Features and a specification list on the GeForce GTX 1080 Ti just surfaced on the web (from an unconfirmed screenshot). It seems that the spec list has been showing on GeForce.com or something. The card would get 12GB GDDR5 graphics memory and more shader cores compared to the regular 1080.
The GeForce GTX 1080 Ti will be using the GP102 silicon, similar as used for Pascal TitanX, however it has 4 out of 30 shader processor clusters disabled, so that is 3,328 shader processors. If you do the math then your TMU count would get to 208 with a ROP count of 96. According to the screenshot the GPU itself will be clocked at 1503 MHz and 1623 MHz on the GPU Boost. Two things really jump out here, the memory remains GDDR5 not GDDR5X as Pascal Titan X is using and then the shader count has been decreased towards 3328 shader cores, which is still 768 more compared to the GeForce GTX 1080. This information surfaced on the web through users Excalibur50 from the OC3D forums, kudos to them for this find. I charted up the specs so you can browse back and forth a bit in order to understand the differences. That is going to be a very spicy card alright.
** UPDATE, after further examination of the screenshot (click the thumbnail at the bottom), we think it was tempered with, this information looks to be FAKE as far as I can tell. Look at the 3328 CUDA cores in the screenshot, you’ll notice that 28 is placed lower in there compared to 33.

GDDR5 memory would bring in 384GB/s of memory bandwidth, which would be the deal-breaker over a Titan X with its 480GB/s of bandwidth. It is still more then the 1080 though. The card will get a 250 Watt TDP. Pricing wise we know nothing of course, but the 1080 is at 699 USD, the Titan X at 1200 USD .. so somewhere in the middle ?
When the card is to be released we do not know, but we do know winter is coming … (if the screenshot below is not fake of course).
