I wish that AMD would give their APU's a quad channel memory controller for better bandwidth. A quad core APU with 24 CU's and 16gb (4x4gb) of ram @ 3466mhz would make for a solid little machine.
A small amount of optional dedicated GDDR5 like was done with TurboCache and Sideport a number of years about might also be a cost-effective option. iGPUs more memory bandwidth and lower latency than system memory can provide alone and it might not be acceptable to add in two more memory channels.
Due to the AM4 socket on the desktop, AMD can't add more memory channels without changing the socket. If AMD adopts Gen-Z in the next few years, that has the potential to change things a lot in terms of how memory is addressed, because it can do away with the need for more memory channels to get higher bandwidth access to memory. Memory would be on the Gen-Z bus, and the CPU would just talk to the bus. This might require the new socket, or Ryzen fourth generation might be able to support it on AM4(if the motherboard is Gen-Z, then all pins for PCI Express slots and RAM could be used for the Gen-Z connection, if the motherboard is "legacy", then the CPU would use legacy mode and be limited to the 2 channels. How long it will take for Gen-Z to show up is the question.
Did AMD say if they are going to release optimized drivers for thier mobile Raven Ridge APU's? Current drivers for Ryzen 5 2500u are still stuck on 17.7 and are released from OEMs not AMD. Power management between the CPU and GPU is all wrong.
As good as this is, what I really expected AMD to produce is what they gave away to Intel or did with the Chinese: Produce an APU which doesn't compromise on the graphics, even if that precludes the 15Watt mobile space (BTW: Is there any initiative to produce mobile GDDRx or HBM?).
So put some HBMx on the die carrier and then use DDRx only for the CPU (would even work with an AM4 socket, right?) or go all GDDR5 like they did with the console and perhaps allow to combine several of these consoles into something beefier (2x, 4x) connected via IF.

Maybe take a closer look at what Mythic is trying to do and reconsider?SquarePeg - Monday, August 20, 2018 - link

Is this desktop or laptop apu? Kinda to soon for an upgrade isnt it? 2019 would make more sense..abufrejoval - Friday, August 24, 2018 - link
