Nvidia today blows off the smoke out of the rumors surrounding the GeForce GTX 1080 Ti. This has been going on for weeks, and in a timely Nvidia fashion at GDC 2017, the card has been announced.
The GTX 1080 Ti is based on the GP102 silicon, which is the same GPU utilized by the Titan X Pascal part. With that said, Nvidia has to gimp the specifications to keep it in check at $699. What’s interesting though, is that they never touched the CUDA cores and instead, disabled one of the memory controllers. Leaving the card to feature 11GB of memory with a 352-bit bus width.

Physically, the GTX 1080 Ti 11GB Founders Edition features a better power delivery and thermals compared to the FE cards that came before it. For an instance, the DVI port has been completely removed allowing for a better ventilation area. AIB partners are still welcome to add DVI ports though.
Power on the other hand saw use of dual-FET design, with a 7 phase VRM receiving two FETs each. This allows the GTX 1080 Ti to half the current draw per phase, and to efficiently spreading the heat to the modified base plate of the card. Ultimately, the card features 8+6 pin PEG power connectors with a maximum budget of 250W.
Performance is still hidden deep in the murky waters since Nvidia only had a comparison with a GTX 980 at the moment. Still, we are expecting a 35% increase of performance over the GTX 1080.
Finally Nvidia will open up the pre-order of the said card by March 2 and will be available everywhere on March 10 at 10 a.m.
