Qualcomm announces Snapdragon 675, a mid-sized smartphone SoC with some advanced features. Most notably, the new Kryo 460 architecture is built on ARM Cortex-A76 core, which is designed for mainstream devices and has not yet entered Qualcomm chip. (The first major SoC with the A76 is Huawei's Kirin 980.)
The Snapdragon 675 has two core performance-focused and 2.0GHz, six 1.78GHz cores designed for power efficiency. For comparison, Snapdragon 845 is now much faster because it uses four 2.8GHz performance cores based on Cortex-A75. The 845 is also made of 675 11nm to 10nm processes. However, according to Anandtech it is rare for Qualcomm to release a new CPU design for mid-range products. Especially given the fact that the Snapdragon 710 performs at a superficially higher level.
The Snapdragon 675 seems to have been designed for reality aside from its core features and is no longer the exclusive preservation of the mainstream mobile phone. While there are game enhancements for certain titles similar to Huawei GPU Turbo Optimization, the new image signal processor was built with triple camera setup in mind. Qualcomm expects the Snapdragon 675 to be applied to standard telephones in the first quarter of 2019, so you do not have to be surprised if it looks like a new device. Until then, there are three cameras in the back.
