Releasing CPU Snapdragon 820, Qualcomm moved to the technological process of 14 nm, starting its spread in early 2016. This technological process has been available for the chips in the middle segment Snapdragon 625, which appeared to replace Snapdragon 617. The technological process of 14 nm FinFET allows to increase the energy efficiency. Snapdragon 625 consumes 35% less compared to the Snapdragon 617 on the 28 nm process technology.
In the result, the Snapdragon 625 proved to be extremely popular, working smartphones from Xiaomi 4 Redmi Note for $150 to BlackBerry KEYone for $500. In the second half of 2017, Qualcomm introduced two updates of the line Snapdragon 600 Snapdragon models 630 and 660.
Snapdragon 630 is the successor to the Snapdragon 625, with up to 30% faster cores, support Bluetooth 5, faster LTE modem, USB 3.1 to USB interface With the image processor and the standard charging Quick Charge 4.0.
Snapdragon 660 is an even more interesting product that came to replace the Snapdragon 653. It aims to bring the performance of the flagship level devices average price category and has received a number of updates.
The processor has two cores Kryo, for the first time in this price segment, the new Adreno 512, the Snapdragon X12 LTE modem with the speed of incoming connections up to 600 Mbps and aggregation of three frequency bands, Wi-Fi, a/c with 2×2 MU-MIMO, the image processor 160 Spectra, 5 Bluetooth, Quick Charge 4.0 and USB 3.1. We are talking about improving productivity by 20% compared to the Snapdragon 653 with the new Kryo 260 cores and increase GPU performance by 30%.

, No information about which ARM core-based Kryo 260, but most likely Qualcomm used their own design, as was the case with Kryo 280 to Snapdragon 835. The kernel is divided into two clusters for maximum performance and energy efficiency. In the first case, the clock frequency reaches 2.2 GHz, 1.8 GHz in the second.
of Particular interest is Spectra 160, allowing you to create a great camera. Supported hybrid autofocus, dual rear camera with a resolution of each sensor 16 MP, dual photodiode auto focus, smooth optical zoom and electronic stabilization, video.
Smartphone Oppo R11 was the first on the Snapdragon processor 660 and allows to compare the results with models for Snapdragon 652, 835, and others.
These data show productivity growth to a level close to last year leaders. There is also a significant increase in battery life compared to smartphones on Snapdragon 650, 652, and 653.
Главная проблема в момент появления Snapdragon 660 заключалась в дефиците процессоров. Smartphone Oppo R11 продавался только в Азии, планов вывести его в другие регионы у компании не было. В последнем квартале года, который уже начался, должны появиться новые смартфоны на этом чипе. Одним из них является Moto X4.
When the deficit problem is resolved, the processor can be extremely popular among manufacturers. The speed of the CPU it is close to the flagship Snapdragon 835 and easily ahead of the budget model.
