Reported specifications for Nvidia's GTX 1180 have leaked from Wccftech, who is a reputable site but not always super accurate with leaks.
We have already reported that the next generation of Nvidia cards could be named GTX 1180 /1179 rather than 2080 / 2070. It is looking more like the cards will be launch sometime in the summer, possibly around July. Followed past trends, and current rumours, pricing will go up as usual and the base price will be around $699 vs the $599 of the GTX 1080 or $699 of the founder's edition.
The claimed GeForce GTX 1180 is powered by a 104 class GPU, codenamed GT104. The GPU measures around ~400mm², features 3584 CUDA cores, a 256-bit GDDR6 memory interface and 8 to 16 gigabytes of 16Gbps GDDR6 memory. The graphics card is expected to have a core clock of around ~1.6GHz and a boost clock of around ~1.8GHz. The TDP of this graphics card is unconfirmed to date but is expected to be somewhere between 170-200W.
A chart has been released of relative performance, which I think we can take with a grain of salt, but it shows a 51% improvement over the GTX 1080 and a decent improvement over the 1080Ti and Titan Xp
