小弟猜測可能是功耗搞不定吧，只好忍痛砍掉一些東西
砍掉記憶體頻寬和容量對效能的影響可能比砍掉stream processor來的小些 
編輯：不過這款產品突然讓小弟懷疑，GTX 280和260原本是不是就是同顆晶片然後關閉sp和記憶體頻寬而已啊？
不然Nvidia怎麼有可能突然生出一個生產線專門在生產這顆規格混合的新晶片？ |
記憶體的發熱會很大嗎?
GTX260/280 本來就是同一顆晶片
NV 在設計的時候就考慮到良率問題, 設計上, GT200 共有 11*24 組 管線,
晶片出廠的時候, 先遮避掉一組不良的管線, 這不一定是說完全不能用, 而是可能尚不了高時賣, 這就是 GTX280(240SP)
如果有更多的不良管線組, 就繼續往下割成 GTX 260(192/216)

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
