NVIDIA's official specifications and performance numbers for their flagship GeForce GTX Titan Z have been unveiled by Videocardz. In addition to the details, NVIDIA will also possibly be moving away from the original release plans for the card and reschedule the launch for 8th May. 
NVIDIA GeForce GTX Titan Z Specifications and Performance Unveiled
We already reported several detailed specifications of the GeForce GTX Titan Z but we'll do a round-up. Built with the same heart and DNA of NVIDIA’s GeForce Titan and Titan Black Edition, the GeForce GTX Titan Z is an engineering marvel with two chips under its hood that pack 7.1 billion transistors each. The GeForce GTX Titan Z will replace the GeForce GTX 690 boasting dual-GK110 cores compared to dual-GK104 cores on its predecessor. The GeForce GTX Titan Z will feature two GK110 cores with 5760 Cuda Cores, 448 TMUs and 96 ROPs.
The card features a 384-bit x 2 bus which will run across a massive 12 GB VRAM. This is an impressive feature giving developers and games an unprecedented amount of VRAM for use. The memory is clocked at 7 GHz effective clock speed. The core clock speeds are maintained at 705 MHz base and 876 MHz boost clock and the card features a maximum single precision performance of 8.1 TFlops and 2.3 TFlops of double precision which is impressive.
The design of the GeForce GTX Titan Z is beefier compared to the GeForce GTX 690. The design is similar but the card takes up three slots to provide optimal thermals with the Dual GK110 cores in action. The card will feature dual black colored Vapor chambers placed on top of each GK110 core while a large cooler fan will push air from the internal assembly, cooling the components and letting the heat out of the front exhaust. The display outputs include Dual-DVI, HDMI and a Display Port. The card has a single SLI gold finger to enable two of these cards to function as multiple GPUs. The card is fed through dual 8-Pin connectors which represent a TDP of 375W. The card has a beefy 12 Phase PWM supply and with a 450W heatsink under its hood, the GeForce GTX Titan Z will actually be able to sustain overclocking on air around the 1 GHz mark.
The GeForce GTX Titan Z will end up with a MSRP of $2999 US which is twice to what AMD is asking for their flag ship Radeon R9 295X2. It remains to be seen whether the GeForce GTX Titan Z will be able to hold with the beast that is Vesuvius itself. The AMD Radeon R9 295X2 also comes with a hybrid cooler (Project Hydra) which provides better cooling then cards running on air cooling but the final products can only be compared once the reviews hit the web. It will be seen how well does NVIDIA’s GeForce GTX Titan Z keeps up in scaling, thermals and power consumption if it has to be seen a worthy successor to the GeForce GTX 690 and a worthy competitor to the AMD Radeon R9 295X2.
NVIDIA GeForce GTX Titan Z Performance Slides:
From the slides posted by Galaxy Tech, it is shown that the card will be able to handle to handle 40 FPS and above in several gaming titles in 4K resolution. This remains to be seen whether the same will remain true once official reviews hit next month. The Radeon R9 295X2 has been out for a few weeks and has dominated the performance ranks with its dual Hawaii cores and while GK110 core based single chip cards have had a slight edge on the AMD chips (R9 290X vs Titan Black / GTX 780 Ti) purely in performance benchmarks, the lower clocked nature of Nvidia GeForce GTX Titan Z will not be a good decision. The only thing that keeps the bar on NVIDIA card high is that it has lower power, runs quieter at 36dB and has a maximum load temperature of 83C. Other than that you have to wait for more precise performance details till next month.
