一切都要看最終規格...

以下是不負責任推算... 錯了請指正

記的之前有人得出 5870 跟 gtx295 略有勝負的結論

假設, 其他都一樣, 單就 SP 效能來看:

1242*480 * X = 1600*850
(x= 效能調整常數)
x=2.218126677402

再假設基本架構不變, 也就是上面的常數不變的情況下

GTX480 的 SP 時脈至少要 1242以上 才能跟5870 打平

要贏30%, 時脈至少要1614 MHz...
我覺得很拼... orz, 以第一版Fermi 良率問題來考慮... 能有 1450 MHz 上下我就覺得很了不起了

在1400 MHz 的時脈下... 推算平均大約贏個 12%,
考慮其他因素, 像是延遲之類, 我個人估計 10 % 上下, 高解析度下可能會拉開

GTX470 能不能以拉高時脈壓過 5850, 就不得而知

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
