來自韓國Businesskorea網站的報導稱,三星、SK Hynix計劃在2016年Q1前為NVIDIA的
Pascal GPU量產第二代HBM顯示記憶體。
在此之前,SK Hynix已經在今年為AMD供應了第一代HBM顯示記憶體,進度領先於三星
而美光選擇了HMC記憶體,技術與IBM的相似,但量產進度上落後於HBM。
HBM 2顯示記憶體在容量及速度上比HBM一代更先進,單個記憶體核心的容量從2Gb提升到
8Gb,速度從1Gbps提升到2Gbps
單個晶片的頻寬從128GB/s提升到256GB/s,不僅支援4- Hi堆棧,還支援8-Hi堆棧。至於
NVIDIA的Pascal GPU,分析了它使用的雖然是HBM 2顯示記憶體
不過依然是4-Hi堆棧,這樣一來其HBM顯示記憶體總容量也就是16GB,頻寬1024GB/s。至
於32GB容量
那需要8-Hi堆棧,技術更複雜,可能還需要一段時間。

該更換配備還是要再等一陣子?
