I think TechPowerUp most likely based these spectimates on the Quadro RTX specs listed on the Nvidia website, as its usual for Quadro cards to match the High/mid/low end spec's of its desktop equivalent, with slight changes to memory and clocks.
I think they are fairly good guesstimates, other than the Titan RTX, which I think will have 4,608 Cuda cores, 576 Tensor cores, and 12 or16Gb G6 memory.
I cant help thinking that Turing, is basically a slightly modded Volta. 512 Cuda cores missing, 64 tensor cores gone, yet there are new RT cores, and Nvidia not listing the amount used?... I think these RT cores will turn out to be optimised tensor cores for raytracing or some slight architectural restructuring involving those 512+64 missing cores..., nevertheless I am sure whatever they have done, its very clever.
From a business point, it makes no sense for Nvidia to invest their biggest R&D budget to date in Volta, and then not reap the benefits gaining back their investment with interest from the consumer market, only leaving Volta to the DCC, HPC, Enterprise, Deep learning crowds... So I think when the hood is lifted, Turing will end up being a revamp of the existing Volta architecture, but just guessing here like everyone else...
I watched that Nvidia teaser a few days back. Another site had a break down of all the Easter Eggs hidden in the nicknames and chat messages.

Just 4 days to go...
How disappointed are we all going to be when they reveal...
Wait for it....
