    I’m seeing more like 7ghz for the bismuth stuff, still really good but nothing completely insane like 500 ghz. Do you have a source for that?

      Oh, the 500ghz is the max theoretical switching (0<>1) limit for Bismuth itself, not for any production chip any time soon, sorry about that. I saw it in either the paper or at ‘Anastasia in Tech’ on youtube. (worth following if interested in chip development).

        From what I can find, the ratio of ‘theoretical speed’ to current commercial ICs in silicon is about 1:20, so that would equate to about a 25GHz chip, all other things being equal (i.e. if that ratio isn’t some inherent feature of silicon…)
