MediaTek Dimensity 820 vs MediaTek Dimensity 800U vs UNISOC T765

MediaTek Dimensity 820

The Mediatek Dimensity 820 is a fast mid-range SoC with an integrated 5G modem. It includes four fast ARM Cortex-A76 cores at up to 2.6 GHz and four power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 5 core ARM Mali-G57 MC5 GPU, a Wi-fi 5 modem, a LPDDR4x memory controller, a AI processing unit (APU 3.0) and video de- and encoding. The Dimensity 820 is manufactured in the modern 7nm process and should be very power efficient.

MediaTek Dimensity 800U

The Mediatek Dimensity 800U is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A76 cores at up to 2.4 GHz and six power efficient Cortex-A55 cores at up to 2 GHz (Octa-Core with Heterogeneous Multi-Processing). Furthermore, the chip integrates a 3 core ARM Mali-G57 MC3 GPU, a Wi-fi 5 modem, a LPDDR4x memory controller, a AI processing unit (APU 3.0) and video de- and encoding.

Compared to the Dimensity 820, the 800U offers lower clocked A76 cores and a slower GPU.

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

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).
