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
歡迎觀看 ExaScaler/PEZY ZettaScaler-2.2 液浸式冷卻超級計算機 Gyoukou 的演示。據報道,該超級計算機 2017 年 11 月以 19.1PFlop/s 的性能排在 Top500 第五位並以 14.1GFlops/W 的每瓦性能比穩居 Green500 第四。系統內的每個插槽有 256 個處理器,其採用 48V 分比式電源(一種高效率、高密度的配電架構)。PEZY CPU 與 Vicor 合封電源 (PoP) 模組化電流倍增器 (MCM) 合封在一起,其可在 XPU 位置實現直接 48V 至 1V 以下的高效電流倍增。Gyoukou 超級計算機安裝在日本橫濱 JAMSTEC 研究所。
