NVIDIA去年推出了12nm製程的Turing GPU核心,同時還用上了GDDR6
這一次是NVIDIA首發了代表新一代技術的GDDR6,AMD在過去兩年中一直希望高階顯示卡能
普及HBM2。
AMD在今年的7nm Navi顯示卡RX 5700系列上也使用了GDDR6,時間上要比NVIDIA晚了將近
10個月
不免讓人以為AMD在GDDR6技術上落後了。不過AMD高階主管Scott Herkelman此前在接受採
訪時否認了這個說法
他指出AMD研發GDDR6技術已經三年了,在研發RDNA架構時就決定上GDDR6了。
AMD在主流顯示卡上使用GDDR6也意味著HBM2顯存要告一段落了,不過Scott Herkelman表
示HBM2不會徹底消失
其高頻寬優勢決定了它在部分場合依然有用武之地。從這個表態來看AMD會把HBM存用在高
階顯示卡及計算卡上
比如Radeon VII這樣的顯示卡,後者就配備了16GB HBM2,頻寬1TB/s,除了玩遊戲還可以
勝任3D渲染之類的工作。
