Here you go: https://docs.google.com/spreadsheet/...FWN2c&hl=en_US BTW your analogy of the motorbike to the car is FLAWED. Comparing those two is symmetrical to comparing an ARM SoC to an x86 CPU. Obviously the x86 has more grunt but the ARM would win due to definite design advantages i.e. SoC I would say the analogy your looking for is more like comparing two cars one with sports tyres (lots of grip) and one that is stock (and slightly deflated). The first car needs less power to overtake the second car, but how much is the difference in tyre effeciency compared to the power (SoC) compensation?
