Joke or not, I can't see the connection your making. My ISP honestly can not find the site. I can get there now though with the manual settings.

I was jokingly suggesting that they blocked the site for its anti-Nvidia bias. It could be an error or it might just be someone doesn't like charlie (he has a way of making lots of enemies in the tech biz).

I wasn't doubting you if that is what you were thinking.
 
What update are you hoping for exactly? Cards are out, you can buy them, reviews are available and this thread has run it's course.
 
Dont know if its posted, but its only 10% faster than the Gtx 480.

Radeon HD 6970 (Cayman XT) 3DMark Vantage test results floating around in the X12000, but P mode is P24499. 在Unigine Heaven (1920 1200 4AA+16AF)环境设置下运行速度为36.6帧。 In Unigine Heaven (1920 1200 4AA +16 AF) environmental setting speed was 36.6 frames.

HD 5870 3DMark Vantage获得P19337的成绩，在Unigine Heaven (1920 1200 4AA+16AF)运行帧数为17.3 。 HD 5870 3DMark Vantage P19337 results obtained in Unigine Heaven (1920 1200 4AA +16 AF) running 17.3 frames. 同平台下GTX 480 3DMark Vantage获得P21106和X9309的成绩，在Unigine Heaven (1920 1600 4AA+16AF）速度为29.5。 The same platform GTX 480 3DMark Vantage P21106 and X9309 results obtained in Unigine Heaven (1920 1600 4AA +16 AF) speed is 29.5.

毫无疑问Radeon HD 6970(Cayman XT)将会是单卡之王 ，在相同状况下超出GTX 480性能10%以上，从测试中来说具备压制性的实力。 There is no doubt Radeon HD 6970 (Cayman XT) will be the king of a single card in the same circumstances beyond the GTX 480 performance above 10%, from tests run with oppressive power.

不过这张卡依旧是内部样卡，板型类似5870，核心频率在800MHz－900MHz范围内，供电接口为6+8，相信TDP应该在255W或者以上。 However, the card is still within the sample card, similar to plate 5870, the core at 800MHz-900MHz frequency range, power supply interface is 6 +8, I believe should be 255W TDP or more

6+8 is same as GTX 480 - and TDP of 255W is higher than the GTX 480.

Not when the 480's TDP is kinda bullshit.

Read this thread which explains a fair bit of it, actually started by myself:

The chart above shows that, for the oficial information specs from nVIDIA and AMD, the GeForce GTX480 should drew less power than the Radeon HD5970. More precisely, the GTX480, according to nVIDIA, draw 15% less power than the HD5970.

However, the data from those reviews, observed that in practice, the GeForce GTX480 consumes 2.17% more energy than the Radeon HD5970. That is, although you know your nVIDIA card consumes less than the AMD, the reality is that, in fact, it consumes more.

Therefore, it is evident that the value of maximum power consumption reported by nVIDIA contains some ambiguity. However, we can estimate the correct value, which would, by logic, 2.17% higher than that of AMD Radeon HD5970. Ie: the TDP's GeForce GTX480 would be the HD5970's TDP, plus 2.17%. Doing the math:

TDP [GTX480] = TDP [HD5970] * 1.0217

How does the HD5970 TDP = 294, then:

TDP [GTX480] = 294W * 1.0217 = 300.37 W

That is, although the nVIDIA inform you that the maximum power consumption of your card GeForce GTX480 is 250W, the reality shows that this number is greater than 300W. The fact that TDP is more than 300W is a complicating factor and so, considering that PCI-e used for such cards have a maximum of 300W spec.

So, if the technical specification of the official nVIDIA indicate a 300W TDP than that, it seems reality is, there would not be recommend the installation of a GeForce GTX480 in the motherboard's available on the market right now.

It would, in fact, that manufacturers of motherboards make new cards, with enhanced specifications to support a GTX480.

Conclusions

Comparison of the results of power dissipation of the reviews of the GeForce GTX480 with nVIDIA's official figures show that something is wrong with the official figures from nVIDIA. It is not possible that a board [GTX480] with lower TDP official consume more than another which has a higher specification [HD5970].

If the nVIDIA used the AMD method for informing it´s TDP, is likely that the TDP's official GeForce GTX480 would be above 300W. In this situation, the board would fail to be officially used in PCI-e that exist in motheboard's, which would not allow its commercialization.

The solution in this case would be the nVIDIA or reduce the frequency of operation of the GPU, or the amount of shaders. In both cases, however, the performance would be compromised to the point of the plate show a lower performance compared to AMD's Radeon HD5870. The problem is that Nvidia promised that its board would be faster than AMD's, so therefore, this solution was probably discarded.

Or maybe AMD is over-reporting the TDP of the 5970 for some reason. It could be either way.

The sums don't work that way.

480 quad SLI uses 1500W+ under load.

250W TDP = 1000W, so no idea where 500W is being used...

5870 4 way doesn't chew through that.
 
Well I got a Gigabyte 6850 today, idle temps are about 34C and load temps are around the mid 50's which is quite impressive, reading other reviews the reference card hits around 70C+ under load. Pretty impressed with the 6850.

With the Windforce2 cooler? Are you stressing under Furmark as well? I've been contemplating that one vs Sapphire version. HardwareHeaven and SweClockers are the only places I've found that have reviewed both versions showing similar cooling performance.

One review shows Sapphire better by 1 degree and the other shows Gigabyte better by 2 degrees, but damn your temps are impressive!
 
^^ Yeah with the Windforce cooler, looks so good, and since I'm a Gigabyte fan I could not resist. Haven't stressed it under Furmark yet, will try later and post my results. Only tested it under games like Far Cry 2, Lost Planet 2, Street Fighter V and Devil May Cry 4 and temps were the same.

You overclock it? :D
 
^^ Nah, not yet, have no experience in overclocking video cards whatsoever.

Also, my Furmark temps was at 69C maximum, which is alright. Would have hated if it went over 70C. Nice job Gigabyte cooling this card.
 
Those are the temps of my 2 480 in SLi on air in gaming. Im doing good on my air cooling setup.

Unlock OCing functions. Move slider to right. Game. If stable > Move slider more right. If unstable > Move slider to the left. :p
