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.
The practical result, per Nvidia's benchmarks published on its developer blog, is 30x faster real-time inference on trillion-parameter large language models compared with the H100, and 10x faster performance on mixture-of-experts architectures. The rack-scale integration accounts for most of that gain: by collapsing the networking layer inside the chassis, Nvidia eliminates the latency and bandwidth penalty that limits discrete GPU clusters when running the largest models.
StartupHub.ai tracks 414 companies competing in AI chip, GPU, and custom accelerator markets. The density of that field reflects how much capital Nvidia's Blackwell success has drawn into adjacent opportunities, from photonic computing startups to GPU cloud providers. Among those 414, no startup has yet attempted a system-level integration at the scale the NVL72 represents.
Why Huang says the chip is the wrong thing to watch
On Nvidia's Q1 FY2027 earnings call on May 20, 2026, Jensen Huang made an argument that surprised analysts: the chip is no longer the company's most important asset. "Agentic AI has arrived, doing productive work, generating real value and scaling rapidly across companies and industries," Huang said on the call, per CNBC. CFO Colette Kress then quantified the software compound: Blackwell's inference performance improved 1.5x in its first month of deployment through software optimizations alone, building on the 4x inference improvement Hopper achieved over two years through CUDA stack updates.
