Nvidia unveiled Grace Blackwell chip architecture at Computex 2025, a new generation optimized for machine learning and high-performance computing.

At Computex 2025, Nvidia bypassed the main exhibition floor and hosted its own "GTC Taipei" event at a nearby hotel, where CEO Jensen Huang delivered keynote speeches unveiling new AI-focused hardware. The two primary announcements were the DGX Spark, a compact mini PC aimed at AI developers, and the DGX Station, a more powerful workstation-class system. To support these initiatives, Nvidia assembled a range of OEM partners with 11 models expected across the Spark and Station lines.

The DGX Spark is built around the new Nvidia GB10 Grace Blackwell Superchip, which combines a 20-core Arm CPU co-developed with MediaTek—featuring 10 Cortex-X295 and 10 Cortex-X725 cores—and a GPU based on Nvidia's Blackwell architecture. Designed for developers, the device delivers up to 1,000 TOPS (FP4/sparse) of performance and ships with a Linux-based DGX OS, Nvidia's AI development suite also used in its data center platforms like Blackwell and Hopper. Several partners, including Acer, Asus, Dell, Gigabyte, HP, Lenovo, and MSI, had models on display, though only visible differences in external design were apparent to attendees, and no internal teardowns were permitted during the event.

The DGX Station, aimed more directly at professionals needing high-end workstation PCs, features the GB300 Grace Blackwell Ultra Desktop Superchip and comes equipped with 288GB of HBM3e memory on the GPU alongside a 72-core Neoverse V2 CPU paired with 496GB of LPDDR5X RAM. Like the Spark, it runs on DGX OS and supports Nvidia's full AI development stack. The DGX Station board shown at the exhibition was a mockup, though the actual product was displayed during a separate session, with full availability not expected until late 2025.

The DGX Station will only be available through OEMs, with Asus, Gigabyte, MSI, and Supermicro leading the rollout. This fragmented distribution model could introduce variation in build quality and thermal performance, critical factors for users seeking the best workstation PC. Questions remain about how finalized both systems are, and potential buyers may want to wait for detailed reviews before making a purchase.
