It appears that patience has paid off for those who have been waiting patiently for the NVIDIA GeForce GTX 1080 Ti, as leaked specification shows that the much anticipated graphics card features a whopping 12GB GDDR5 memory, 3328 CUDA cores count and is based on the same Pascal GP102 GPU used on the Titan X Pascal. 
As for the memory, the GeForce GTX 1080 Ti will not be utilizing GDDR5X memory, but GDDR5 instead with 8 GB/s Memory Speed on a 384-bit bus and a total memory bandwidth of 384 GB/s. It’s a significant downgrade on the memory, but our assumption is that NVIDIA doesn’t plans to have the GeForce GTX 1080 Ti to cannibalize the Titan X Pascal, given that it’s using the same GP102 GPU and AIB partners will have their own variant of the GTX 1080 Ti that comes with a high clock speed and can easily go on par with the Titan X Pascal even if it has 768 less CUDA core count.
GPU wise, we can expect the GeForce GTX 1080 Ti to utilize the Pascal GP102 GPU with a total of 3584 CUDA Cores clocked at 1503MHz and boost clock of 1623MHz that can easily overwhelm the GP104 with 2560 CUDA cores even if it comes with a higher clock speed of 1607MHz and boost clock of 1733MHz.

Just like the Titan X Pascal, the GeForce GTX 1080 Ti will require a 6+8 pin power to run and features a total TDP of 250W.
