確實某些軟體功耗使用偷吃步,不過散熱器的改進應該是有的,
以techpowerup來看,furmark省了一半的耗能,
原來是153w,解放後304w,只比gtx480稍省電



computerbase是用crysis warhead 1920x1200去量測,

也就是高階卡最可能的使用情境,
耗能比5970稍高,比gtx480稍低,
這和tpu的平均3d耗能差不多

看起來效能有威到，原本roadmap去年就要上場的Fermi完整版終於現身了 :agree:
效能能跟HD5970一搏，發熱又比GTX480大幅減少
不知道AMD的6970能不能來場重量級對決，有看到網路謠言69系列遇到良率問題
耶誕大餐不知道能不能生得出來，希望是煙霧彈 :agree:

不過我不是玩家，比較期望AMD能生一個免外接電源的HD67xx，撿這種就很滿意了 :agree:


煙霧彈？受台積電產能拖累，HD 6900系列可能延期
http://www.expreview.com/12633.html

AMD計劃在本月22日推出使用Cayman GPU的Radeon HD 6900系列顯卡，打算用新的高端顯卡
在聖誕購物熱潮中吸引消費者來購買，但是這一計劃可能因為台積電產能問題而泡湯了。

之前消息提到，Cayman XT擁有1536個流處理器，96個紋理單元，32個ROP，顯存控制器位
寬為256bit，這樣的核心所擁有的晶體管數量和核心面積肯定不會太少，Cayman估計碰到
了和GF 100類似的問題導致量產品良品率不高。

據線人消息，Cayman的良品率依然在個位數徘徊，這樣的產能直接打亂了AMD今年第四季度
在顯卡市場上產品佈局，HD 6900系列很可能會因此延期發佈。

According to our sources, yields for Cayman are still in the single digits
and there's minimal chance AMD will have any shot of achieving its schedule
or production/ship targets for Q4.

如果HD 6900不能如期出現在市場上面的話，高端顯卡市場將會被NVIDIA GeForce GTX 580
搶去不少份額，不知道AMD能不能搶在聖誕節之前發佈新的產品呢？

記得之前版上好像有大大出來澄清只是謠言? :confused:

AMD’s Cayman Christmas card delayed say Taiwanese sources

http://www.techeye.net/chips/amds-c...iwanese-sources

Fabless chip shop AMD was set to launch its "Cayman" GPU (aka AMD Radeon HD 6970) in the week of November 22nd - just in time for the tech-Xmas season – but reliable word from the Taiwanese street is that the product has been delayed due to yield problems at apparently not-so-fab Fab TSMC.

The high-end HD 6970 Cayman GPU-based board is reported to have a whopping 2GB of GDDR5 memory and a 256-bit controller which – at least in terms of RAM quantity- is more powerful than Nvidia’s upcoming GeForce GTX 580 card which only sports a sniff-worthy 1.5GB.

Of course, as most people with common sense know, 1GB is more than enough for even the most high end cards, but GPUs are an ego based game and bigger is always better – at least according to the mad men of tech marketing.

It doesn’t matter how big you are, however, if you don’t show up and put some skin in the game which, according to our talkative Taiwanese buddies is likely the case for AMD which simply cannot yield the product in any significant volume at manufacturer TSMC on time.

According to our sources, yields for Cayman are still in the single digits and there's minimal chance AMD will have any shot of achieving its schedule or production/ship targets for Q4. This could also really hurt if Nvidia successfully launches its GTX 580 in volume – despite its smaller RAM offering.

No doubt this will all come to light when samples slated for press testing get held up in the holiday post. We’ll bring you more as we hear it.

[rumor] 大意是說之前nVidia Fermi在台積電波折的製程良率問題，現在AMD新一代高階GPU-Cayman 恐怕也遇到了。

No 是 15％沒錯啊

增量要用（100-87）/87 ＝15％
或100/87-1 ＝15％

從Anandtech測試與網友發言，有人說這是張485....其實跟大部分網友所料也不遠

好像是把早產fermi塞回母體，再延遲七月月後終於生出正常的fermi，在耗電與效能比上追趕上58xx

有沒有新的architecture? 好像只是修補了"漏電"(早產兒需要更多營養?)和多了"FurMark"降頻 ( :jolin: )

其他的效能都是從更高的頻率...等等補回



不過正常的fermi一出生，對比才出生半年多的早產fermi 480，至少是值得網友掏出腰包的
(間接宣判了480死刑)

但若對比AMD的6xxx，個人覺得，仍然輸了一步
(看看6850和6870的cf，69xx效能/耗電幾可預測...就不知價格如何而已)

還是沒有BITSTREAM DOLBY TRUEHD/DTS MASTER HD輸出...
這是GF100的宿命嗎? :cry: :stupefy:

NV現在進步很多了

這次從聽到GTX580的消息,到正式鋪貨

兩者的時間差縮短很多了

以前的NV常常打高空說要要推出啥驚人之作,結果卻讓消費者經歷漫長的等待期 :flash:

如果是因為東西可能早就設計好了只是卡在製程良率呢?? :jolin:

你是覺得AMD哪一片會降價啊,
市場定位不同吧,
NV要趕快出中階卡,68XX才會有降價的希望.
