已經delay左好耐.....而家仲delay多6個月
paper launch
4月12日先有貨 (>10000 pieces)

HD5850 < GTX470 < HD5870 < GTX480 < HD5970

不過 470都叫勁過5850 咁都算有dd交代啦
如果12月出就係lor, 而家4月都來緊啦

不過ati一打降價戰佢就:rip:
AMD唔駛打價格戰啦, NVIDIA都俾唔到壓力佢
唔好唔記得一唔夠貨, GTX4x0又要加價

So after reading a good dozen or so reviews I think I have a decent summary.

GTX480
+Price / Performance level very near 5870
+Price is fair in regards to price based on the available alternatives (again point 1)
+Indisputably faster than the 5870, often with noticeable better minimum framerates
+Respectable clock headroom ( although I didn&#92;&#39;t see enough info on the increases in power / noise at overclocked settings )
+Very nice SLI scaling with 2 cards for a new release

- 100watts more power draw at load over a 5870 ( a common figure in reviews )
- 25watts more idle draw ( not terrible but not impressive either by any stretch )
- Hot as the lava in metroid ( pure pwnage reference )
- Loudest reference card
-Underwhelming performance at 2560x1600 ( although there are multiple mentions of this being driver related... which strikes me as odd )


So assuming they don&#92;&#39;t combust down the road ( of which Nvidia attest to not happening... ) if you have the power supply, cooling (ie adequete case) and money and don&#92;&#39;t mind the noise, the 480 is a decent card @ its intended MSRP. Now there is still the question of availability and potential price gouging.

All that said, a 512sp part on a smaller node would probaley be epic. Now wether we can expect to see this before ATI brings out a new line... doubtful. And as far as a dual gpu part, all I can say is good luck. Given Nvidia&#92;&#39;s claimed TDPs are easily reached ( quite interesting ), they&#92;&#39;d have to pull some serious voodoo magic to manage a dual gpu card that works AND makes sense at its price and performance level ( a very difficult prospect I&#92;&#39;d say )

不過見佢果d dx11

好似好勁咁wo
呢樣係GTX480強項

要睇DX11普及速度快唔快
照睇應該幾快, 對GTX4x0有利

不過年尾AMD又出Northern Islands
到時又唔知會唔會反超前
(Evergreen係無誠意之作, shader cut得又多, shader performance又低)

wow guess NVIDIA went way overboard with their GPGPU concept...

I&#92;&#39;ll only wait for low power laptop GPUs...lol
I think Fermi is not over-stress on GPGPU.

Forced by AMD and Intel, NVIDIA is shifting from a GPU company to a GPGPU + Software company.

As a GPGPU card, its performance is unquestionable. Being faster than Evergreen family with a large (multiple times) margin in OpenCL / CUDA applications, Fermi establishes itself as a hot GPGPU card. I can bet on Fermi will gain a large success in HPC / Professional graphics / GPGPU applications.

As a gaming card, I would only say I am disappointed as GTX470 is slower than HD5870.
100W more power-hungry also counts.

yes what I was saying is NVIDIA spent too much resource on GPGPU aspect. And they missed on the gaming aspect.
I don&#92;&#39;t know why NVIDIA chooses to use 1 single GPU for gaming + GPGPU applications.
Fermi for GPGPU and Fermi for gaming (gaming does not need DP programmable shaders)

Although RV870 is only decent in GPGPU applications, AMD still manages to cut RV870 to less than half for RV840 WITHOUT GPGPU enhancements.

無誠意 效能高就夠
不過5830就真係
就係咁先慘, AMD係賺到笑

hope NVIDIA can do well in GPGPU field and give us a better revision of Fermi....
You may better count on Intel for better GPU (Larrabee Generation X) for coming 5 years.

NVIDIA will not focus on gaming anymore.

I don&#92;&#39;t think NVIDIA will give up gaming market THIS easily.
They still need this to push their PhysX.

And for Intel....I&#92;&#39;ll believe when I see it...
PhysX is the saving grace for NVIDIA GPUs.
Many people just buy NVIDIA GPUs because of PhysX.

Then they need to preview the PhysX is doable with their own chip.
They are not a complete software company at least now.
You will need some time to show you are a software company.

NVIDIA is certainly heading this way and this is the best thing they can do against AMD / Intel&#92;&#39;s GPU invasion.

Sidenote:

Fermi boasts exceptional well CUDA / GPGPU / Tessellation speed.

講真,所取所需姐
4系既卡仲係度,要CP可以買番佢地
想慳電可以買5卡
老老實實NV唔出DX11卡根本唔洗旨意等玩DX11 GAME,連3DMARK都要等埋佢......
5卡準時到達可以比人試住玩住先既
唔通好似NV咁8800走天捱咩 ...
RV6x0 / RV7x0好似清哂貨

Evergreen我又覺得不算無誠意,效能其實也可接受 (expect 5830)
係你無睇in-depth定點

我唔知你點睇, 但我覺得:
1. Shader performance無理由下跌 (Rv8x0慢10%)
2. US$400同US$100 Shader數目相差應該係一半左右 (RV830係RV870的25%)
3. US$150同上代US$300效能應該差唔多 (HD5770慢HD4870超過10%)
