Comment 86 for bug 1768976

Yeap it helps and it is quite clear.
Still another remark. Sorry for going on with the digression here.
If there is a more proper channel we can move there.

In my old laptop when I load it with a single thread application I get

  TURBO ENABLED on 2 Cores, Hyper Threading ON
  Max Frequency without considering Turbo 1894.72 MHz (99.72 x [19])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 27x/25x/25x/25x
  Real Current Frequency 2663.14 MHz [99.72 x 26.71] (Max of below)
      Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 % C7 % Temp VCore
      Core 1 [0]: 2663.14 (26.71x) 99.3 0 0 0 0 58 0.9207
      Core 2 [2]: 2492.89 (25.00x) 4.8 5.78 1 1 85.6 55 0.9207

Now the remarkable difference is that the second core spends 86% of the time in C7 state.
On the other hand in the new laptop all cores stay in C1 state most of the time.
Same happens without load (see previous post for data on new laptop).

  TURBO ENABLED on 2 Cores, Hyper Threading ON
  Max Frequency without considering Turbo 1894.72 MHz (99.72 x [19])
  Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 27x/25x/25x/25x
  Real Current Frequency 1111.72 MHz [99.72 x 11.15] (Max of below)
      Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 % C7 % Temp VCore
      Core 1 [0]: 1019.47 (10.22x) 11.9 9.92 1 0 82.3 46 0.7955
      Core 2 [2]: 1111.72 (11.15x) 12 16.1 1 0 75.5 50 0.7955

In both cases the driver is the intel_pstate and n boh case I'm monitoring with i7z, sudo and 1 sec freq
Old processor is Intel Core i5-3337U
New processor is Intel Core i7-8750H
