    I never heard any rumours about Atari wanting to use duff XB1 chips or there being a 6C configuration. As far as I can see they are designing the...

    I think that the Atari box designers need to dump the old Bristol Ridge based design ASAP. Yeah, that $40 saved will let you get a low-end 120GB...

    I found Linux perf/$ in one of the Phoronix articles. It didn't look good, but then again, it's the only option at this level. Additionally the...

    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...
