Atom and Core/Xeon don't share microcode? e.g. vulnerabilities in one would never work on the other?

- adrian_b 4y agoNo, the microinstruction formats are very different, so also the microprograms must be different. Even the newer Atom cores, e.g. the Tremont cores from Jasper Lake/Elkhart Lake/Snow Ridge/Parker Ridge/Lakefield have a different microinstruction format than that which has been published now. For every generation of Intel CPUs, reverse-engineering the microcode requires all the work to be done again, what has been discovered for another generation cannot help much.
