多供養幾家遊戲公司就解決了
就跟優化或是物理加速一樣的策略即可
簡單講就是用錢砸遊戲公司
反正兩家都會這樣
就看誰砸錢的夠多

Crysis效能還是跟5870沒啥差距......
我想是Crysis研發團隊不鳥NV砸錢
或是NV還沒供養到他們才會如此
不過Crysis不是說支持物理加速嗎(幾乎可以認定是有供養到了)
為何還無法像魅影或是阿卡班一樣拉開差距
NV應該檢討是否錢砸的不夠多
讓該團隊心生不滿才會如此吧

有趣的是：就算GTX470的tessellator是5870的14倍(GTX480是16倍)，效能也沒有拉開差距。

我自己的解讀是：顯示卡的3D運算能力已經遇到瓶頸了，再多的tessellator所創造出來的多邊型也沒辦法即時運算完畢。
或是這個軟體的Tessellation還沒多到需要1X個tessellator來處理，所以也沒辦法發揮14個tessellator的效果。

Tessellation是屬於DX11的功能，不是NV獨家，
供養遊戲工作室叫他們大量運用Tessellation頂多只能給ATI壓力，
但無法像Phsyx那樣有完全的排他性
這樣做似乎不頂聰明

要看遊戲tessellation使用量,
但遊戲最後fps所呈現出來的結果,
雖然只是簡單的一個數字,事實上是相當多的因子互相牽引作用的總輸出,
這牽引的因子很多,有時是A因子,有時又變Z因子,
若日後的遊戲tessellation使用量增加,
排除driver影響,應可逐漸拉出一定差距

嗯,只是也要夠快,不要等到拉出距離時6系列,甚至7系列都出來了.

gtx470好像是6+6pin,最大供電225w,
gtx480則是8+6pin,最大供電300w,
當然都是理論值,
gtx470要超到480應該有可能,
但在供電上卻是不及480的

有關噪音的部分
computerbase的描述
http://www.computerbase.de/artikel/...itt_lautstaerke
windows下還算安靜,和系統其它聲音相比,可以忽略,
但一旦執行3d時就很驚人,很大聲,甚至5970都比它安靜,
風扇對loading轉換時很敏感,相當煩人,機殼空氣的流通相當重要

The tested graphics card is installed in a system that is completely passively cooled. That is passive PSU, passive CPU cooler, passive cooling on the motherboard and Solid-State HDD.
This setup allows us to eliminate secondary noise sources and test only the video card. To be more compliant with standards like DIN 45635 (we are not claiming to be fully DIN 45635 certified) the measurement is conducted at 100 cm distance and 160 cm over the floor. The ambient background noise level in the room is well below 20 dbA for all measurements. Please note that the dbA scale is not linear, it is logarithmic. 40 dbA is not twice as loud as 20 dbA. A 3 dbA increase results in double the sound pressure. The human hearing is a bit different and it is generally accepted that a 10 dbA increase doubles the perceived sound level.

On the previous page you read about the power consumption of the GeForce GTX 480. This should give you an expectation what you will see here. Basically all the power consumed by the card ends up as heat and that has to go somewhere.
In idle the fan noise is decent, but certainly not anywhere what we have seen on HD 5870s with custom cooling solutions from AIBs like PowerColor or ASUS . Under load the fan ramps up quickly to make you wish you had earplugs. Same picture here again: similar noise to NVIDIA's last generation cards, while AMD has worked on their noise levels and delivered substantial improvements.

NVIDIA's fan control profile is also set in a way that quickly ramps the fan up and down as load changes, resulting in a more audible experience since your brain tends to notice changing noise levels much more than a constant level.

在idle時還不錯,但無法和5870相比,
load時,風扇轉速快速切換,你會希望有個耳塞,
風扇急起急落,讓人很容易察覺,因人腦會注意噪音變化的改變


噪音感受度和使用環境有關,如果環境是屬於幽靜型的,
在最高負載風扇來到85%(4200rpm),溫度來到91~96度,
如果在夏季炎熱時,大抵只能開冷氣應對吧,
不然就算風扇100%也難保溫度不會破百…

470這樣超，供電不會有問題嗎??

耗能一高,什麼問題都來,
幾年前個人提出一個“忍受值最高理論”,
現在顯示卡(單卡)果然如預料來到近300w,
有人覺得300w不算什麼,如果以後顯卡發展到500w,
能忍受的人又將變少,每個人處在不同忍受階段,但都有其極限,
效能極致追求者也不例外

高溫高耗能的卡,影響的不只本身,系統其他零件都受影響,
溫控的系統風扇、CPU風扇、POWER風扇也連帶飆高,
對於想打造高階低噪音的平台是很大阻礙,
但fermi基本上仍符合”用之則行、舍之則藏”的原則,
一般人在2d使用時間比3d多,
至於遊戲效能,不妨再等幾次的驅動改版看看,
相信NV的DRIVER TEAM現在應該被人拿槍指著幹活吧…
