The site speculates NVIDIA could launch Founders Edition reference cards as early as July, while custom-design cards from AIBs could hit the market in early September. The rumors indicate the new GeForce cards will offer higher performance at similar power consumption versus the direct predecessor model. Wallosek says he received even more information, and that's he's working to verify the specifications of these cards.
On a related note, TweakTown's Anthony Garreffa also picked up some GeForce rumors at Computex. He heard the next-gen card will offer faster performance than the GTX 1080 Ti, will cost more money than the GTX 1080 Ti, and might not be called GTX 1180. The site speculates the "GTX 1180 8GB GDDR6" could cost $999, while a 16GB variant may go for as much as $1,499. Take it with a grain of salt though, TweakTown has posted less-than-reliable rumors before.
