When NVIDIA announced the GeForce GTX 1080 Ti it pretty much cannibalized the TITAN X Pascal. In doing so NVIDIA needed something faster to sell at their $1200 price point. Well without really saying much about it they have launched the new TITAN Xp, and in doing so have discontinued the TITAN X Pascal. The new TITAN Xp feature all of the 3840 CUDA cores than are on the GP102 silicon, all 240 TMUs, all 96 ROPs, and 12 GB of faster 11.4 Gbps GDDR5X memory over the full 384-bit wide memory interface.
This is compared to the 3584 CUDA cores, 224 TMUs, 96 ROPs, and 10 Gbps GDDR5X memory of the TITAN X Pascal, as well as 3584 CUDA cores, 224 TMUs, 88 ROPs, and 11 GB of 11 Gbps GDDR5X memory across a 352-bit memory bus, of the GTX 1080 Ti. The GPU Boost frequency of the TITAN Xp is set at 1582 MHz. The card is going to be sold exclusively through GeForce.com.
