Supermicro announces portfolio of Blackwell Ultra systems (HGX B300 NVL16 and GB300 NVL72) for next-generation AI compute.
Supermicro, Inc. (NASDAQ: SMCI) announced new systems and rack solutions powered by NVIDIA's Blackwell Ultra platform at the GTC 2025 Conference, featuring the NVIDIA HGX B300 NVL16 and NVIDIA GB300 NVL72 platforms. Charles Liang, president and CEO of Supermicro, stated: "At Supermicro, we are excited to continue our long-standing partnership with NVIDIA to bring the latest AI technology to market with the NVIDIA Blackwell Ultra Platforms. Our Data Center Building Block Solutions® approach has streamlined the development of new air and liquid-cooled systems, optimized to the thermals and internal topology of the NVIDIA HGX B300 NVL16 and GB300 NVL72." The new solutions are designed to deliver breakthrough performance for the most compute-intensive AI workloads, including AI reasoning, agentic AI, and video inference applications.
Supermicro's advanced liquid-cooling solution delivers exceptional thermal efficiency, operating with 40°C warm water in the company's 8-node rack configuration, or 35°C warm water in double-density 16-node rack configuration. According to Liang, this innovative solution reduces power consumption by up to 40% while conserving water resources, providing both environmental and operational cost benefits for enterprise data centers. The NVIDIA Blackwell Ultra platform delivers an unprecedented 288GB HBM3e of memory per GPU, with networking platform integration including NVIDIA Quantum-X800 InfiniBand and Spectrum-X™ Ethernet doubling the compute fabric bandwidth to up to 800 Gb/s.
The Supermicro NVIDIA HGX B300 NVL16 system is built on a brand new 8U platform with each GPU connected in a 1.8TB/s 16-GPU NVLink domain, providing a massive 2.3TB of HBM3e per system. The system integrates 8 NVIDIA ConnectX®-8 NICs directly into the baseboard to support 800 Gb/s node-to-node speeds via NVIDIA Quantum-X800 InfiniBand or Spectrum-X™ Ethernet. The NVIDIA GB300 NVL72, by contrast, integrates 72 NVIDIA Blackwell Ultra GPUs and 36 NVIDIA Grace® CPUs in a single rack with exascale computing capacity, featuring over 20TB of HBM3e memory interconnected in a 1.8TB/s 72-GPU NVLink domain.
Supermicro's expertise in liquid cooling, data center deployment, and its building block approach positions the company to deliver NVIDIA Blackwell Ultra with industry-leading time-to-deployment. The company offers a complete liquid cooling portfolio, including newly developed direct-to-chip cold plates, a 250kW in-rack CDU, and cooling tower. Supermicro's on-site rack deployment helps enterprises build data centers from the ground up, including planning, design, power-up, validation, testing, installation and configuration of racks, servers, switches and other networking equipment to meet specific organizational needs. GTC 2025 visitors can find Supermicro at booth #1115 in San Jose, California from March 17-21, 2025, where the X14/H14 B200, B300, and GB300 systems will be on display along with rack-scaled liquid-cooled solutions.
