GTX X2 coming?

IF it does come my guess is 2xGTX260 performance or basically 4870x2 performance. I can't fathom them being able to make it 2x280 due to size, power restraints but I could be wrong.

I moved this thread from CPU's, as it belongs in the video forum. I forgot to put a comment in your post first.

Wonder if they'll put it on a single PCB or go the sandwich route?

Oh shoot sorry I thought I posted in Video. Thanks.

Good question...considering the memory bus size and size of the die itself it might be better to go sandwich a la GX2?

Would 55nm open up single pcb possibilities? nVidia is experienced with the sandwich cards though. Seems they'd go with what they know. Will be a good card in any case. One thing I love about nV is the decent scaling. Should be interesting..

nVidia's got better scaling because they bought up 3Dfx and their SLI technology and they've had alot of time to tweak it. ATI had to do their implementation by hand.

They're already using a 14 layer PCB due to the routing necessary for the 448-bit memory bus. Even though the GTX280 is built on the same PCB with a 512-Bit memory bus, I doubt there's enough room left over to add the necessary lines for tying a second GPU into power, memory & PCIE slot plus adding an NVIO chip and ITS traces. My bet is the sandwich style as well.

I am surprised it has taken this long for something to compete on the top end. There must be some hold up on the 55nm chips.

Umm, no. 3Dfx only ever used SFR (Split Frame Rendering). nVidia and ATI both use AFR. nVidia tried SFR with their cards years ago, and for whatever reason, decided not to use it. So actually, all nVidia got out of the deal was being able to call two cards pushing one monitor SLI. You're right about the reason nVidia used to be farther ahead in scaling, though. They did start way sooner than ATI, but mostly just because they had more money to sink into the technology, I'm pretty sure. BTW, with alot of games these days, the ATI cards are scaling as well as the nVidia cards, and better sometimes.

SFR might see a resurgence... Lucid Hydra anyone?

Regardless of if they do it or not, I'm not sure that many people are going to want to pay for it! No doubt, if they managed to make a 280x2, it would be one bad ass card (heck... 260x2 would be a nice piece of hardware too). I sure as hell wouldn't want to see the price tag on a 280x2 though! 260x2 could be fairly reasonable (or as reasonable as you get for top end hardware).

That being said, at the rate these cards are growing at (size wise), they are going to have to start building parts of them in 5.25" enclosures and connecting them to the main "card" via cables.

Wuzup: Hey Zap, cute little computer tower you have there.
Zap: Nah, that's my computer.
Wuzup: Really? Then what is the big tower next to it?
Zap: That's my video card.

that is a lot more advanced then SFR... it doesn't split the frame, it splits the individual calculations.
