[情報] AMD Zen 架構披露!大核心ALU浮點翻倍
硬體愛好者樂園3DCenter最新披露的信息顯示,Zen架構特別關注大幅提升單核心性能,
尤其是每個核心的ALU、浮點單元等都比推土機架構多了一倍。
簡單來說,Zen架構相當於把推土機架構的一個雙核心模塊壓縮成了單個核心,而且還加
入了超線程。
AMD早些年相信,CPU架構可以專注於整數性能,浮點性能則交給GPU,二者相輔相成,結
果誤判了形勢,多線程、通用計算的發展遠未達到預期,我們仍然嚴重依賴於單核性能,
這也是推土機架構紙面上看起來很優秀、實際表現很糟糕的一個重要原因。
Zen顯然改變了態度,有些回歸的意味,再次使用大核心:四個解碼、四個ALU、四個
128-bit寬度浮點單元(組成兩個256-bit FMAC)。這能讓單核心性能大幅度提升,再加上
超線程的加入,每個物理核心的性能比推土機翻一番是有希望的。
