Cuối cùng là Snapdragon 425, sản phẩm dành cho những mẫu điện thoại tầm trung cận thấp. Nó sử dụng 4 nhân Cortex-A53 xung nhịp 1,4GHz, sản xuất trên dây chuyền 28nm, GPU Adreno 308, hỗ trợ màn hình 1280 x 800 @ 60fps, cho phép quay phim Full-HD, camera tối đa 16MP. Và mặc dù nhắm đến những thiết bị giá thấp nhưng Snapdragon 425 vẫn có modem 4G LTE Cat 4.
Cũng trong dịp này, Qualcomm giới thiệu modem 4G mã X16 mới. Bộ thu nhận sóng này có khả năng đạt tốc độ download lên tới 1Gbps [1000Mbps], hơn hẳn so với tốc độ 600Mbps trong modem X12 dùng với Snapdragon 820. Mặc dù vậy, hiện tại chưa có mạng di động nào đã triển khai chạm đến tốc độ 1Gbps cả. X16
được sản xuất trên dây chuyền 14nm nên sẽ tiêu hao ít điện hơn so với X12 [20nm]. Phải đến năm 2017 thì X16 mới bắt đầu có mặt trên các thiết bị thương mại.
Một điểm thú vị đó là X16 hỗ trợ LTE-Unlicensed [LTE-U], một loại mạng LTE tầm ngắn chạy trên băng tần 5GHz giống Wi-Fi n và ac. LTE-U giúp các nhà mạng mở rộng tầm phủ sóng của mình, đặc biệt là trong nhà, mà
không cần người dùng phải chuyển tiếp qua mạng Wi-Fi như các giải pháp hiện nay. Và nếu bạn chưa biết thì sóng phát ở băng tần 5GHz
A 32-bit operating system can only support up to 4GB of RAM. 64-bit allows more than 4GB, giving increased performance. It also allows you to run 64-bit apps.
With integrated graphics you don’t need to buy a separate graphics card.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
The clock speed of the graphics processing unit [GPU].
The fifth-generation wireless technology delivers higher speeds and lower latency than the previous, fourth-generation tech.

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
DirectX is used in video games, with newer versions supporting better graphics and features. The latest version is DirectX 12 Ultimate, which includes support for ray tracing, mesh shaders, and variable rate shading [VRS].
OpenGL ES is used for games on mobile devices such as smartphones. Newer versions support better graphics.
Some apps use OpenCL to apply the power of the graphics processing unit [GPU] for non-graphical computing. Newer versions introduce more functionality and better performance.
Performance
The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores [processing units]. It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores.
More threads result in faster performance and better multitasking.
Using big.LITTLE technology, a chip can switch between two sets of processor cores to maximize performance and battery life. For example, when playing a game the more powerful cores will be used to increase performance, whereas checking email will use the less powerful cores to maximize battery life.
Heterogeneous Multi-Processing [HMP] is a more advanced version of big.LITTLE technology. In this setup, a processor can utilize all cores at the same time, or just a single core for low-intensity tasks. This can provide powerful performance or increased battery life respectively.
