Okay so that's *way* worse. 

Everything's limited and locked to 2.2GHz. And yes, it's actually running at
2.2GHz, it's not misreporting. My Geekbench score was less than a third of
what it should be

cat /proc/cpuinfo | grep MHz
cpu MHz               : 2200.000
cpu MHz               : 2200.088
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2199.982
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000
cpu MHz               : 2200.000

This actually doesn't mean that the CPUs are running at the given frequency.

 cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
2199680
2199981
2195932
2199979
2195634
2198726
2199437
2195587
2197662
2198924
2198856
2195535
2196402
2199234
2199880
2195064

And so this.

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 2.20 GHz - 6.00 GHz
  available frequency steps:  3.80 GHz, 2.80 GHz, 2.20 GHz
  available cpufreq governors: performance schedutil
  current policy: frequency should be within 2.20 GHz and 2.20 GHz.
                  The governor "schedutil" may decide which speed to use
                  within this range.
  current CPU frequency: 2.20 GHz (asserted by call to hardware)
  boost state support:
    Supported: yes
    Active: no
    Boost States: 0
    Total States: 3
    Pstate-P0:  1000MHz
    Pstate-P1:  700MHz
    Pstate-P2:  500MHz


Both schedutil and performance governors had no effect. 

But I do see in that cpupower output that it says the hardware limits happen
to be 2.20GHz to 6.0GHz.

That's as expected.
