Qualcomm Snapdragon 450 vs Samsung Exynos 1380 vs Qualcomm Snapdragon 625

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.

Samsung Exynos 1380

The Samsung Exynos 1380 is a system on a chip (SoC) designed for mid-range smartphones and tablets running on the Android operating system. The CPU is made up of two clusters, each consisting of four cores. It features four Cortex-A78 performance cores (up to 2.4 GHz) and four Cortex-A55 power-saving cores (up to 2.0 GHz). The integrated graphics unit is an ARM Mali-G68 MP5 with speeds of up to 950 MHz.

The NPU's performance has been improved by around 14 percent compared to its predecessor, with a capacity of 4.9 TOPS. Displays with up to 144 Hz and Full HD+ resolution can now be used, and the chipset supports cameras with up to 200 MPix. The chipset also includes Wi-Fi 6 and Bluetooth 5.3. Both LPDDR4x and LPDDR5 can be used as RAM, and UFS 3.1 is possible as internal storage.

The integrated modem has significantly increased download speeds, supporting both 5G-Sub6 (download: up to 3.79 Gbps (+32%), upload: up to 1.28 Gbps) and 5G-mmWave (download: up to 3.67 Gbps (+75%), upload: up to 0.92 Gbps). The upload speed for LTE (Cat. 18, download: up to 1.2 Gbps, upload: up to 0.211 Gbps (+5%)) has only been slightly improved.

The Exynos 1380 is manufactured by Samsung using the 5-nm process.

Qualcomm Snapdragon 625

The Qualcomm Snapdragon 625 (SD625) is a mid-range octa-core SoC with eight ARM Cortex-A53 cpu cores at up to 2 GHz, an Adreno 506 GPU, a DDR3L-1866 memory controller and a X9 LTE (Cat 7, 4G+, 300 Mbps down, 150 Mbps up) modem. Furthermore, the chip supports 802.11ac WiFi and Bluetooth 4.1. It is manufactured in 14nm FinFet. The processor performance should be similar to a HiSilicon Kirin 650, which also offers 8 Cortex A53 cores at up to 2 GHz. However, due to the modern manufacturing process, power consumption and throttling should be better with the Snapdragon 625.
