The server-specific Blackwell superchip has found its way into a desktop PC, offering unparalleled AI performance with capabilities reaching up to 20 PFLOPS.
ASUS has quietly unveiled the ExpertCenter Pro ET900N E3 Desktop, showcasing the power of the GB300 Superchip paired with 784 GB of coherent memory. This move allows enterprises to harness the impressive capabilities of NVIDIA’s Blackwell superchip in a more familiar desktop form factor. The GB300 combines the high-performance Grace CPU with the B300 GPU, enabling manufacturers to create powerful custom PCs similar to traditional desktops.
For those curious about what a supercomputer with the GB300 superchip looks like, ASUS has answered with the ExpertCenter Pro E900N E3. This machine, hidden within a mid-tower exterior, ranks among the fastest desktops on the market. It’s designed for demanding AI tasks such as Large Language Models, Deep Learning Training, and Scientific Computing.
The system features 784 GB of coherent memory, achieved through a combination of 496 GB of LPDDR5X memory alongside the Grace CPU and 288 GB of HBM3E memory for the Blackwell GPU. This setup delivers up to 20 PFLOPS of AI performance, supported by the ConnectX-8 SuperNIC for 800 GB/s of networking bandwidth, all running on the NVIDIA DGX OS.
In terms of upgradeability, the ExpertCenter offers flexibility with three PCIe x16 slots for additional GPUs and three M.2 slots for fast NVMe SSDs. Unlike standard motherboards, this one includes triple 16-pin power connectors capable of supplying up to 1800W of power. Even with a single GB300 superchip, the potential is significant. NVIDIA also offers the GB300 NVL72 rack for scaling up, featuring 72 Blackwell Ultra GPUs and 36 NVIDIA Grace CPUs, reaching FP4 compute performance up to 1.4 Exaflops and nearly 40 TB of coherent memory.
While this high-performance computing power is primarily aimed at servers, businesses seeking top-tier computing capabilities on their desktops will find the ExpertCenter Pro ET900N G3 more than adequate for intensive tasks. Although ASUS has not disclosed the official pricing, such advanced systems often command a premium.
