Nvidia plans to launch the Rubin Ultra NVL576 rack in the second half of 2027, following next year's Rubin.

The liquid cooled 'Kyber Rack' will consume some 600kW, Nvidia CEO Jensen Huang said at the company's GTC event.

The Vera Arm CPU has 88 custom Arm cores, 176 threads, and 1.8TBps NVLink C2C. The Rubin Ultra includes fore reticle-sized GPUs, with 100 petaflops of FP4, and 1TB of HBM4e.

The Rubin Ultra NVL576 offers 15 exaflops of FP4 inference and five exaflops of FP8 training, with the company claiming a 14x improvement over the GB300 NVL72.

The rack has 4.6PBps of HBM4e, and 365TB of fast memory. It also has 1.5 PBps NVLink7, and 115TBps CX9.

"Each rack is 600kW, 2.5 million parts, and obviously a whole lot of GPUs," CEO Huang said.

"This transition is going to take years of planning, this isn’t like buying a laptop, which is why I am telling you now. We have to plan with the land and the power for data centers with engineering teams two to three years out, which is why I [am showing] the roadmap.”

The following year will see the launch of the Feynman series of GPUs, named after Richard Feynman.
