by the way, the Coffee lake chip still has it's working integrated graphics. This Vega only kicks in when in games.
So it really is some kind of hack job. Hopefully Ryzen Mobile will eventually have some closer integration if they come out with such a solution. If they could get Hybrid Crossfire working properly....
Or of that nice stack of HBM2 can be directly accessed by the processor as well.
Agree, AMD is not strong in mobile segment.
Probably that is one reason why they work with Intel for that.
I own AMD notebooks with Dual Graphics/Hybrid Crossfire.
However Dual Graphics/Hybrid Crossfire is not a prefect tech,
firstly mainly due to lack of proper drivers from OEM.
You can use driver from AMD but on some notebook the dual
graphic may not work properly.
Whether will that change with Ryzen mobile, no one knows.
