的確是,這個是我搞錯了,
4870X2的規格是1G*2,
不過在techreport的測試中有說到
"Cumulatively, 4870 X2's effective memory size is still 1GB, since data must be replicated into each GPU's memory space."
這好像似乎是表示實際上使用只有1G,沒有到2G...
不知道是什麼原因就是了...  |
因為, 每個 GPU都要存一份資料, 所以就算總共有 2G(每個GPU 1G), 實際可用也要減半
下一代多卡技術應該要試著改進這個問題才是, 至少這種單卡多核心的環境下應該要做到

The world has been your battlefield, everywhere you go. The blood of brothers and sons screams out against you. Perhaps you cannot yet hear it, because the soil is not your own, but you will... you will
