Next Generation Power Architecture for Vera Rubin Class AI Servers: The GaN Advantage

9:50 am - 10:15 am

The rapid evolution of artificial intelligence infrastructure is pushing traditional power delivery to its limits. New 800 VDC architectures for Vera Rubin class AI servers, paired with power demands reaching one megawatt per rack, necessitate a shift to advanced semiconductor technologies. GaN devices establish new efficiency benchmarks across the entire 800 VDC power chain, optimizing delivery from the high voltage input directly to the point of load. Outperforming legacy silicon MOSFET configurations, GaN represents the future of high density data center infrastructure. This talk analyzes specific, real world performance breakthroughs enabled by GaN in next generation AI power systems.
