The silicon rumour mill has spun into overdrive regarding Nvidia's upcoming RTX 2000-series GPUs.
We already know the premium line of upcoming cards, based on the Turing architecture, will use derivations of the TU1xx codename, but until now no further substantive details have emerged.
Chief protagonists of the rumour mill, VideoCardz, has apparently been able to 'confirm' that the two best gaming cards will be known as RTX 2080 Ti and RTX 2080. That makes sense going by Nvidia's recent naming convention.
What's new is the shader-core, memory type and speed specifications, so thanks to those fellas over there, we present what is assumed to be fact.

Specifications, as rumoured by VideoCardz
Compared to GeForce GTX 1080 Ti, the new RTX champ is supposed to have over 20 per cent more shaders - plus, one would assume, higher clockspeeds due to the 12nm process - plus heaps more memory bandwidth due to the use of GDDR6 running at a blistering 14Gbps.
Realistically, if VideoCardz' information is correct, even without the efficiency benefits of the Turing architecture, we'd most likely be looking at 30 per cent more shading power and almost the same uptick in memory bandwidth. That ought to lead to some impressive gains when gaming at 4K.
The RTX 2080, meanwhile, cuts down the shader-count to 2,944 but keeps memory bandwidth the same. One would expect it to run the present GTX 1080 Ti reasonably close, going by pure numbers alone.
There remain lots of unknowns, most of which will be detailed during Gamescom next week, but if these high-level specs are true, RTX 2080 (Ti) offer solid gaming promise.
What do you guys think? Do the numbers stack up?
