GTX 580在Furmark中是否真的拉不盡所有效能？？

[dean2388]

580有沒有比較低溫了
就找2個對照組比比吧!
GTX480 公板 和 5870公板
在同一個環境下 在 一定時間 下測完 馬上 換卡 換驅動 燒
比比就知了
因為480是在春天出吧
也許現在比一下就知了!
感謝樓主囉!

這種便當盒型的散熱器風扇所能帶出的熱量感覺比較慢
雖然580散熱裝置有新的技術
似乎比以往的280 480效果好很多
不過我想晚一點有改裝散熱器出來的時候
溫度應該可以控制的更低
以前280 480 用改裝散熱器可以跟原廠的最高溫差到20度左右
580我猜可能不會這麼多了
但10度應該還是有的

這兩天在網上有著不同大大所做的GTX 580測試，當中包括小弟
有部份人說使用GTX 580，在Furmark中用不盡GPU 100%效能
這個說法的真假小弟尚未確定，同時我亦很想知道是否這樣
所以我只好在我認識不多的情況下嘗試做一些測試吧

這個已經是確定的事，guru3d 有公開 NV 給的 email，把相關細節說明清楚了
以下這段訊息可以詳讀了解一下

NVIDIA's latest email on the topic:

Earlier this week we briefed you about a new feature we called “Advanced Power Management”. The below information is intended to clarify. First, here are the correct facts about our new technology:

We have implemented new power monitoring and power capping features on GTX 580 boards. Similar to our thermal protection mechanisms that protect the GPU and system from excessive heat generation, the new power monitoring and capping features help protect the graphics card and system from issues caused by excessive power draw.

* Dedicated hardware circuitry on the GTX 580 graphics card performs real-time monitoring of current and voltage on each 12V rail (6-pin, 8-pin, and PCI-Express).
* The graphics driver monitors the power levels and will dynamically adjust performance in certain stress applications such as Furmark and OCCT if power levels exceed the card’s spec.
* Power monitoring adjusts performance only if power specs are exceeded AND if the application is one of the stress apps we have defined in our driver to monitor such as Furmark and OCCT.
* So far we have not seen any real world games that are affected by power monitoring or need power throttling to stay within spec.
* We restrict power monitoring only to stress apps, because we don’t want to limit customers who want to overclock games, and we believe the stress apps are the key apps where the graphics card can benefit from additional protection mechanisms.
* We will enable power monitoring for older Furmark versions in future drivers. The 262.99 driver only identifies Furmark version 1.8. If other thermal stress apps are discovered, they will be added to the protection mechanism from time to time with driver updates.
* We do not provide any end user ability to turn off power capping today.
* The power limits for GTX 580 are set close to PCI Express specs for each 12V rail.
* In this initial implementation, when power capping becomes active, clocks inside the chip are reduced by 50%. Many 3rd party tools have not yet been updated to show this fact, but we suspect updates will be coming to make the internal clock reductions more visible.

要是還不別的測試可行，而小弟能力又可以做到，我絕對願意繼續進行有關測試。

找張GTX480以同樣的設定跑一遍，觀察Furmark顯示的fps數字
一般來說按公版規格頻率都比GTX480還高的GTX580，其fps在相同設定下應該是勝出的
若是fps比GTX480低(或是差異很小)就是被限制功耗(降低頻率)，上述原文也提及目前的第三方工具軟體未能偵測出這些變化
需要等待第三方工具軟體的更新才能使得限制功耗(降低頻率)的情況反應出來

如果FURMARK+GPU OCCT一起燒的話...不知道會有甚麼效果

那就直接用 OCCT V3.1 以上版本測試即可... 他就有 CPU+GPU 一起燒機的功能....
但這樣反到是在燒"電供"喔.... 跟顯卡沒太大關係!

另外 FURMARK 跟 OCCT 一起跑並沒有 1+1=2 的效果... x64 系統小弟不確定
但在 x86 系統下... 硬體會擇一軟體全速執行,另一個就被切到背景慢慢處理... 反之亦然

 

[whitecrow]

國外的測試也有提到這回事

 

[p-sport]

我查了一下我測試480時的fps.

mini fps=39

max=50

Avg平均是55.

看起來fps比580高出許多.

用啥解像，有沒有全選取極端折磨模式？

 

[johnnyliu3377]

請問是否將Furmark執行檔中，主檔名稱改更？
我這樣子對嗎？我將Furmark.exe改成了Test.exe
開了空調，卡裝了進機箱內，室溫約22度

恩...的確是改檔名就好了!;em03;

這樣子nv好像不是用ATi的手法來迴避嚕....;face12;

 

[Toppc]

用啥解像，有沒有全選取極端折磨模式？

簡單啦..
用跟我一樣設定跑看看就知道嚕!

CPU 980X 預設
RAM預設

我這片是EVGA的 核心700 RAM 924

晚點回家再PO上FPS

= =不要叫我跑1600....我LCD只到1280X1024

P.S要點跟我同一版喔 FurMark (Multi-GPU) 1.8.2

 

[p-sport]

我只有裝1.8.0版...

FPS約49~50張平均..稍晚測GTX580比較看看
