Do the new AMD Epyc and the new AMD Vega GPUs have transparent access to the same memory since both use "infinity fabric"?
If so it would seem to be a really interesting combination for chess.
There have been a few GPU/CPU combos that could do that lately, but they were under-powered development boards.
Question for you GPU gurus...

Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

No.
..and its still crossfire if you want to run multiple Vega GPU's together.

Re: Question for you GPU gurus...
Maybe the new Franken-Chip from Intel with integrated AMD Vega GPU offers what you are looking for......it looks like the integrated HMB2 is accessible by GPU and CPU:

I am not sure about AMD GPUs, but here is a pretty good talk from the Nvidia side: https://www.youtube.com/watch?v=86seb-iZCnI

Re: Question for you GPU gurus...
The power 8 processor with pascal GPUs replaces the PCI express with nvlink which is very good for memory-bound applications.
I think for chess, which is a compute-bound application, even a slow PCI connection to the CPU is Ok since we don't plan to do computation on the CPU anyway.
I believe finding the right parallel search algorithm is the main reason why chess has not performed well on the GPU.

Re: Question for you GPU gurus...Intel CPU AMD GPU combo
Here some more info about the Intel CPU AMD GPU combo:
http://www.fudzilla.com/news/processors ... m-graphics
The GPU is connected via PCIe 8x, has 4 GB of HBM memory and 20 to 24 compute units.
