The company has just announced a major upgrade, too, with the release of the Cortex A72. According to helpful ARM bar graphs, it promises to be up to 3.5 times faster than the A57.
The base architecture is the same as the A57, but it has been shrunk, streamlined, and optimized, with notably better branch predication, lower latency execution units, and faster L2 cache. The key in this sector is power consumption, and here the 16nm A72 addresses the weakness of its predecessor, claiming to be up to 75 percent more efficient. The interesting result of all this…
