The specifications of the GTX 1080 Ti are expected to be similar to the Pascal-based Titan X, but with fewer CUDA cores.
NVIDIA's new GeForce GTX 1080 Ti will reportedly rock most of the same specifications as the Titan X, so we have 12GB of GDDR5X being used at 10Gbps on a 384-bit memory bus that will provide 480GB/sec of memory bandwidth. NVIDIA's purported GeForce GTX 1080 Ti will have some CUDA cores shaved away, down to 3328 CUDA cores from the 3584 CUDA cores on Titan X. The GP102 GPU used will be clocked at 1503/1623 for Base/Boost clocks, respectively - providing 10.8 TFLOPs of compute performance, all with a 250W TDP. So we're looking at a very close competitor to Titan X, but cheaper.Titan X will remain the performance king, but this new GTX 1080 Ti is expected to launch at a much cheaper, but still very expensive, price tag of around $899. Guess we'll learn more in the coming months if this rumor pans out.
