再過兩週 NVIDIA 就要發布 Maxwell 架構的新一代 GTX 980 / 970 顯示卡
但是完整的第二代 Maxwell 架構對我們來說還是個謎
不過有些網站無意中曝光了顯示卡的完整規格
比如 GTX 980 所用的核心擁有 2560 個 CUDA 核心
160 個紋理單元,64 個光柵處理器,雙槽尺寸,6 + 6 pin 供電
比價網站 Geizhals 上已經出現了 GTX 980 4GB 顯示卡
雖然還沒有售價方面的信息
不過他們倒是曝光了 GTX 980 的詳細規格
除了之前的 256bit 頻寬、4GB 記憶體之外
還有 2560 個 CUDA 核心,160 個紋理單元,64 個光柵處理器
(Maxwell 架構中每組 SMM 有 128 個 CUDA 核心,算起來應該是 20 組 SMM)
CUDA 核心以及紋理單元要比現在的 GK110 核心都要少
不過光柵處理器則從目前 32/48 個增加到了 64 個
達到了 AMD R9 290X 顯示卡的水平,有利於提升顯示卡的後端渲染能力
