And that's ignoring the fact that HBM is high latency - high bandwidth, which is a good compromise for GPUs, but not so good for CPUs.
    32Gigs?

    Crazy are You, not enthusiastic.

    8GB RAM and 8GB GDDR5 is max what games need. You wont find any game that would take more.

    32GB is for professionals who do HD editing of videos and photos.

    But that 8+8 assume those are sepparate. Most of that space if for textures and the like that need to be prepared by CPU (thus DDR3) and then consummed by GPU (thus GDDR5)...

    With APU both CPU and GPU can work from same copy, so 8GB of HBM2.0 would be enough for today games. Add 16GB if You have cash.

    Yes, it is an APU and has HSA.

    This is first generation HBM.

    ... enthusiast ...
    An enthusiast won't use an APU/compact pc.
    An enthusiast will use a dedicated GPU.

    And again I miss some IDLE comsumption tests indicating how much the CPU/GPU drains when it has nothing to do - which would be most of the time! Any opinions on that?

    I agree.

    Hypothetically speaking, I imagine AMD might be able to engineer an APU that's an FX-8370 processor (their current flagship, not counting the factory overclocked FX-94xx chips) plus an integrated R9-380 GPU for some new socket. But then:
    - You can't upgrade the CPU independently of the GPU, and vice versa.
    - You have a motherboard with that socket type. So if you decide that you do prefer to upgrade CPU independently of GPU or GPU independently of CPU, you need to buy a new motherboard too.
    - AMD would have to hope lots of people buy this to cover their production costs.

    It just doesn't make sense. The sweet spot for APUs is right where AMD is today - $150 and less.

    And what use would you have for a computer without RAM?

    Personally I am fine with a i5-2500k that is a older fab tech, but with solder so it can be cooled to sane temperatures without a $150 water cooler.
    You can ask Michael what he thinks about runaway electrical bills and cooling etc.
    These desktop CPU's are indicative for their respective architectures. While you are right for a single CPU desktop, most of us who have real jobs deal with large quantities of servers, clusters etc. Compute/Power efficiency is damn near everything in the equation.

    Yoo have it in glxinfo with recent mesa.

    OK. Who have some RadeonSI hw and is brave enough to run:

    Code:
    ldconfig -p | grep ll
