The belief is that it will go out under a “Titan” branding, and could be a doubling of a fully-unlocked Titan X.
If that is correct then that would mean both GPUs would feature 3,072 CUDA cores, 192 TMUs and 96 ROPs, with 12 GB of GDDR5 available to each GPU through a 384-bit bus.
Question is whether 6,144 CUDA cores and 24 GB of memory ever going to be enough? For a start half the memory will be duplication as only 12 GB would be available to games.
No one is confirming the rumour. Nvidia might opt for a dual GTX 980 Ti setup instead, or it might just go to the pub and forget all about it. That is the thing with rumours.
Like with all dual-GPU cards from Nvidia, it will perform identically to having two separate graphics cards connected in SLI, as the dual-GPU card uses SLI to connect both GPUs.
The advantage would really be in cooling which tends to be a bit better on dual-GPU cards compared to traditional SLI setups.
We expect that when you plug this in all the lights in your street will dim and there will be a manic cackling from your power company as it calculates your new bill.
Nvidia’s dual-GM200 graphics card will reportedly be launching very shortly, although the price hasn’t been revealed just yet. Nvidia last dual-GPU card, the $3,000 GTX Titan Z, was considerably more expensive than simply buying two single-GPU cards and hooking them up in SLI. Only the stupid bought it, and there were not enough of them to go around.
