原本以為要等到 9/2 才會聽到新一代 Tiger Lake 行動處理器細節內容,沒想到稍早登場的 2020 年架構日,Intel 已經搶先揭示,採用全新 Willow Cove 架構,比起上一代頻率、頻寬、和 FIVR 效率都有顯著提升。先前我們已經知道這是一顆 10nm 的處理器,現在 Intel 確定將其製程技術命名成 SuperFin。

Intel 表示,10nm SuperFin 是增強型 FinFET 電晶體與 Super MIM 電容結合的全新技術,藉由其優勢來提升應力並減少電阻,已實現更多電源通過通道。

其額外的柵極間距選項,對極致效能的特定晶片,還能提供更高的驅動電流。新型薄阻障層也將通孔電阻降低 30%,進而增強互連效能。

雖然推出時間比競爭對手晚,但 Intel 解釋,SuperFin 內部的重複「超晶格」結構是業界首創技術,領先其他製造商現有的製程能力。

關於全新次世代的 Willow Cove 架構,當然就採用 10nm SuperFin 製程技術,而且是植基於上一代 Sunny Cove 微架構,不僅時脈表現和電力效率都大幅提升,也導入重新設計的快取架構,並藉由 Intel® 控制流強制技術(Intel® Control-flow Enforcement Technology)增強其安全性。

最後是大家很關注的 Tiger Lake,不意外的果然是首款配備新型 Xe 繪圖晶片處理器,以下是幾個比較值得注意的規格:

  • 採用 10nnm SuperFin 製程與 Willow Cove 架構
  • 提高 FIVR 效率
  • 頻寬增加 2 倍。記憶體頻寬約達 86GBs,相容於 LP4x-4267、DDR4-3200;LP5-5400 架構
  • IO-CPU整合 TB4 / USB4、PCIe Gen 4,可替裝置實現低延遲、高頻寬的記憶體存取
  • 多個高解析度螢幕和記憶體之間,提供最高達 64GB/s 的同步頻寬
  • 採用 IPU6 設計,支援多達 6 個 4K30 視訊串流、2 千 7 百萬畫素感光元件;最高提供 4K90 和 4 千 2 百萬畫素影像架構相容能力

The Tiger Lake mobile client architecture, built using Intel 10nm SuperFin technology, achieves a greater than generational performance increase in both its CPU and graphics and adds a number of new features -- all while increasing power efficiency.

Tiger Lake目前已經在生產並出貨,預計年底節慶季節應該就會看到相關 OEM 設備。
