HiSilicon Kirin 935 vs Qualcomm Snapdragon 616 MSM8939v2 vs JLQ JR510

HiSilicon Kirin 935

The HiSilicon Kirin 935 is an ARM-based octa-core SoC (system-on-a-chip) for smartphones and tablets. It was launched in the first half of 2015. It integrates two quad-core clusters of Cortex-A53 cores (big.LITTLE). The performance cluster clocks at up to 2.2 GHz, the power saving cluster at up to 1.5 GHz. Furthermore, the SoC integrates a ARM Mali-T628 MP4 graphics card and LTE Cat. 6 modem. The SoC is manufactured in 28nm and thanks to the small Cortex-A53 cores also suited for smaller smartphones.

Qualcomm Snapdragon 616 MSM8939v2

The Qualcomm Snapdragon 616 MSM8939v2 is a mid-range ARMv8-based SoC largely for Android tablets and smartphones. Announced in February 2014, the S616 is one of the first 64-bit capable SoCs from Qualcomm. In addition to 8 Cortex-A53 CPU cores at up to 1.7 GHz (power saving cluster max. 1.2 GHz), the SoC integrates an Adreno 405 GPU with a 2x 32-bit memory controller (LPDDR3-1600, 12.8 GB/s) and supports Wi-Fi (802.11ac), Bluetooth 4.0, UMTS, and LTE.

CPU

The Cortex-A53 is the successor to the very popular Cortex-A7 design. In addition to the new 64-bit capable ARMv8 ISA, the cores offer a variety of other improvements such as better branch prediction. This leads to a significantly higher performance per clock, which is even above the older Cortex-A9.

The eight cores of the Snapdragon 616 are divided into two quad-core clusters, each optimized for a different operating point. While one cluster can clock up to 1.7 GHz to handle more demanding applications, the other cluster is limited to a maximum of 1.2 GHz for energy-saving purposes. All eight cores can be active at the same time, although most applications aren't parallelized to support 8 cores efficiently.

Overall, the Snapdragon 615 offers a performance similar to that of the older Snapdragon 600 (Krait architecture).

GPU

Another new feature is the integrated graphics unit named Adreno 405 (550 MHz most likely). The Adreno 400 series has been substantially redesigned and supports DirectX 11.2 (FL 11_1) including hardware tessellation, OpenGL ES 3.1, and OpenCL 1.2. Furthermore, the performance has been significantly improved, which is now similar to the Adreno 320 and PowerVR G6200.

Features

The Snapdragon 616 offers numerous wireless technologies such as Bluetooth 4.0 and WLAN 802.11a/b/g/n/ac as well as a Multi-SIM cellular modem supporting LTE cat. 4 (up to 150 Mbps), WCDMA, CDMA, EV-DO, TD-SCDMA and GSM/EDGE.

The SoC can encode and decode 1080p videos using dedicated hardware and stream content to displays with up to 2560 x 2048 pixels. A large number of video codecs including H.265 (playback only) will be supported. The camera ISP can handle sensors with up to 21 MP.

Power Consumption

The Snapdragon 616 is manufactured by TSMC in a 28 nm LP process. According to the specifications, we expect a medium or medium-high power consumption for use in medium-sized or larger smartphones and tablets.

JLQ JR510

The JLQ JR510 is a lower mainstream SoC for (Android-based) smartphones and tablets by JLQ, a joint venture with Qualcomm and several Chinese companies.

The JLQ JR510 integrates eight ARM Cortex-A55 cores (similar to the Snapdragon 439) in two Clusters. 4 higher-clocked cores with up to 2 GHz and four power saving cores with up to 1.5 GHz.

The integrated graphics card is not an Adreno, but a ARM Mali G52MP1 (single cluster). Displays can be with resolutions up to 1080p/60Hz, for 720p 90 Hz is possible.

The JR510 also includes an AI accelerator with a theoretical performance of up to 1.23 TOPS. For connectivity, the SoC supports 4G (Cat4 / 7), Wi-Fi 5 (802.11ac), Bluetooth 5.0, FM and GNSS.
