Nvidia's next-generation Vera Rubin GPU racks will run at roughly 250 kW per rack, with the subsequent Vera Rubin Ultra generation reaching about 600 kW per rack, en route to eventual one-megawatt AI data center racks.
“The current generation of blackwell chips uh is 130 kW in the rack. Uh the next generation Vera Rubin is going to be 250. Um and then Ver Rubin Ultra is expected to be 600. We're ultimately going to get to one megawatt racks.” View on YouTube
The cited Vera Rubin (~250kW) and Vera Rubin Ultra (~600kW) rack power figures match Nvidia's published product roadmap.
