NVIDIA GeForce RTX 2080 Ti 、 RTX 2080 與 RTX 2070 Founder Edition 動眼看,其實是 CG 把風扇質感做糟了

在稍早, NVIDIA 也讓媒體可直接拍攝此次基於 Turing / 圖靈架構的 GeForce RTX 2080 Ti 、 RTX 2080 與 RTX 2070 三張 Founder Edition 公板卡,雖然在昨天的發表會公布 GeForce RTX 20 系列 Founder Edition 所使用的風扇的 CG 圖時,引發不少嘲諷,甚至戲稱此雙風扇設計搭配 CG 繪製的質感,宛如瓦斯爐一樣。

不過在今天看到實際的 Founder Edition 公板卡之後,雖說不像 GTX 10 系列的 Founder Edition 那樣的具獨特設計感,但 GeForce RTX 20 系列的 Founder Edition 風扇遮罩設計其實質感沒有那麼糟;或許是由於 CG 圖的關係,不少人會誤以為 GeForce RTX 20 系列的銀色與黑色部分是亮面,不過實際則是維持金屬噴砂處理的厚金屬遮罩設計,另外側邊的 GeForce RTX 字樣亦會發出綠光。

會做出雙風扇設計而非過往的單鼓風扇設計,最重要的理由就是使散熱效率更好;由於過往公板卡皆是以標準時脈運作,並非鎖定超頻玩家,雖如 GeForce GTX 10 系列的 Founder Edition 的風扇雖然漂亮,但在超頻表現就不及板卡廠單純而暴力的雙風扇或是三風扇設計;而此次 GeForce RTX 20 Founder Edition 在一出廠就已經是比標準時脈更高的情況下,亦是受惠全新的雙風扇設計,同時雙風扇亦較單風扇設計有著相對安靜的優點,另外因應雙風扇並非過往公版的鼓風設計,此次遮罩部份上下亦有簍空協助排熱。

基本上將在 9 月 20 日上市的 GeForce RTX 2080 Ti 與 GeForce RTX 2080 的 Founder Edition 相當類似,有著相同的 266.74 mm 卡長,不過除了刻在正面黑色區域與背板的產品型號差異外,兩款 Founder Edition 在供電的部分也是不同的; TDP 達 260W 的 RTX 2080 TI 具備 8+8 Pin 供電,至於 225W TDP 的 RTX 2080 則採用 8+6 供電。

輸出與介面部份,此兩款旗艦 GPU 均具備 NVLink 高頻寬連接介面,連接埠的位置亦有與散熱器遮罩相同設計風格的防塵蓋,而輸出介面部份目前看起來提供 3 個 DisplayPort 與一個 HDMI ,另還有支援 VirturalLink 的 USB Type-C 介面。

雖然 GeForce RTX 2070 Founder Edition 與 RTX 2080 Ti 、 RTX 2080 的 Founder Edition 有類似的風扇遮罩設計,但若放在旁邊比對,就會發現 RTX 2070 明顯短了一些,根據官方公布的規格,確實卡長縮減到 228.60mm ,同時 8 Pin 供電並非如 RTX 2080 Ti 與 RTX 2080 位於 PCB 側邊而是散熱器遮罩後方,側邊也取消了 NVLink 的連接介面,另在影像輸出介面部份則提供兩個 DisplayPort 、一個 HDMI 、一個基於 USB Type-C 的 Virtural Link 以及一個 DVI 。

取消 NVLink 也意味著 RTX 2070 並不具備雙卡串接的能力,不過以實際層面來說, RTX 2070 雙卡串接也不過是將 CUDA 核心增加到與 RTX 2080 Ti 的數量,雖記憶體達到 8GB + 8GB ,但 RTX 2080 Ti 的 352bit 記憶體頻寬仍更顯優勢,價格上兩張 RTX 2070 也還要加上購買 NVLink 橋接器的價格,還要視遊戲是否支援雙卡模式,同時雙卡運作亦產生更高的功耗,並不會比購買單一張 RTX 2080 Ti 來的划算。
