space No loss in performance
by placing PRM & Digital

board edge areas
space Simplifies CPU
I/O routing
space Lower noise performance
of the VTM removes any
concerns of placement

Higher Efficiency
   
Vicor 48 V Direct to CPU performance matches that of 12 V to 1 V conventional multiphase
The addition of a 48 V to 12 V stage converter to a conventional multiphase only lowers performance further
48 V server racks reduce energy losses by over 30% vs 12 V rack systems
