only 1 core? I thought the 9800 was physicly two 8800's, so its a dual core chip

^Yea, same thoughts here... "why only one GPU?"

no they didn't put both cores on the same PCB. The PCP is bolted together then runs on one PCI-E slot.

There isn't a shot of it put together.

Bit confused on that now too except I thought it was a 2 PCB layout so I think they must just be showing one. If you look at the 3rd pic it appears to have the bridge for the 2nd PCB.

They left the other PCB on the heatsink by the looks of it. Pics do not show on that other site for me so maybe they show it there.

Yes there're two PCBs, but pictures show them one by one...so that makes the illusion that there's only one core. I'll add the second PCB (pic) in a few minutes.

I take it then each pcb fits onto each side of the cooler. (kind of like sandwiching (SP?!) the cooler?!)

Wow, since the release of the HD3870 X2, it's now NVIDIA's turn for all the viral-marketing drama (pre-release reviews, Mysterious pictures, etc.) Just to make people interested in the product :rolleyes:

Wonder if temps are going to be an issue with the cores sandwiched? Aftermarket cooler/waterblock makers will have their work cut out for them on this one (if even possible).

Pics #2 and #3 are two different PCB's. The second PCB has no PCI-E expansion interface.

So the cores face eachother, and the cooler is placed in between. I like this design a lot better than the 7950 GX2.

It have 2 PCB's it's going to be sandwich, 2 PCB's & a fan & Heatsink between them. very tasty :)

the idea is great but we have to wait and see real temps and other numbers once this thing gets reviewed .............. but on the other hand ATi did a better job just putting 2 cores on one pcb , i gues nvidia is just to lazy to do that instead ....... just my opinion . :cool:

haha... maybe true... Cant wait to see how this stacks up against the 3870X2... seems like Nvidia may actually have some trouble with this one, as SLi doesnt scale as well ... Personally I would rather have seen a signle chip solution... like a 9800GTX with 256 SP's but that may be asking for a bit too much atm.

There are ups and downs to both setups. With ATI's design, one core is getting cooled by the hot air from the other core. So one core is guaranteed to run a lot hotter than the other. The other option is to use two heatsinks and fans, but then the hot air isn't being exhausted out of the case, which is also bad.

I don't really think one disign is really better than the other.

3870 X2 wins in the aftermarket cooler part, this you can't even put pack together after you dismantle it, there's going to be that one left over part :D But can't they not use some quality thermalpads and not that gooeyfibrestuff on the high end model at least :/

That sandwich idea is indeed tasty. Comes with instructions:
  1. Remove packaging
  2. Heat up 30min with favorite FPS
  3. Enjoy the crispy silvery taste

shouldn't the bolting holes from the 7950GX2 should carry over

This should actually be easier to watercool compared to the 7950GX2. With this you can just use on sandwiched waterblock. And from the looks of the stock cooler, it shouldn't be too hard to build a waterblock that fits in that space.

Yeah, now that I have a second look at it, it may be easier to WC this thing compared to the 7950's. It looks like it may be difficult to take appart/put back together without undue damage/scratches to the outer shell (thinking for warranty purposes, if you have any issues with the card).
