Samsung Exynos 7884B vs Qualcomm Snapdragon 610 MSM8936 vs Qualcomm Snapdragon 630

Samsung Exynos 7884B

The Samsung Exynos 7884B (also called Exynos 7 Series) is a upper mid-range system-on-a-chip (SoC) for smartphones and tablets. It integrates two big ARM Cortex-A73 cores clocked at up to 1.56 GHz. Furthermore, there are six power efficient Cortex-A53 cores at up to 1.35 GHz, an ARM Mali-G71 MP2 GPU and a LPDDR4x memory controller. Compared to the faster Exynos 7885, the CPU cores of the 7884B are clocked clearly lower. Furthermore, the integrated LTE modem is also slower (150 / 50 Mbit download / upload). 802.11ac WiFi, Bluetooth 5.0 and FM Radio are also in the chip. It is manufactured in 14nm FinFET at Samsung and therefore a rather power efficient SoC.

Qualcomm Snapdragon 610 MSM8936

The Qualcomm Snapdragon 610 MSM8936 is a mid-range ARMv8-based SoC largely for Android tablets and smartphones. Announced in February 2014, the S610 is one of the first 64-bit capable SoCs from Qualcomm. In addition to 4 Cortex-A53 CPU cores at up to 1.7 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 four cores of the Snapdragon 610 are clocked at up to 1.7 GHz, offering 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). 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 610 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 1600 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 610 is manufactured by TSMC in a 28 nm LP process. According to the specifications, we expect a medium power consumption for use in medium-sized smartphones and tablets.

Qualcomm Snapdragon 630

The Qualcomm Snapdragon 630 (SDM630) is a mid-range octa-core SoC with eight ARM Cortex-A53 CPU cores at up to 2.2 GHz, an Adreno 508 GPU, a LPDDR4-2666 memory controller (1333 MHz) and a X12 LTE (Cat 12/13, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 5.0. It is manufactured in 14nm FinFet. The processor performance should similar to the older Snapdragon 626 which offers similar clock speeds. Compared to the 626, the 630 however supports faster memory and offers faster LTE, Wifi and Bluetooth standards.
