好像是單精度、雙精度運算的問題吧?
記得NV 主要是單精度強~ATI是雙精度強~
不過不少人喜歡拿FAH來對大眾洗腦NV卡的通用運算遠勝於ATI~
但對單精度、雙精度 隻字未提~
ATI 5系列卡有針對單精度運算加強~
NV的費米則是針對雙精度運算加強~

是利用率問題
以 RAW power 來看, ATI/AMD 的卡哪一項都打死 NV
但是利用率上, ATI 的程式不好寫, 要同時利用到 1800 個SP 沒那麼簡單
但是要同時利用 512 個就簡單的多

Cain was the first man ever to strike down another... and when the Lord came to him and said ‘What have you done!?’, Cain could not hide his crime. For the voice of his brother’s blood cried out from the very ground
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
