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
Vicor and 3M demonstrate the benefits of liquid immersion cooling
Vicor partnered with 3M to demonstrate this advanced data center cooling technique and its benefits. Some of the most advanced processors to date operate in immersion cooling, eliminating the thermal limitations of traditional air-cooled systems. Vicor Power-on-Package for high-performance CPUs/GPUs is immersed in Fluorinert™, the 3M product designed for liquid immersion cooling. The combined solution provides power/thermal performance advantages.
