: ---
: The GeForce GTX 970 is equipped with 4GB of dedicated graphics memory.
GeForce GTX 970帶有4GB, 獨占的繪圖記憶體.
: However the 970 has a different configuration of SMs than the 980, and
然而, 970上的SM數量設定跟980不一樣,
: fewer crossbar resources to the memory system. To optimally manage memory
他帶有較少連結記憶體系統的交換器資源.
: traffic in this configuration, we segment graphics memory into a 3.5GB
為了更優化這種狀況中的記憶體存取流量, 我們將繪圖記憶體切成3.5GB
: section and a 0.5GB section. The GPU has higher priority access to the
跟0.5GB的區段. GPU對於3.5GB的區段有存取優先權.
: 3.5GB section. When a game needs less than 3.5GB of video memory per draw
當一個遊戲的繪圖指令只需要用少於3.5GB的繪圖記憶體.
: command then it will only access the first partition, and 3rd party
他就會從第一個區段存取, 然而, 用來量測繪圖記憶體使用量的第三方的
: applications that measure memory usage will report 3.5GB of memory in
應用程式會回報3.5GB的使用量(在970上),
: use on GTX 970, but may report more for GTX 980 if there is more memory
但在980上, 會回報的值可能會超過3.5GB,
: used by other commands. When a game requires more than 3.5GB of memory
如果繪圖指令能用到那麼多. 當一個遊戲需要使用3.5GB的記憶體
: then we use both segments. We understand there have been some questions
那我們兩個區段都會使用. 我們了解大家對GTX970
: about how the GTX 970 will perform when it accesses the 0.5GB memory
在存取0.5GB記憶體區段時的效能有許多疑問.
: segment. The best way to test that is to look at game performance.
最好的量測方式, 是看遊戲的數據
: Compare a GTX 980 to a 970 on a game that uses less than 3.5GB. Then
將980跟970在一個需要使用少於3.5GB的遊戲上來比較.
: turn up the settings so the game needs more than 3.5GB and compare
然後將設定往上調, 直到遊戲使用多餘3.5GB, 然後再
: 980 and 970 performance again.
比較980跟970的效能.

: 官方回應出來了
: 簡單來說就是他們的硬體設計執意如此
: "It's by design, not a bug"
: 雖然他們自己說實際上在存取最後0.5GB的效能遞減並不嚴重
: 但是實際上真的會把4GB都塞到炸掉的人應該也大都不是普通人了...
