What about Atom? As I understood it Atom processors did not use speculative execution.

  That was only the case until 2013 or so. Modern Atoms are vulnerable.

    And the old Atoms were so slow that few people bothered with them.

      There were tens of millions of EeePCs sold. At one point Asus EeePCs were outselling all Macbooks.

  IIRC, the first generation Xeon Phi had cores very similar to Atoms too.

    Those cores were a bastard child of P54C[0] cores with the beginnings of (though not instruction compatible with) AVX512 + 64bit support (original Pentium had neither of these). They were not like Atom cores at all. The second generation Xeon Phi cores are pretty much based on beefed-up Airmont Atom cores. 0. https://en.wikipedia.org/wiki/P5_%28microarchitecture%29#P54C https://en.wikipedia.org/wiki/P5_%28microarchitecture%29#P54...
