AI datacenters are facing a new class of Power Delivery (PD) and Power Integrity (PI) constraints driven by rapid scaling in GPU power and workload dynamics. As GPU power levels approach multiple kW, traditional MBVR based power delivery solutions become highly inefficient. It is estimated that less than half of the power that is fed to the racks will be used for compute. The rest is dissipated in the form of conversion losses, I2R losses and droop induced losses. In this talk we will take a closer look at the key PD/PI challenges in this segment as well as some novel solutions that are being developed to address these challenges.
Kaladhar Radhakrishnan is an Intel Fellow and a Power Delivery Architect with the Technology Development group at Intel. He has played a significant role in shaping and driving power delivery technologies for Intel microprocessors. His areas of expertise are in integrated voltage regulators, advanced packaging and passives technologies. Kaladhar is a two-time recipient of the Intel Achievement Award. He has authored 4 book chapters, over 50 technical papers in peer reviewed journals, and has been awarded 50 US patents. Kaladhar joined Intel in 2000 after he received his Ph.D. in Electrical Engineering from the University of Illinois at Urbana-Champaign, USA.
