NVIDIA GeForce GTX 980 Ti 6 GB @ techPowerUp
 

Today NVIDIA releases the GeForce GTX 980 Ti, based on the same GPU as Titan X, with same clocks but fewer shaders. This card is designed as preemptive strike against AMD's upcoming Fiji cards. In our testing the $650 GTX 980 Ti can almost match performance of the $1k Titan X.
