PCXXD友站有文章說,GTX280在Vantage "最高及"測試環境下的分數幾乎是8800U的兩倍....同樣比較的還有ATI下一代4800的分數....只能說下一代卡皇應該確定是NV奪得.....還有GTX260就比9800GX2還猛...真猛..
We chat with a lot of knowledgeable people in the industry and we've learned some quite interesting truth behind GT200 chip. Our developer friends called it brute force chip, with not so much brains.
Putting 240 Shader units in the chip that basically reminds on G80 and G92 design will naturally get things faster. More Shader units at faster clock will always make your card faster, especially at higher resolutions.
G92 with 65nm design has 128 Shaders while GT200 has 240 or almost twice as much. The die size of GT200 is much bigger than G92 and that is how you get the fastest chip around.
Our developer friends added that the last innovation that Nvidia did was G80 and that G92 is simply a die shrink of the same idea. You can look at GT200 as G92 with 240 Shaders.
This results in GT200 running quite hot but it will compensate with sheer power, so let’s just hope that Nvidia's yields of such a huge chip (rumoured bigger than 550mm2) will be acceptable.
也就是說，GT200晶片其實是一顆全靠"蠻力"製造出來的晶片，
為了增加 Shader的數量 到 240 最簡單的方法就是直接把晶片變大，那麼可想而知的，必定不會是很節能的
耗電量想必也是加倍，那散熱怎麼辦？要是風扇差的話肯定噪音也不小囉
