This is what Nvidia’s Exaflop supercomputer-in-a-rack looks like — the DGX GB200 NVL72 tower most likely uses 48V, 2.5kA to deliver a staggering 1,440 petaflops, could cost millions

Nvidia recently unveiled its DGX GB200 NVL72 supercomputer-in-a-rack at Nvidia GTC 2024 and Patrick Kennedy at Serve The Home took a selection of great photos showcasing the impressive beast.

The name of the DGX GB200 NVL72 tells you much of what you need to know. The GB200 signifies the Grace Blackwell GB200 compute structure, while the NVL72 denotes there are 72 Blackwell GPUs connected by NVLink.

The Blackwell platform contains 208 billion transistors across its two GPU dies. These are connected by 10 TB/second chip-to-chip link into a single, unified GPU. Blackwell, set to ship later this year, will reportedly offer up to 20 petaflops of FP4 power and be up to 30x faster than Hopper for AI inference tasks.
