Huawei's Kirin 930 flagship CPU uses enhanced Cortex A53e cores pushed to 2GHz clock speed

Predictably, some questioning ensued, as the A53 cores are low powered and play second fiddle to the hotter A57 cores in the typical octa-core configuration. However, Huawei chimed in with an interesting explanation. Apparently, the Kirin 930 is based on four regular Cortex A53 cores and four enhanced Cortex A53e cores. The latter appears to be a Huawei creation, and are remarkably different to the traditional Cortex A57 and Cortex A53 cores. For starters, stock A53 cores traditionally run at 1.2GHz, which doesn't cut it for flagship performance. So Huawei pushed them as hot as 2Ghz, which makes them nearly as fast as Cortex A57 cores, but more power-efficient.

According to the company, A57 cores, which are about 56% faster than A53 cores, could eat up as much as 256% more electricity, which results in heat creation and reduced battery life. So Huawei made a careful compromise and ended up with slightly slower, but hopefully more power-conscious cores.
