It’s a mad, mad, mad, mad 48V world
The use of 48V is gaining ground in sectors where higher efficiency, power density, and compactness are priorities
Gyoukou Supercomputer Leveraging 48V Factorized Power
Watch the demonstration of Gyoukou, the ExaScaler/PEZY ZettaScaler-2.2 liquid immersion cooling supercomputer with a November 2017 Top500 ranking of #5 reported at 19.1PFlop/s and a Green500 ranking of #4 reported at 14.1GFlops/Watt. Each tank within the system is comprised of 256 processors and utilizes 48V Factorized Power, a high-efficiency, high-density power distribution architecture. PEZY CPUs are co-packaged with Vicor Power-on-Package (PoP) Modular Current Multipliers (“MCMs”) which enable efficient, direct 48V to sub-1V current multiplication at the XPU. The Gyoukou supercomputer is installed at the JAMSTEC Yokohama Research Institute in Japan.
