ARM said Cortex A35 is the most power efficient processor, its power consumption is only 125mW. If adopting 28nm process technology and 1GHz frequency, its power consumption will reduce to 90mW. If keeping same power consumption and adopting 16nm or 14nm process, then its frequency can be over 2GHz.
Of course, it can also work with ARM Cortex A53, A57 or A72 to boost the performance of CPU.
Compared with Cortex A7, under same frequency and process technology, its power consumption is 10% lower, and performance is 6%-40% higher. If comparing with Cortex A53, its performance will be about 20% lower, but power consumption is 32% lower, and its size is also much smaller.
The first CPU with this ARM Cortex A35 may roll out at end of 2016.
