Qualcomm Snapdragon 435 vs Mediatek Helio P20 (LP4) MT6757

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.

Mediatek Helio P20 (LP4) MT6757

The Mediatek Helio P20 MT6757 is an upper mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2016. It is manufactured in a 16 nm FinFET process and is equipped with 8 ARM Cortex-A53 CPU cores clocked at 2.3 GHz (max.). The chip also includes an LTE modem (Cat. 6).

The integrated ARM Mali T880 MP2  GPU is clocked at up to 900 MHz and has two cluster (from 16) from the Midgard (4th Gen) architecture.
