It is fair to say that Vega has not lived up to the hype, not yet anyway. The Radeon RX Vega 64 is roughly on par with a GeForce GTX 1080, a card Nvidia released more than a year ago, and that might one reason why Nvidia is holding off until next year to bring Volta to consumers. In the meantime, if Nvidia really want to take the wind out of AMD's sails, it could inject a GeForce GTX 1070 Ti into its product lineup. A blurry photo making the rounds suggest that's a real possibility.

The photo first appeared on a web forum in China. It lists out a set of systems specs highlighted by an Asus GeForce GTX 1070 Ti Strix O8G graphics card. No such card exists officially, of course, though if it's indeed real then it would seem a launch is imminent.
