R600 Installed

:roll: We've been over this before. It's impossible for the R600 to pull 300 watts.
PCie slot - Provides 75 watts maximum
6 pin PCIe power connector - Provides 75 watts maximum
8 pin PCIe 2.0 power connector - Provides 150 watts maximum
That's a total of 300 watts maximum. No computer component has been or will ever be designed to draw the absolutely limit of power that is possible to be supplied to it.

No, that would work. It's possible, but every picture we've seen so far has shown either 2 6-pin connectors or 1 6-pin and 1 8-pin.
In one of the threads here, there was a quote saying that the R600 would work with 2 6-pin connectors, the same as the 8800GTX. But doing so would disable the factory overclocking option in the driver.
Whether or not this is true is anybody's guess.

Length & wattage are completely irrelevant to me. Show me benchmarks and give me a price as that is all I care about.

exactly.
No SLI-like connectors?
Well, at least it doesn't have a dongle...
Two GTS 640 MB's would be perfect if nVidia new how to get their own SLI working properly.
So far 2007 has been nothing but troubleshooting and waiting it seems.

I'm deeply concerned by the amount of emphasis being placed on R600's number crunching ability rather than its pixel shading capability.
Exactly why do we enthusiasts care that R600 crossfire can push a teraflop?

The 2 cards used for "Stream Computing" do not use Crossfire. 2 8800GTS 640MB's are quite nice for the most part now, just a few application issues with SLI interfering with my happiness.
@Matt2, over at XS they drool over Folding@Home etc so some enthusiasts do care.
@Creig the GPGPU based on the XTX can have up to 4GB of VRAM so I can see that hitting ~270W possibly.
While were talking about old news i found these specs of the r600...

32 ROPs

512GFLOPs for the shaders
2 Billion triangles/sec

Actually, you just confirmed that it "is" technically possible for an R600 to pull 300W. You added it all up for us and everything. Not saying it does pull 300, but it could.
And I bolded all the presumptuous remarks. You cannot know what "will ever" come out in the future. Why do you think power bricks are sometimes considered? Because they are fearful that the product will pull more power than the system can provide.
If it uses 300w, doesn't that bode well for its performance (more than likely anyway)?
AMD recently stated that it will only use 200w. This news doesn't make sense.

I doubt it will be 65nm.. AMD hasnt even got processors on 65nm yet afaik, i would think they would concentrate on getting those out the door first before getting a video card on a 65nm process. 80nm is more likely
It's a good thing you're not an engineer with thinking like that. Variances between cards (some draw slightly more, some draw slightly less), variances in heat can cause increased/decreased resistence, etc.
For the same reason nobody runs a system with a PSU that puts out only enough to run the components in the case, no company will design a component that pulls every last watt available to it. Every item in your computer has a certain "safety margin" built into it. Why do you think it is that video card companies put out a high "recommended" PSU requirement, yet the actual recorded draw during private testing is always lower?
I do know for a fact that nobody will ever design a component to draw max power available. That's just asking for instabilities. It's the same reason power bricks used to be considered. When video card draw was outstripping available PSU power they didn't want to run the risk of system instability. So adding a power brick would alleviate that problem. And I guarantee that the amount of juice that would have been supplied by the system+brick would not be exactly equal to the system draw. They would have given a healthy amount of free overhead.
