    Are there any 45w class Ryzen mobile CPUs?

    There's U-series Ryzens, but what about H-series?

    Apparently so, or at least plans for them.
    Two embedded versions of Raven Ridge are rated at 35-54W, and the other two are 12-25W, but both seem to use an FP5 socket (BGA).

    I think that on 12nm we could see only 65W desktop parts inside some gaming laptops but that is it until 7nm next year. Since every Zen die is an essentially 8c/16t I am not sure that with 45W Zen you could get sufficient boost on 1 or 2 core to compete with 45w i7 mobile parts.

    If you don't need the Vega GPU, there are also "Epyc" branded embedded parts that are rated 45w and 50w, though the single die parts seem to have only two memory channels so they are similar to Ryzen. These use a SP4 socket (BGA).

    I wonder if the teased Acer Predator Helios 500 with Ryzen 7 2700 and Vega 56 would use an SP4 or AM4 socket. (The 50w embedded chip, on the page linked above, is rated for lower clocks than the 65w desktop chip, but it might be adjustable/undervoltable/overclockable with good cooling.)
