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.
The Allwinner A523 is a very affordable ARM-based SoC for smartphones and tablets. The eight-core processor presented in 2023 consists of two quad-core clusters, each made up of 4 Cortex-A55 cores.
The faster quad cluster operates at a clock frequency of up to 1.8 GHz and offers 128 KB L2 cache per A55 core, while the second cluster clocks at up to 1.4 GHz and only offers 64 KB L2 cache per core.
In another version of the Allwinner A523, the first quad cluster clocks at up to 2.0 GHz. The ARM Mali-G57 MC1 is used as the graphics unit, which supports OpenGL 3.2, Vulkan 1.0 and OpenCL 2.0. A XuanTie E906 RISC-V PMU is also integrated.
The Allwinner SoC can control up to 4 GB DDR3/DDR4/LPDDR2/LPDDR3/LPDDR4/LPDDR4X RAM and eMMC 5.1 flash memory. In addition to PCIe 2.1, USB 3.1 Gen. 1 and Gigabit Ethernet are also supported as interfaces. There is also an H264/H265 video decoder (up to 4K at 60 frames per second) and an H264 encoder (up to 4K at 25 frames per second).
The Allwinner A523 is manufactured with a 22 nm structure width.
