我是沒有去看一些7970與6970的比較
不過從鐵匠大的VGAMaster1203數據來看
7970效能比起6970提升了52%
對於AMD自己算是及格了

個人認知中
AMD跟台積電的合作似乎比NV更能配合
也可以說是AMD比較能掌握台積電的能耐
這方面的優勢大概來自於AMD自己有過晶圓廠
除了自己以前的晶圓廠還有長年配合的晶圓代工廠
比起NV更知道晶圓製造的專業知識 也更熟悉晶圓製造
AMD沒有設計出更大的旗艦級顯示晶片
就是因為他們比起NV更知道台積電的配合能力
一方面也是自己一貫的產品策略吧
NV跟台積電應該也在GK110上花上不少心力後
才認知以現在的28nm不足以讓它具有商業化的價值

以上是個人以一些聽到、看到的消息來猜想

低一階的晶片的確比較適合合體...

而且頻率只差一點點又沒有閹割。

BUILT-IN FXAA AND NEXT-GEN NVIDIA CARDS SOON

Posted Today, 10:57 AM
The anticipation and hype has been building. NVidia will soon release their next-generation video card code-named Kepler and most likely built-in FXAA will also be released at the same time with it. Recently at the Game Developers Conference they showed off the Samaritan game demo using a model of the Kepler card. They were touting the fact that when they demo'd the game one year ago it took three GTX 580's to run the demo but this time it only takes one Kepler card. But wait a minute. Haven't you heard about optimizing a game engine? Epic, the game developer, has had one whole year to optimize the game engine and that can make a huge difference in game performance.

Then there's the FXAA (Fast Approximate Anti-Aliasing) built into drivers. It is a post-processing Anti-aliasing technique and much faster than MSAA (Multisample Anti-Aliasing) commonly found in most games. It is of higher-than-usual benefit to the game Samaritan because Samaritan uses a lot more deferred shading than a game usually does. We have recently seen some Heaven benchmarks involving the NVidia 295.18 driver which has the FXAA feature. Tested on Win 7 64-bit with a GTX 580, 4x Anisotropic, Ambient Occlusion off, 1920 x 1080 resolution.

Scores - Min FPS - Avg FPS - Max FPS
2331 ----- 46.7 ----- 92.6 ----- 192.2 ---> DX 9, driver 296.10, 4x MSAA
2333 ----- 47.8 ----- 92.6 ----- 192.1 ---> DX 9, driver 295.18, 4x MSAA
2625 ----- 50.3 ---- 104.2 ----- 204.7 ---> DX 9, driver 295.18, FXAA ON
1824 ----- 35.1 ----- 72.4 ----- 169.1 ---> DX 11, Norm Tess, driver 296.10, 4x MSAA
1817 ----- 34.7 ----- 72.1 ----- 169.7 ---> DX 11, Norm Tess, driver 295.18, 4x MSAA
2053 ----- 46.3 ----- 81.5 ----- 181.6 ---> DX 11, Norm Tess, driver 295.18, FXAA ON

In DirectX 9 tests the Average FPS is improved by 12.6% when using FXAA rather than 4x MSAA.
In DirectX 11 with Normal Tessellation tests the Avg FPS is improved by 13.5% and the Min FPS is improved by a tremendous 33.4%. That's big.

So yeah, I think we're going to see the FXAA come with the release of the drivers that come with the release of the Kepler cards. I've seen some mention that the NDA on discussing the card and the driver is off on Thu March 22 and I've seen some mention that NVidia is holding a press conference on Wed Mar 28. There's a little bit of hype in it all but without question we're going to want the end result whatever it is.

基本上快點把東西放出來比較重要... :stupefy:

這家媒體是不是搞錯NDA時間阿...竟然已經放出那麼多GTX680的資訊...
我只放上效能實測的部分，前幾頁有其他特點介紹。
如果這篇是真的，那A社真的要準備大降價了呢 :like:

一推人 通通都不知道在亂猜

明明就是

GK978 :flash:

拭目以待...反正我又要半夜守候了...
附帶一提NEWEGG挺有良心的，我上次退掉7950時不小心多按了一次UPS標籤，昨天NEWEGG主動把多一次的運費退回了.

GTX 680 will be hard to get

GTX 680 will be hard to get
Written by Fuad Abazovic
Expect it to sell out like the new iPad

Many of our industry sources are telling us that Kepler based GTX 680 desktop cards will be hard to get.

Despite quite high prices, these cards will sell out very quickly simply as they will be a better choice than similarly priced AMD cards. However, at the same time, AMD can mess up Nvidia’s launch by dropping prices and making its cards more attractive, but this is something that might happen close to GTX 600 series Kepler 28nm launch.

Partners would not be partners if they would not complain about the quantity of Kepler cards that they will get at launch and weeks to come. They all think they deserve and should get more, but they are still convinced that the new cards will sell well.

If you are after GTX 680, our advice is to look for one at launch day, scheduled for March 23 and immediately buy one. Otherwise you will probably end up waiting. The 28nm process is not at great yield levels but it is still reportedly better than the transition to 40nm a few years ago. Nvidia is also having to use a lot of capacity to service OEM deals in both notebook and desktop segment. That will swallow many of the 28nm Kepler based cards.

Nvidia lovers have not much to worry about this as notebooks get lower TDP chips, but since the 680 is close to 200W TDP this remains desktop-only card that will only end up in some high-end desktop machines.

Nvidia GTX 680 brings multi-display support

Nvidia GTX 680 brings multi-display support
Written by Slobodan Simic

Up to four displays on single card

While chasing specifications and performance numbers of the upcoming GK104 Kepler based Nvidia GTX 680 card, we kinda overlooked one new key feature, multi-display support for up to four independent displays on a single card, another first for Nvidia.

It is pretty much well known that the upcoming GTX 680 will feature two DVI, one HDMI and one DisplayPort output, but for the first time, Nvidia's GPU will be able to drive up to four displays at the same time. Another novelty is that Nvidia's 3D Vision Surround with full stereoscopic 3D on three screens will also work on a single card.

With multi-display support and boasts of good performance per Watt, Nvidia has certainly managed to surprise us this time around. [Yes, they borrowed a few AMD ideas, and now AMD will probably start borrowing theirs, like rebranding. Ed]
