That's another point to review.
Does a single 65nm GT200 with 1.4B transistors draw more, or less power than 2 x ~800 Million transistors at 55nm + PCIe 2.0 bridge chip...?

Of course they're trying to hide something, these slides are part of a NDA'd PDF file ! NDA means "Non Disclosure Agreement", right ?

Somehow i doubt they would try to hide something with Powerpoint or PDF presentations..., and then hand over the actual hardware so that websites around the world could test against (or in support of) those "official" findings by Nvidia, all this roughly two weeks before the NDA expiration date.

Reviewers guides are only under NDA until the product launches. Typically slides like this are not uncommon when presented to the press. I have seen it everytime I go to editors day.

Obviously, a typo.
Still, 6pin+6pin for a single GPU product that is supposedly cooler than 9800 GTX (at least the 65nm version, i don't know about G92b yet) ?
160W TDP for a GDDR5 card (wasn't lower power -or similar power envelope at high speeds- one of the main points of said technology) ?

It will be interesting to compare HD4870 X2 with both GTX 2xx in that regard, when the time comes.

How do you know Nvidia hasn't made significant advancements in this area as well? Idle power is an area of big concern for Nvidia right now.. so....____ + ____ = NDA!

It's not that simple, frequency and leakage among others make a big difference.

 

[ZerazaX]

Same for the process - if they're using the TSMC premium 55nm process there might be energy differences as well versus the old cards

I think using the two pins on the 4870 is meant for safety in case of spikes + OC headroom should be good

No magic deep inside GT200. GT200 is just about as the 8800Ultra X2.

excuse me, but as far as i am concerned, 2xg80 ultra is magic in a single GPU

two of them are .. well, the ability to play any game at 25x16 including Crysis satisfactorily and also to play any other game at 19x12 with max details and filtering applied .. that is real magic, imho!

Crysis wont even be playable at 1600X1200 with 4XAA if you go by the GT200 PR benches!

It would be about 20 FPS at those settings if you scale accordingly (~2X 3870X2).

Damn, gonna need some liquid nitrogen cooled over clocked SLI'd GT200s then...

That aught to do it!

Good to hear as I have plans for 2 280's if the reviews look good compared to AMD's offering.

Apparently the maxium power draw isn't.

 

[ZerazaX]

Well, ~240W TDP for GTX 280 and ~180W TDP for GTX 260 don't surprise me.
But a 160W TDP and the need for 6pin+6pin power plugs for HD4870 (non X2, mind you) does. It makes me wonder where a HD4870 X2 would stand, and if it would be that far from 240W too.

160W TDP for 6pin + 6pin actually makes sense IIRC because non PCIE2.0 slots only go to 75W IIRC (150W for PCIE 2.0) and each 6-pin is rated for 75W. So 1x6pin + PCIE 1.0/1.1 would only get you 150W and I bet they added the second one as a backup. IIRC 8-pin is good for 150W hence 1x6pin + 1x8pin + 75W slot will put you good for 300W, which is what GTX280 and R600 used

Maybe Nvidia uses NVIO for basic 2d operations?

The ES samples actually use more power then the release version of the cards now having said that, I'm not sure if we have seen pics of a final retail version yet, other then mock ups and coolers. If the retail version of the 4870 would need 2 6 pin connectors, I would be suprised with the noted TDP thus far.

With a 160W reference TDP 2x6 is needed, also partners want to offer OC versions.

All PCIe slots are 75W, PCIe 2.0 is not higher. Additionally its best to leave some margin on the PCIe connector.

15-20 fps is what i'm getting with 8800U on 175.16 drivers on Very High 1920x1200 AA 4x.
So i hope that G200 will at least provide near playable 25-30 fps in Crysis at these settings.
I also tend to think (from my personal experience) that 3870X2 is quite slower in Crysis in general than 8800U.

could some quickly tell me when theses cards are being released.

please I really need to know quickly. thanks

NDA expires at 6 AM PST btw.

NDA expires at 6 AM PST btw.

what is NDA ?

cool thanks can't wait until the 17th. im wanting to use the step up feature on my 8800gt to step up without spending more than $50. Are there estimated price drops about the current cards ? and what will the prices be for the new cards?

Thanks for the quick replies
