Qualcomm Snapdragon 430 (MSM8937) vs Qualcomm Snapdragon 617 MSM8952 vs Qualcomm Snapdragon 425 (MSM8917)
Qualcomm Snapdragon 430 (MSM8937)► remove
The Qualcomm Snapdragon 430 (SD430) is a lower mainstream SoC for (Android based) smartphones and tablets. Contrary to the Snapdragon 630, it is still manufactured in a 28-nm process and also consists of an octa-core CPU part with ARM Cortex-A53 cores. However, they are only clocked at up to 1.4 GHz. The integrated X6 LTE modem supports Cat. 4 with maximum transfer rates of 150 Mbps (downstream) and 75 Mbps (upstream). The SoC also includes an Adreno 505 GPU with support for Vulkan and OpenGL ES 3.1. WiFi 802.11ac and Bluetooth 4.1 are supported as well. The memory controller supports LPDDR3 clocked at 800 MHz (so probably dual-channel DDRL-1600).
Qualcomm Snapdragon 617 MSM8952► remove
The Qualcomm Snapdragon 617 MSM8952 is a mid-range ARMv8-based SoC largely for Android tablets and smartphones announced in September 2015. In addition to 8 Cortex-A53 CPU cores at up to 1.5 / 1.2 (performance and power saving cluster) GHz, the SoC integrates an Adreno 405 GPU with a LPDDR3-1866 memory controller and supports Wi-Fi (802.11ac), Bluetooth 4.0, UMTS, and LTE. Compared to the older Snapdragon 615, the clock speeds are a bit lower (hits 1.7 GHz max).
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 617 are divided into two quad-core clusters, each optimized for a different operating point. While one cluster can clock up to 1.5 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 617 offers a performance similar to that of the older Snapdragon 600 (Krait architecture).
Another new feature is the integrated graphics unit named Adreno 405 (most likely around 550 MHz). 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.
The Snapdragon 617 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.
The Snapdragon 617 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.
Qualcomm Snapdragon 425 (MSM8917)► remove
The Qualcomm Snapdragon 425 (8917) is an ARM-based entry level SoC for tablets and smartphones (mostly Android based). It was announced in February 2016 and integrates four 64-Bit Cortex-A53 CPU cores (quad-core) that clock with up to 1.4 GHz. Furthermore, there is a Adreno 308 graphics card, a LPDDR3 memory controller (max. 667 MHz) and wireless radios for WiFi and 4G/LTE included in the chip.
The Cortex-A53 is the successor of the entry level Cortex-A7 CPU cores. The A53 is now capable of 64 Bit (ARMv8-ISA) and adressing more than 4 GB RAM. According to ARM the performance per MHz is a lot better and even surpasses a Cortex-A9 core.
The integrated Adreno 308 ist the integrated graphics card that supports OpenGL ES 3.0.
The integrated wireless radios support WiFi 802.11ac Wave 2, Bluetooth 4.1, GPS/GLONASS/Baidou, 2G, 3G and 4G (LTE Cat.4) standards. Futhermore, the SoC is able to decode 1080p videos in H.265 (encode only in H.264) and cameras with up to 13 MP.
The power consumption of the chip is ranging in the lower range, and therefore it is also suited for smaller smartphones. It is manufactured in 28 nm LP at TSMC.
