NVIDIA GTX 1080/1070已經出世,AMD的新核心還在不斷曝光。
今天,TechPowerUp又收到了AMD下一代北極星家族首發兩款核心Polaris 10/11的
一些情報,看起來還是挺振奮的。
首先是性能級的Polaris 10(Ellesmere),最新說法稱它只有32個計算單元,
達不到預計中的40個。如果每個單元還是64個流處理器,那就是總共2048個。
確實不多,但是單精度浮點性能可達5.5TFlops,而現在2816個流處理器的R9
390X/FirePro W9100也不過5.2TFlops。
單以此指標計算,可以知道新核心的效率提升了足足45%!
更可喜的是,架構的改進加上16nm工藝的引入,Plaris 10核心顯卡的熱設計功耗會低於
150W,也就是只需一個8針供電接口就行了,一如GTX 1080/1070。 ——R9 390X可是高達
275W呢。
新卡支持256-bit GDDR5/5X顯存,不過首發只會有GDDR5,等效頻率7GHz,容量最大8GB。
技術方面,Ploaris 10會支持H.265視頻格式硬件解碼編碼,並支持DisplayPort 1.3、
HDMI 2.0a輸出。
再看主流級的Polaris 11(Baffin),只有14個計算單元,也就是896個流處理器,因此將
會取代現在的R9 370/360系列。
它的單精度浮點性能可達2.5TFlops,搭配128-bit GDDR5顯存,容量最大4GB,而功耗不
超過50W,無需輔助供電。
