Mediatek Helio G25 vs Qualcomm Snapdragon 429 vs Qualcomm Snapdragon 450

Mediatek Helio G25

The Mediatek Helio G25 is an entry level ARM SoC for smartphones (mainly Android based) that was introduced in late 2020. It is manufactured in a 12 nm FinFET process and is equipped with 8 ARM Cortex-A53 CPU cores divided in two clusters. A performance cluster with 4 cores clocked at up to 2 GHz and a efficiency cluster clocked at up to 1.5 GHz. Compared to the similar Helio A25, the G25 clocks the GPU (+50 MHz) and the CPU cores higher (+200 MHz).

Furthermore, the SoC integrates a LTE Cat.4 modem, a LPDDR3-933 / LPDDR4-1200 / LPDDR4x-1600 memory controller, a IMG PowerVR GE8320 graphics card and a 1080p30 video de- and encoder (H.265 decoding, H.264 encoding).

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.

Qualcomm Snapdragon 450

The Qualcomm Snapdragon 450 (SD450) is a lower mainstream SoC for (Android based) smartphones and tablets. It features eight ARM Cortex-A53 cores at up to 1.8 GHz and is already manufactured in the power efficient 14nm process. The integrated X9 LTE modem supports Cat. 7 with maximum transfer rates of 300 Mbps (downstream) and 150 Mbps (upstream). The SoC also includes an Adreno 506 GPU with support for Vulkan and OpenGL ES 3.1. WiFi 802.11ac (1x1, max 364 Mbps) and Bluetooth 4.1 are supported as well. The memory controller supports LPDDR3 (single channel) and the integrated video engine supports H.264 (encode and decode) and HEVC (only decode) in 1080p.
