Turing remains the most likely architectural name for NVIDIA's next-generation of GPUs.

I have received confirmation that NVIDIA GeForce Add-in-Board partners will be getting shipments of NVIDIA’s next-generation graphics cards based on the Turing architecture sometime in Early August (nomenclature is not confirmed at this point, but GeForce GTX 1180 seems like a good bet). This follows a couple of third-party sources that have already indicated a launch in late Q3 2018 but marks the first time we have received independent verification of any progress in NV’s roadmap.
