3.5-4Mhz was standard for most Z80 based systems.

  Still, it didn't perform much better than a 1Mhz 6502 due to its design.

    Elite on the Spectrum ran much faster than Elite on the C64.

      Technically correct. Its ~6fps on C64 and ~8fps on Spectrum.

        Yeah, the difference definitely doesn't match the quadruple clock speed.
