HiSilicon Kirin 925

The HiSilicon Kirin 925 is an ARM-based octa-core SoC (system-on-a-chip) for smartphones and tablets. It was launched in Q3/2014 alongside the Huawei Ascend Mate 7 and features four Cortex-A15 cores clocked at up to 1.8 GHz. Furthermore, there are four additional Cortex-A7 cores at up to 1.3 GHz, an ARM Mali-T628 MP6 GPU and a 2x 32 bit LPDDR3 memory controller. The integrated LTE Cat. 6 modem provides download speeds of up to 300 Mbps.

Processor 

Compared to the commonly used Cortex-A9 and Cortex-A7 architecture, the A15 cores offer an at least 50 percent higher performance per clock, which makes the Kirin 925 one of the high-end ARM SoCs of 2014. On average, the CPU performance is roughly on par with the Qualcomm Snapdragon 800 or Samsung Exynos 5420

In addition, HiSilicon has integrated four Cortex-A7 cores clocked up to 1.3 GHz. Depending on the system load, the SoC will automatically switch between the powerful A15 cores and the more efficient A7 cores to improve power consumption and battery life in a concept ARM calls "big.LITTLE". If necessary, all eight cores can be used simultaneously, so that the chip can be described as a "true" octa-core SoC.

Graphics

Similar to the Samsung Exynos 5420, the Kirin 925 integrates a Mali-T628 MP6 GPU, which offers six shader clusters (~120 GFLOPS at 600 MHz, clock speed not confirmed). The Mali-T628 supports OpenGL ES 3.0, OpenCL 1.1 and DirectX 11 and offers a remarkable performance that is just sligthly behind the Adreno 330 (Snapdragon 800) or a PowerVR G6430 (Apple A7). Thus, the GPU can run even the most demanding Android games at high resolutions (up to 2560 x 1600 pixels) and detail settings.

Power Consumption

The Kirin 925 is manufactured in a 28nm process (TSMC HPM) and should have a power consumption similar to other high-end SoCs, e.g. the Exynos 5420. Therefore, the chip is suited for medium-sized (or bigger) smartphones as well as tablets.
