TPU came across rumors that NVIDIA's GeForce GTX Titan-Z is still on the way and that NVIDIA needs some time to optimize the drivers to squeeze more performance out of the card. Whether NVIDIA will succeed remains to be seen, at present the GeForce GTX Titan-Z gets beaten in many tests by AMD's Radeon R9 295X2 - which cost just half as much as the Titan-Z.
When tested with ones that do, performance numbers yielded by Hong Kong-based tech print magazine E-Zone, reveal that the card trades blows with AMD's R9 295X2 in too many tests to warrant double its price at $2,999; and that it's also slower in some. The only way NVIDIA can sell the GTX TITAN-Z at that price, is by either making it significantly faster, or reducing the price. It looks like NVIDIA is trying the former, and not by tinkering with hardware specifications, but drivers. NVIDIA believes it can yet salvage the $2,999 pricing of the GTX TITAN-Z, by developing drivers that make the card convincingly faster than AMD's $1,499 offering.
