Back in early March VRCircle reported the Titan X is driving the new VR Oculus Demo experience called Thief in the Shadows, a joint venture from Epic, Oculus and Weta Digital.
Nvidia have now released full details of their new Titan X video card which is now the single fastest single GPU video card around.

Onto the technical details of the Titan X. 3072 CUDA cores, which are spread out over 24 SMMs. Beyond the 128 CUDA cores that each SMM carries, they also carry eight TMUs, making for a total TMU count of 192. It also has 96 ROPs on board.
The base frequency of the GPU is 1000 MHz with a maximum boost up to 1075 MHz so long as the thermals are within range. Titan X contains 
12 GB of GDDR5 memory running at 7.0 GHz, providing a memory bandwidth of 336 GB/s.
Nvidia claims the Titan X can perform 7 teraflops (SP) and 0.2 teraflops (DP).

The GPU is based on the Maxwell architecture but it is however still using the 28 nm lithographic process. The GPU has eight billion transistors so it is one of the biggest around sucking up 250 W of power.

This is the good news, the card is powerful. How much will this power cost you? Titan X will run you $999. Which is roughly double the price of a GTX 980 making this card viable for the hardcore power user only. For those of us playing the waiting game for VR hardware such as HTC Vive and Oculus Rift CV1.
I would recommend waiting.

Is the GTX Titan X worth the price premium?
