This round its Digitimes that spreads the word that TSMC obtained major orders from Nvidia for their next-gen 7nm and 5nm GPUs, sources claim that is.

Speculation is circulating that Samsung Electronics' 5nm EUV process has attracted orders from Nvidia for its next-generation graphics processor series, but sources familiar with the matter believe TSMC will remain the major foundry partner of the chip produces says TSMC.

That's a good signal for the availability of the new GPUs really, as the production tarts then indeed Q3/Q4 2020 seems viable for new graphics cards. Considering what is and has been going on in the world, that is plausible. NVIDIA is expected to reveal a few words on their next-gen graphics architecture at the GTC 2020 online event held in about two weeks from now, Nvidia would have their chips fabricated at both Samsung and thus TSMC.
