Qualcomm Snapdragon 430 (MSM8937) vs Mediatek Helio A20 MT6761D vs Qualcomm Snapdragon 429

Qualcomm Snapdragon 430 (MSM8937)

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). 

Mediatek Helio A20 MT6761D

The Mediatek Helio A20 MT6761D is an entry-level ARM SoC for smartphones and tablets (mainly Android-based) that was introduced in 2020. It integrates four ARM Cortex-A53 cores clocked at up to 1.8 GHz. It integrates a PowerVR GE6300 GPU clocked at up to 550 MHz. The integrated memory controller supports LPDDR4x (max. 4 GB at 1200 MHz). Furthermore, a LTE radio with Cat-4 DL (150 Mbps download) and Cat-6 UL (50 Mbps upload) and a 802.11 a/b/g/n/ac Wi-Fi 5 modem is integrated.

Compared to the similar named A22 MT6761, the MT6761D offers lower clocked CPU and GPU cores and a slower LTE modem, but is produced in the modern 12 versus 16nm process.

Qualcomm Snapdragon 429

The Qualcomm Snapdragon 429 is an ARM-based entry level SoC for tablets and smartphones (mostly Android based). It was announced in mid 2018 and integrates four 64-Bit Cortex-A53 CPU cores (quad-core) that clock with up to 2 GHz. Furthermore, there is a Adreno 504 graphics card, a LPDDR3 memory controller (max. 933 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 addressing 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 504 ist the integrated graphics card that supports OpenGL ES 3.1 / 3.2 and Vulkan 1.0. According to Qualcomm, the GPU is 50% faster than the previous Adreno 308 in the Snapdragon 425.

The integrated wireless radios support WiFi 802.11ac Wave 2, Bluetooth 5.0, GPS/GLONASS/Baidou, 2G, 3G and 4G (LTE Cat.4 / Cat.5 - 150 Mbits download, 75 Mbits upload) 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 the modern 12nm process.
