Not sure if phoronix wants to get into all that video memory stuff, but if they do, I hope they do it right, that's all.
    I agree the memory should be reported.

    But having to guess with the stats is pointless. If AMD had opened the performance counters, we could have a label next to each benchmark result saying "this benchmark was mostly memory-bound" or similar. Now the best that could be done is to determine whether the bench was CPU or GPU bound, nothing more.

    Eh, I tried to change that months back, but got a response that Jerome (IIRC it was him) wants to create a new way to report information.

    GPU-Z needs updates for every new GPU, does it not? This really points to it having some built-in database of them.

    IIRC, GPU-Z uses vendor specific interfaces to get that information.

    Do those interfaces change each generation? That could explain the per-GPU new versions too.
