Unisoc T9100 (T820) vs MediaTek Dimensity 900
Unisoc T9100 (T820)
► remove from comparison
The Unisoc T9100 (formely Unisoc T820) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with three clusters. One fast ARM Cortex-A76 clocked at up to 2.7 GHz, three more A76 performance cores clocked at up to 2.3 GHz and a power efficiency cluster of four ARM-Cortex-A55 cores with up to 2.1 GHz. The integrated memory controller supports LPDDR4/4X with up to 2133 MHz (2x 16 Bit). The integrated ISP supports two main cameras and two subsidiary cameras (up to 108 MPix). The integrated graphics card is an ARM Mali-G57 MC4 (4 cores) at up to 850 MHz. Unisoc also specifies that the T9100 offers hardware AI acceleration with up to 8.0 TOPS peak performance of the NPU.
The chip is manufactured on the modern 6nm EUV process.
MediaTek Dimensity 900
► remove from comparison
The Mediatek Dimensity 900 is a fast mid-range SoC with an integrated 5G modem. It includes two fast ARM Cortex-A78 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 4 core ARM Mali-G68 MC4 GPU, a Wi-fi 6 modem, a LPDDR4x memory controller, a AI processing unit and video de- and encoding.
The Dimensity 900 is manufactured in the modern 6nm process and should be very power efficient.
