Comment on Banana Pi BPI-M7 - More Reasons to Avoid the Raspberry Pi

  Lmao did you just compare the highest possible power consumption on a Pi with the lowest possible consumption on a desktop PC?

    Lmao, do your research before commenting stuff like that.

    • support.hp.com/ee-en/document/c06045012 (variant Intel Core i5-8500T)

    TDP 35 W Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload. Refer to Datasheet for thermal solution requirements.

    Here’s how things look on the HP model above:

      Model name:            Intel(R) Core(TM) i5-8500T CPU @ 2.10GHz
        BIOS Model name:     Intel(R) Core(TM) i5-8500T CPU @ 2.10GHz To Be Filled By O.E.M. CPU @ 2.0GHz
        BIOS CPU family:     205
        CPU family:          6
        Model:               158
        Thread(s) per core:  1
        Core(s) per socket:  6
        Socket(s):           1
        Stepping:            10
        CPU(s) scaling MHz:  23%
        CPU max MHz:         3500.0000
        CPU min MHz:         800.0000
    

    Obviously that thing wont be running at base frequency while idling. Here is one if units right now:

    analyzing CPU 0:
      driver: intel_pstate
      CPUs which run at the same hardware frequency: 0
      CPUs which need to have their frequency coordinated by software: 0
      maximum transition latency: 4294.55 ms.
      hardware limits: 800 MHz - 3.50 GHz
      available cpufreq governors: performance, powersave
      current policy: frequency should be within 800 MHz and 3.50 GHz.
                      The governor "powersave" may decide which speed to use
                      within this range.
      current CPU frequency is 800 MHz.
    

    See, it scales down to 800Mhz with a watt meter I remember it translated to idling at around 10-11W.

    I never said it was better than a Pi, I just said the difference is not worth it and you’re still ignoring the fact that i5-8500T will be able to do as much work as the Pi5 without even going over 2.1 GHz - not surpassing the 35 W TDP.

      Okay got it, so you compared the highest possible TDP on a Pi with the average/idle TDP on a desktop, and you’re acting like that’s a fair comparison. Thanks for clearing that up!

        No… I compared the highest possible TDP on a Pi with with the average TDP of a “T-CPU”, (power-optimized) and I concluded by saying a realistic idle consumption is 11W. I also added that the Intel CPU on will make more work without reaching the typical CPU than a Pi at a highest possible TDP.
