So what is 5nm or 3nm?

• aarongolliver 7y ago
  It has about the same meaning as the 5 or 3 in "core i5" or "core i3". It's all marketing.

  The process marketed as 5nm has roughly twice the density as the process marketed as 7nm and so on up and down the line; that's how they justify it.

    How can they double the density without decreasing the feature size?

      I am wildly speculating here, but maybe going 3rd dimension?

      The feature side usually does decrease every generation; it's just that the feature size for, say, a "7nm" process is not exactly 7nm.

        The power of recursive reasoning. Induction tells us that Intel's 10nm process probably wasn't 10nm features...
