G80 naked with mystery chip

unless something changed, in the leaked release documents it says the G80 will come with a PPU, I bet you that is the chip for it

Yep, at least there is someone here with a good explaination. I have a 7800 GS and it has a PCI-e to AGP brdige chip on it. The 8800GTX wouldn't need one of those though, so it must be for physics.

Yea, it must be. Nobody knows what it is except the people at Nvidia that worked on the thing. Speculation isn't truth.
 
looks like a geforce 2 chip, so you could play all your vintage games on it to !! ;)
 
too big for DRM/HDCP purposes, nvidias physics implementation will most likely be a separate PCI-E card. IMO it could be one of the following:

1) Onboard Physics
2) Some kind of compatability chip for DX9 or below games.
3) HD video Decoder/accelerator or something similar.
4) A switch/processor/bridge for the physics PCI-E card.
5) Embeded memory for AA/AF
 
my GOD i have been looking for this picture for 2 MONTHS. and its HERE. and its SWEET.

but umm one question for OP, wtf is DRM?

edit: and i knew it was going to look funky, this explains the two pci-e connectors. two dies, two connectors, each of them just want some love.

this was my guess also. it's the "oh shit, SLI is b0rked" chip.

sooo excited now man. seen the boxed ver from asus, seen the board, now OCP its time for you to rip it apart and give me some specs

altho kyle said "overclocking the G80 is like a pale full of [something, cant remember exactly what he said... but it sounded good]" so.... so happy :D

No, it is a PCI-E -> AGP bridge chip, as there will be AGP versions of this card. Nvidia has heard the cries of all those folks refusing to leave the 20th century, and allowed them to run an 8800GTX on their Athlon T-bird systems. It also handles re-combining the video output from both cards in SLI, as Nvidia has decided to go with an external dongle solution.

There will be no 8800GTS for AGP, since G80 is PCI-E native why the hell would they use a bridge chip on the PCI-E version of the card? AGP versions may well appear however they will not be 8800GTX/GTS's and definetly not now.
 
lol.. but why would it need a seperate chip for doing DX9 stuff.... Do our current boards need a whole dedicated chip the size of a US quarter to do DX7 stuff? I thought direct x was just software that used the new hardware capabilities to help render the graphics. (shader technologies, etc) If so, it would be backwards compatible easily since the chip would be powerful enough to compute everything the previous generations of cards could do.

The chip is there so you can run embedded Linux on your video card to handle the new DX10 functions .. nVidia calls it the 8800KILLERgtx ... they're still working on a "K" shaped passive cooler for it tho ... I just read that over at the INQ

omg i about died laughing when i read that... as its already been said, i think its something to do with embedded physics processing of some sort, why else would there be odd specs, like 512 + 256mb of video memory and a 256bit + 128bit memory interface. to me its obvious there is two separate computing systems on this card, one is a 512mb GPU with a 256bit memory interface and then an unknown 256mb + 128bit memory interface, which also doubles as additional horsepower for GPU stuff when needed.

my guess is that when nvidia releases some sort of physics solution these new cards will work with the additional 256mb + 128bit system.
 
I'm thinking now it has something to do with the new dual rail SLI, or dual channel SLI.

It also enhances the size of your penis and makes you last longer in bed. Apparently you didn't get the joke... :)
 
yeah thats what im thinking too. been looking alot recently at expected numbers, they all give the odd bus and the odd ram.

they also mention the seperate "geometry function", that was just a function of DX10, and on the integrated shader model.

maybe Nvs pushed the idea a little further, givin it its own bus and memory, and now makes it not only render the polygons, but smash em together too.

You might be onto something there. Maybe SLI for dual or dual link monitors now? Compositor/hardware antialiasing chip anyone?

the memory bandwidth has gone up by 50%, since thier using only slightly faster memory than the current 7900GTX, the higher memory bandwidth must be from the wider memory bus meaning it isnt separate.

dont buy that, its just to weird a number.
 
I vote for HDCP.

The sli and media stuff is going to be on the main die, HDCP is the only external functionality we're going to see on these.

Outside chance: Rage Theatre replacement, for improved vivo/purevideo.
 
SLI is on the main die.. I remember that... since the 7800 series on up.. but they also said SLI was not working well.. so it might have needed something.. well, I still think it's a pci-e --> agp bridge chip.. for the agp version.. notice it's only on the 8800GTS, the lesser version...which will be the only agp version..

or wait.. I didn't notice the 'keep out' thing before.. lol

pretty sure the first photo you posted is photoshopped, one of the other GTS photos had the memory chips blacked out and both pictures of the naked boards have that "keep out!" thing written... kind weird but i think the keep out is illegit
 
it gives the main gpu just enough power to simulate time travel. so u could play half life with gordon freeman as a 9 year old boy
 
christ thats a huge main die, is that an IHS on it?

Why the second SLI connector? bottleneck alredy?

The 7950gt has HDCP support, but I don't recall seeing an extra chip...
 
oh em eff gee. The new 8800GTO with the chip revealed. It appears to be an AMD FX-62. It needs a little more power too.. and dual SLI links.

^^ lol

The second SLI connector is for dual rail SLI. "The Inquirer" just released another set of info about it. It can read/write at the same time or something. http://www.theinquirer.net/default.aspx?article=35318

full duplex data flow. what a concept. ;) but that is good.. SLI performance should continue to be tuned and improved both in hardware and in software. Nice stuff.

EDIT: but the old function of the bridge was just to send the video data over to the frame buffer card for final assembly.. I didn't know there was a lot of need to write data back to the "slave" card - but oh well.. I guess having seperate data paths would be more optimal..

haha nice photoshop ;) and the only question is "can you overclock it?" :rolleyes:

So the 8800GTS needs one power dongle while the higher end one needs two?

And, according to another picture, the GTS will only have one SLI connector on the board, while the GTX will have 2.
 
Maybe the GTX is the only one with the physics chip, and the second bridge is for physics data? SLI QUANTUM PHYSICS

/rampant speculation

How do you get 640MB out of 12 RAM chips? (see 8800GTS). Perhaps 8x64 + 4x32?
Click to expand...
512 normal video ram, 128 dedicated to special tasks like AA. ^_^
 
Man, the only reason I clicked on this thread was because I thought the title was, "G80 naked with mystery CHICK!!!" What a ripoff....:D
