Guys i just bought this device but then I realized that there is no efficiency core in the device. It has 8 cores and all of them are ARM Cortex-A725. A few of them have been underclocked to 2.1 GHz, but this does not mean that they are efficiency cores. No matter how much these cores are underclocked, they are very large and consume a lot of power. I think this is a big problem for the lifespan of the device, what do you think?
They are efficient enough to not be a problem.
