Samsung Exynos 7885 vs UNISOC T765 vs MediaTek Dimensity 800

Samsung Exynos 7885

The Samsung Exynos 7885 (also called Exynos 7 Series) is a upper mid-range system-on-a-chip (SoC) for smartphones and tablets. It was launched early 2018 alongside the Samsung Galaxy A8 2018 series and features two Cortex-A73 cores clocked at up to 2.2 GHz. Furthermore, there are six power efficient Cortex-A53 cores at up to 1.6 GHz, an ARM Mali-G71 MP2 GPU and a LPDDR4x memory controller. The integrated LTE modem supports LTE Cat.12 3CA 600 Mbps download speeds and Cat.13 2CA 150 Mbps upload. 802.11ac WiFi, Bluetooth 5.0 and FM Radio are also in the chip. It is manufactured in 14nm FinFET at Samsung and therefore a rather power efficient SoC.

UNISOC T765

The UniSoc T765 is a mid-range SoC with 8 processor cores in two clusters. The two large ARM Cortex-A76 cores are clocked at up to 2.3 GHz. The six smaller cores run at up to 2.1 GHz.

The integrated memory controller supports LPDDR4/4X with up to 2133 MHz (2x 16 bit). The integrated ISP supports a camera up to 108 MPixel. The integrated graphics card is an ARM Mali-G57 MC2 (2 cores) is used. The built-in 5G modem supports TDD+FDD CA in the sub-6GHz spectrum with 130 MHz bandwidth.

The chip is manufactured using the somewhat older 6nm process (EUV at TSMC).

MediaTek Dimensity 800

The Mediatek Dimensity 800 is a fast mid-range SoC with an integrated 5G modem. It includes four fast ARM Cortex-A76 cores at up to 2 GHz and four power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 4 core ARM Mali-G57 MC4 GPU, a Wi-fi 5 modem, a LPDDR4x memory controller(up to 16 GB with 2133 MHz), a AI processing unit (APU 3.0) and video de- and encoding.

Compared to the similar named Dimensity 800U, the 800 offers two more big A76 cores but clocked 400 MHz lower. This means the single core performance is lower, but the multi-core performance can be better.

The Dimensity 800 is manufactured in the modern 7nm process and should be very power efficient.
