G80 pics - Talk about it here.

[nemecb]

Heh, the speculation is just flying over these pictures.:)

Can't wait for this to come out. Will be nice to quit limping along on my 6600GT and be able to really play at my widescreen's native resolution with some image quality. Then again, it's probably close enough now that I could just buy an eVGA 7900 and step up...hmmm...

[retsam]

Hrm!

I wonder if that 1.5GHZ clock is actually the combined clock speed of the two cores (if there are two cores)

Doesn't nvidia say the 7950X2 has 1GB of Videomemory, but really it only uses 512MB

Also I hope the watercooling card comes with its own pump...if not they must really be targeting the Extreme High End!
well doesnt the g70 have clock domains? i mean couldnt this just be one of the domains with a very high clock?

[Redeemed]

My understanding of the 1.5Ghz number is that the clock can run up to that speed- yet that doesn't mean that is how fast it will run.

I'm betting the refresh might actually run close to that speed, but definitely not the 8800GTX. I'm betting the 8800GTX will be around the 700MHz range.

Might be like how the Pentium 4 was supposed to scale to 10 Ghz?

[retsam]

did anyone else notice that the sli connector hasnt changed? im willing to bet that nvidia hasnt made any changes to sli at all.

[CaptNKILL]

Wow this thing scares me.

I'm intrigued.

I want.

Oh, and why did they take pictures of the heatsink alone and not the bare card? Thats what I want to see...

Exactly. ;) And, as we all know, we'll never see a Pentium 4 at 10GHz. :)

Do they really need too?

[Redeemed]

Do they really need too?

In my opinion, no.

[tweaked]

NEED TO?

no, but one would hope for improvements in all areas.

of course this means no new sli problems.

I haven't had any SLi problems yet. So I'm quite pleased with the way it works now.

The question is if the SLI bridge might ever become a bottleneck with advanced (DX10) games on these new cards. I´m not sure what exact data is moving through the SLI bridge but maybe thats what retsam had on his mind. :confused:

I hadn't thought of that. But I'm sure that nVidia has, and I don't expect it to be a problem with the G80. Maybe the current bridge would be a problem for the G90, G91, or G100. But I'd be surprised to find it a "bottleneck" for the G80.

hmm I've never thought of anything like that. Are there min performance differences between lets say.. Two ATI X1600 in crossfire and one of those dual GPU x1600s?

No real bandwidth extensive data is sent through the SLi Bridge, I dout were anywhere near the bandwidth limitation of it. Most of the heavy data is still sent through the PCI-Express ports.

[agentkay]

I know that SLI and CF are sending data back and forth through the PCIe bus as well, thats why CF´ed x1600 didn´t need a dongle (AFAIK) but CF´ed x1900 did. I think its the same with SLI, where the low-end cards don´t need a SLI bridge since PCIe has plenty of bandwidth left but as cards get faster, they need the extra connection.

When I thought of that pattern and that the G80 might end up twice as fast as current high-end cards, I also thought that the SLI bridge might become a bottleneck.

It was not necessarly a concern, since I´m fairly certain that Nvidia knows how much traffic the SLI bridge has to deal with.

Is it true that a single gtx version of this card can outscore dual 7900gtxs in 3dmark.

A few weeks ago there were rumors that a single G80 would be twice as fast as a single 7950GX2 card (around 7500-8500 points in 3Dmark06).

Yup. But rumors about these new cards also imply that the they will need tons more bandwidth that the current generation. I am of the opinion that we wont need a new SLi bridge, but I do think that if video cards keep up with this current trend then come G90 or at the latest G100 we will need a revised bridge.

Only a little bit of information is shared across the SLI bridge :)

well, i was hoping for a surprise with sli. maybe something along the lines of memory spanning(the two cards seperate memory looks like one) or some sort of new way todo AA/AF.... i guess one will see soon enough.

yeah i was hoping for memory spanning too. The bandwidth between the cards would have to be HUUUUUUUUUUUUUUUUUUUGE, and SLI would have a new/different implementaion.

that would mean 6 months of refinement making it work well.

for now i can accept plain ol SLI that just works!

SLi data for AA or AF don't remember which one, already travels over the bridge, this was introduced with the 7900's, the bridge connector really doesn't have to change, it just provides increased bandwidth between the two cards. AA and AF performances are greatly improved on the g80 and there are new modes for AA.

[AthlonXP1800]

I think I will probably get Geforce 8800 GTX card, the card size judged by the pictures look like 1 inch longer than Geforce 7800 GTX card, I am glad Geforce 8800 GTX will fit in my case. :D
