Blackwell Ultra graphics chip. The processor is paired with 496 GB of LPDDR5X RAM with a bandwidth of 396 GB/s, while the graphics chip can access 252 GB of HBM3e VRAM with an impressive bandwidth of 7.1 TB/s. The memory pool, which totals 748 GB, can be combined to process larger AI models.


The built-in power supply delivers 1,600 watts of power. According to Asus, the cooling system can handle the chip’s full power even under sustained load without the need to throttle the processor or GPU. The tower can be expanded via three PCIe 5.0 slots, one of which supports an additional Nvidia graphics card. The tower supports four M.2 SSDs and ships with Ubuntu. The selection of ports is disappointing, as USB 4 or Thunderbolt are nowhere to be found. Instead, there are eight USB 3.2 (10 Gbps) ports, one USB 2.0 port, and two 10 Gbps Ethernet ports.

Pricing and availability

The Asus ExpertCenter Pro ET900N G3 workstation is already listed at several retailers in the U.S. The lowest price from Central Computers is listet at $99,999. More detailed information on the specifications can be found on the Asus website.
