So we're only left with RISCV? Sparc seams a dead end, and power too.

  IBM is actively investing in POWER though

    Would be nice if they brought that back into the laptop realm.

      There is a project to make a power pc laptop https://www.powerpc-notebook.org/en/ https://www.powerpc-notebook.org/en/ Though it does not use a IBM CPU.

        They claim to be using a NXP T2080 CPU as the core of their laptop. This is doomed to failure. The T2080 is a high-speed communications processor. It is not designed for energy efficiency. It can draw up to 20W at full power, and does not support the sorts of power-saving features that would be required for a mobile part. The datasheet doesn't even specify the processor's idle power consumption! Some of the tables can be read to imply that it might be able to idle down to roughly 7W, but that's still completely unsuitable for a laptop.

        Are there other Power processors that might be better suited for a laptop?
        duskwuff 6y ago
        Somewhat not by much. NXP has a couple of other QorIQ parts which might fit a laptop application a little better; for instance, the T1040 series (4 cores, 1.5 GHz, 7W TDP) seems like a better fit. IBM's POWER parts are aimed squarely at supercomputing and are completely unsuitable for this use case. But, quite frankly, none of these parts are really intended for mobile use. There hasn't been any real interest in mobile Power hardware since Apple got out of the business nearly 15 years ago -- ARM cores have utterly dominated that market.

  Power ISA isn't dead. Besides IBM's server offerings, you can buy workstations with a POWER9 retail right now. POWER10 is in the works and it's a royalty-free ISA. That's in addition to all the little embedded cores that are still around.
