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

  • HP Mini with an i5 8th gen + 16GB of ram + 256GB NVME = 35W
  • RPi 5 = 27W

  Do you really think that will make a difference. For what’s worth how much do you pay to have a 35W device running all year? In my case I’m paying a crazy 0,157€/kW… Amounts to 35/100024365*0.157 = 48.14€/year considering a full load that the machine never has.

    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)
      • ark.intel.com/…/intel-core-i5-8500t-processor-9m-…

      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!
