AMD could present the AMD Navi in August 2018, possibly at SIGGRAPH 2018, the same event used this year to present the AMD RX Vega for the gaming segment.
We know that AMD next year will launch the Vega 2 or whatever you want to call them, which will not finally be in 14nm +, a revision of the current 14nm architecture, but will be developed in 12nm, predictably and as it has been leaked. Vega has been a total failure, which has brought Raja Koduri to the fridge and there he continues, until he or the company decide what to do. The interesting thing is that AMD could announce AMD Navi in the month of August 2018, just coinciding with SIGGRAPH 2018, an event used this year to present the RX Vega for gaming.
The new AMD Navi will be based on the 7nm manufacturing process, a manufacturing process that is beginning its development by GlobalFoundries. The step to 7nm is important, especially for energy efficiency, something that Vega clearly suspends, which has a very high consumption. AMD also with NAVI could bet on developing a multi GPU, something seen in Ryzen, which are based on multi CPU. It seems that they would also use Infinity Fabric, something that does not seem like a good idea, since it generates a lot of bottlenecks in the processors.
This strategy of developing several GPUs in the same package is due to the development of DIE that are easier to manufacture and are cheaper, allowing a greater amount of stock and being able to compete again in price with NVIDIA solutions. Developing simpler DIE would increase the stock manufacturing capacity, reducing costs, lowering the price of graphics and maintaining acceptable margins. For that there is still, before we will see the Vega 11, substitutes for the AMD Polaris and the Vega in 12nm, substitutes for the Vega in 14nm.

With the vega fiasco (which cannot even compete with nvidia in price), I don't expect much from NAVI, hopefully I'm wrong!
I see a problem, the performance loss will be great because of the communication between the gpus much more than in a cpu
Amd should incorporate into its architectures the sale of hbm2 memory instead of ram to increase the speed throughout the system.
