I'd be concerned about power usage and thermal dissipation, apart from that the Ryzen & co procs look awesome.

  Zen has shown excellent efficiency figures for both the CPU itself and entire systems. That does not necessarily translate to good mobile systems, but is a good sign.

    I think the implied question was more about system software compatibility. Power management tooling is often vendor specific.

  This might sound naive, but shouldn't this be implemented within ACPI/APM? Or does pretty much every CPU family need special code for that anyway?

  Why would you be concerned about power usage and thermal dissipation? Are you concerned the power saving features don't work as good as they could with Linux (like with Skylake? at first)? Otherwise the reviews of the AMD Ryzen CPUs put AMDs 8 core parts around Intels high end 4 core parts [0][1][2][3][4][5][6][7] in terms of power consumptions, which is promising looking at the announced 4 core mobile APUs with Vega graphics. Also nice for thermal dissipation: AMD uses solder for the heatspreader, which helps with thermal dissipation. My only concern would be the idle power consumption since the PCs are idle most of the time, which seems to be ~10 watt higher than Skylake/Kaby Lake due to more power hungry mainboards. But maybe that can be fixed in Notebooks? [0] especially the R7 1700 which seems to run at a sweet spot with 3 ghz base clock.

Or not telling, but absolutely massive. Zeppelin can reach absolutely monstrous and unseen levels of efficiency, as long as it operates within its ideal frequency range.

    It's generally the case that clever software optimisations hit intel's platform first due to it's spread. Here's hoping AMD gathers interest in providing platform specific optimisations
    • tutanchamun 9y ago
      Yes, that's true. In fact I think the software side is what's holding back AMD the most (together with OEM's producing Notebooks which are subpar compared to Notebooks with Intel CPU - but maybe that is different in other regions).

        Basically, let's hope the fintech guys take a liking to it, right? ;)
