Unisoc T9100 (T820) vs Qualcomm Snapdragon 888 4G

Unisoc T9100 (T820)

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.

Qualcomm Snapdragon 888 4G

The Qualcomm Snapdragon 888 4G Mobile Platform is a high-end SoC for smartphones that was introduced in mid 2021 and manufactured in 5 nm at Samsung. Compared to the earlier released Snapdragon 888 5G, the 4G variant only features a 4G LTE modem.

The chip integrates one “Prime Core” based on a ARM Cortex-X1 architecture clocked at up to 2.84 GHz. Three more performance cores are based on the A78 but clock up to 2.42 GHz. Furthermore, four energy saving cores are integrated that are based on the ARM Cortex-A55 architecture and clock at up to 1.8 GHz. In addition to the processor cores, the SoC integrates a WiFi 6e modem, a Hexagon 780 DSP (up to 26 TOPS of AI performance) and a Spectra 580 ISP. The integrated memory controller now supports faster LPDDR5 memory with up to 3,200 MHz. 

The performance of the processor cores should be around 15% better than the old Snapdragon 865+. The integrated Adreon 660 GPU should make a bigger jump by 35% (most likely compared to the SD 865).
