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).
