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
ExaScaler/PEZY ZettaScaler-1.8 超級電腦能夠以 1.5 PetaFLOPS/m 的性能密度刷新計算性能的極限。ZettaScaler 由 Vicor 模組提供支持,可充分發揮 HV 配電以及 48V 直接至 CPU 架構的優勢。能爲這樣的高性能超級電腦提供部件並與 ExaScaler/PEZY 這樣的創新公司合作,Vicor 深感自豪。
Vicor 電源模組能夠通過幾款高度集成的電源模組實現從 380V 至 CPU 的高效率和高密度。Vicor BCM 模組可在其 24 個磚型 CPU 集羣中的每個集羣中將 380V 轉換爲 48V。在每個 PEZY 磚型 CPU 集羣中,48V 可配送給 32 塊 PEZY-SCnp48 模組卡。每塊 PEZY 模組卡使用一款 PRM 和兩款 VTM 提供 48V 直接至 CPU 的電源。
