They can use different clock speeds per core, no? So, no make sense put the OS core to run at 2.1 Ghz equal to the games cores. So, 0.438 for 7 cores, what is 3.06W.Yes, since Arm mentioned that the Cortex-A78 on TSMC's N5 process node consumes 1 W per CPU core at 3 GHz, which is 8 W for 8 CPU cores.
Assuming that the Cortex-A77 on TSMC's N7P process node consumes ~0.877 W at 2.3 GHz (by taking the percentage difference between 2.6 GHz and 2.3 GHz since Arm confirmed the Cortex-A77 on TSMC's N7P process node consumes 1 W per CPU core at 2.6 GHz), since Arm said the Cortex-A78 on TSMC's N5 process node consumes half the amount of power that the Cortex-A77 consumes at 2.3 GHz, but at 2.1 GHz, I assume the Cortex-A78 consumes ~0.438 W per CPU core at 2.1 GHz, which is ~3.508 W for 8 CPU cores.
3W for CPU + 4W for GPU + 2W for screen and others parts is 9W for entire system on portable mode. What give 2+ hours on a 20Wh battery. Maybe CPU + GPU on a integrated SoC can consume less than 7W and the battery life can be even bigger.
