The 5700 XT has 2560 Shader Processors, the 14nm Vega 64 has SP 4096 SPs, the 7nm Radeon VII oddly has slightly less at 3840 SPs and some expensive HBM2 memory.
Does it seem likely that the process shrink to 7nm+ combined with RDNA redesign (v2) will allow high end navi to include upto 4096 SPs (plus more compute units), presumably with a lower TDP than Vega 64 and corresponding lower GPU core temps?
Also the Vega 64 has a chip die size of 495 mm², which clearly shows it's possible for AMD to design chips upto this size if needed, compare this to current gen. Navi with die of just 251 mm².
If all this is true, it suggests perf. improvement of between 33.3-40 % over the 5700 XT, resulting in similar performance to the RTX 2080 Super for high end Navi.
Speculation - HBM memory will be reserved for exclusive super expensive GPUs, like a Radeon VIII, because AMD can increase memory bandwidth with memory bus size increases instead, Vega also has a larger memory bus size than current Navi.
Unrelated fact - Vega was released in August 2017, maybe a clue to the release of high end Navi?
