Guru3d has published the tests of this card. And the least that we can say is that the GTX 1080 Ti Lightning Z supersedes all other video cards by far.
This GPU has a frequency of 1.58 GHz, with a boost at 1.69 GHz, more than 11 Gb of memory.
On average, the card is 6.4% more efficient than the Geforce GTX 1080 Ti which was the most powerful on the market.
At Idle, the card reaches a temperature of 36°C, it is 4°C more than the Ti.
On load, it is 66°C, 18°C less than the Ti. Which is exceptional!
At Idle, the noise is 30 DBa, compared to the 35 DBa for the Ti.
On load, it is 39 DBa, against 41 DBa for the Ti.
The spike of consumption was reached at 339 Watts. While we have 279 Watts for the GTX 1080 Ti. 479 Watts for the GTX Titan-Z.
It’s very high. But it is quite expected. It will require a power supply of 600-650 Watts to support it. For overclocking, it will be necessary to take a power supply of 800 Watts.
When overclocked, the card gains 5.3% of additional performance. With a heart then clocked at 1.65 GHz, a boost at 2.05 GHz, a memory at 12 GHz.
It is expected to be available in July 2017 at a price of $1200.
