AMD Big Navi coming in Q4 2020 with 16GB GDDR6?

Chiphell leaker wjm47196 claims AMD will release its Big Navi video card in Q4 2020 and that this model will have 16GB video memory. The poster has a history of legit leaks, he doesn't mention the type of video memory but it's assumed Big Navi will use GDDR6.

When it comes to the development progress of the Big Navi GPU, the first validation sample was sent recently to Shanghai for driver development. While this happens, AMD engineers situated in the United States have yet to visit the manufacturing and test labs based in China to evaluate the final performance of its Big Navi GPU. This means that all previous rumors on the performance of Big Navi graphics card hold no truth at all and were simply speculation.

AMD has reportedly still not finalized the PCB design of Big Navi. The company is expected to send AIB partners its first design resources for Big Navi within the next two weeks. This implies there will be no custom-design cards at launch.

NVIDIA's Ampere desktop GPUs are expected in September so AMD will have some time to assess the competitive situation and price its cards accordingly.
