    I think they're using 8GB now, so hopefully 2x4GB (or the equivalent soldered onto the motherboard).

    I guess it depends on what AMD want to use their 7nm wafers to make. Maybe priorities have changed given Intel's 10nm delay - less need for 7nm Rome...

    JeeBee replied to a thread AMD Picasso / Raven Ridge 2 in CPUs
    Yield is closely linked to the die size - 80% for a 200mm^2 die is okay, but for a 50mm^2 die it's not great. Defect density is a better metric.

    I find that unlikely, unless perhaps you are doing yield / node-specific-die-size (~225mm^2 16nm to ~100mm^2 7nm). Given the high number of extra...
