In a significant advancement for artificial intelligence infrastructure, CoreWeave has integrated the latest Nvidia Blackwell Ultra supercomputing systems into its cloud AI services. These powerful new machines leverage the cutting-edge GB300 NVL72 platform, marking a pivotal moment in high-performance computing for AI applications. This strategic enhancement is set to deliver substantial gains in processing capability for various AI workloads.

The recent deployment is a joint effort between CoreWeave and Dell, with Dell providing fully integrated racks of these advanced systems. Each rack is a formidable powerhouse, housing 72 Blackwell Ultra cards, which collectively feature 36 Arm-based 72-core Grace CPUs and 36 BlueField DPUs. A key highlight of this integration is the sophisticated liquid cooling system required to manage the immense heat generated, with each GPU consuming up to 1,400W. Dell’s role included pre-building and rigorous testing of these units before delivery, ensuring a streamlined deployment process for CoreWeave. This new infrastructure boasts impressive performance metrics, offering 1.1 ExaFLOPS of dense FP4 inference and 0.36 ExaFLOPS of FP8 training performance per rack, and is expected to double the speed for scale-out connections, reaching up to 14.4 GB/s. This allows for faster and more efficient training of large language models and a boost in AI reasoning abilities.

This rapid integration of the Blackwell Ultra line, merely seven months after the initial GB200 deployment, highlights the accelerated pace of innovation in the AI hardware sector. While CoreWeave benefits from leading-edge performance today, this quick succession of upgrades raises questions about the long-term investment cycles and the sustainability of such rapid advancements in high-performance AI infrastructure. The continuous pursuit of greater computational power drives progress, pushing the boundaries of what artificial intelligence can achieve, enabling new discoveries and applications across various domains.
