Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
The need for new AI processor power delivery
This video introduces Vicor’s Converter housed in Package (ChiP) Technology.
Vicor Vertical Power Delivery (VPD) is an innovative new approach to powering AI applications that can reduce motherboard copper and processor interconnect resistances by up to 50X. Initially revealed at the AI Hardware Summit in Mountain View, CA this high-performance solution will deliver higher peak and average current delivery (>1000 Amps) than other solutions. Learn more about Vertical Power Delivery in this 10-minute summary presentation by Robert Gendron, VP Product Marketing, Vicor.
