Nvidia's GB200 NVL72 rack-scale system treats 72 interconnected GPUs as a single processor and streams data at 130 terabytes per second, a design that helped push data center revenue to $75 billion in the three months ending April 2026, up 92 percent year over year, according to CNBC's reporting on Nvidia's Q1 FY2027 results.
A rack that processes as one
The GB200 NVL72 is not a GPU in the traditional sense. It is a rack-scale system: 72 Blackwell B200 GPUs and 36 Grace CPUs assembled in a liquid-cooled cabinet and connected by Nvidia's fifth-generation NVLink at 1.8 terabytes per second of bidirectional bandwidth per GPU. The 72 GPUs share a unified 130 TB/s data fabric, courtesy of an integrated NVLink Switch spine that connects all 72 chips across 5,000-plus high-performance copper cables, allowing the entire rack to act as a single massive accelerator rather than a cluster of discrete chips requiring external networking. Each B200 GPU carries 192 gigabytes of HBM3e memory at 8 TB/s of memory bandwidth, more than double the H100 generation, per Nvidia's product specifications.
