Mediatek MT6739 vs Qualcomm Snapdragon 439 vs Qualcomm Snapdragon 435

Mediatek MT6739

The MediaTek MT6739 is a 64-bit ARM-based SoC launched in 2017 primarily for small budget Android devices. The quad-core processor is based on the Cortex-A53 architecture and clocks up to 1.5 GHz. It integrates an LTE modem (Cat. 4 DL / Cat 5 UL) and a PowerVR GE8100 at 570 MHz (the predecessors used ARM Mali GPUs). Furthermore, the SoC integrates a 802.11 a/b/g/n Wi-Fi adapter and a video de- and encoder in hardware.

Qualcomm Snapdragon 439

The Qualcomm Snapdragon 439 (SD439) is a lower mainstream SoC for (Android based) smartphones and tablets. Compared to the older Snapdragon 435, the 439 is now manufactured in the current 12nm FinFET process and offers higher clock speeds of 2 GHz of the eight ARM Cortex-A53 cores (compared to 1.4 GHz). Wifi (now ac Wave 2 / Wifi 5) and Bluetooth (v5) were also updated, however the GPU still is the rather slow Adreno 505 and the LTE modem was even downgraded to a X6 with only Cat. 4/5 (max. 150 Mbps download, 75 Mbps upload).

Thanks to the higher maximum clock speed, the performance of the Snapdragon 439 mobile platform can reach the old Snapdragon 625 (also 2 GHz with 8x Cortex-A53). However, there is still a big gap to the SoCs with bigger performance cores.

Qualcomm Snapdragon 435

The Qualcomm Snapdragon 435 (SD435) 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 X9 LTE modem supports Cat. 4 with maximum transfer rates of 300 Mbps (downstream) and 100 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). The main difference to the Snapdragon 430 is the faster LTE modem.
