Nvidia Grace Blackwell Ultra Superchip systems deploy in production at GPU cloud provider CoreWeave.

Dell has delivered the industry's first systems built on Nvidia's GB300 NVL72 platform to CoreWeave, a leading AI cloud service provider. CoreWeave has deployed the Blackwell Ultra-based cluster with its data center hosting provider Switch. Dell's and CoreWeave's initial rollout involves Dell Integrated Racks equipped with 72 Nvidia Blackwell Ultra GPUs, 36 Arm-based 72-core Grace CPUs, and 36 BlueField DPUs per rack.

Each GB300 NVL72 rack delivers 1.1 ExaFLOPS of dense FP4 inference and 0.36 ExaFLOPS of FP8 training performance, which is 50% higher compared to a GB200 NVL. Each GB300 NVL72 rack features 20 TB of HBM3E and 40 TB of total RAM. The new rack-scale solution relies on Nvidia's Quantum-X800 InfiniBand switches and ConnectX-8 SuperNICs for scale-out connections at up to 14.4 GB/s, twice as fast as previously. These densely configured systems built for maximized training and inference performance are liquid cooled due to their extreme power consumption of up to 1,400W per GPU.

According to Dell, "this delivery of Nvidia GB300-powered solutions is more than a milestone. It reflects the trust our customers and partners continue to place in our expertise. By seamlessly engineering the compute, the network and the storage under one roof and fine-tuning with integration and deployment services, we help our customers move at unprecedented speed and scale." Dell noted that the rack-scale systems come assembled and tested and are designed for fast installation and deployment for production use. This is the second time Dell and CoreWeave have deployed Nvidia's latest AI GPU platform ahead of the industry.

The deployment will enable CoreWeave to enhance its cloud platform to handle more advanced large language model training, reasoning processes, and inferencing. As CoreWeave employs more GB300 NVL72-based racks, total performance available to its customers will increase. Dell and CoreWeave deployed GB300 NVL72 racks approximately seven months after deploying the first GB200 NVL72 machines, suggesting strong demand for Nvidia's higher-performance Blackwell Ultra systems among cloud service providers.
