Broadcom BCM21664T vs UNISOC Tiger T310

Broadcom BCM21664T

The Broadcom BCM21664T is an ARM based entry-level SoC for smartphones that integrates two Cortex-A9 CPU cores clocked at up to 1.2 GHz and a HSPA+ modem with support for 21 Mbps HSDPA and 5.8 Mbps HSUPA. Furthermore, a VideoCore-IV GPU and a video decoder (H.264 1080p capable) and encoder (720p) are built into the SoC.

UNISOC Tiger T310

The Unisoc Tiger T310 is a SoC for smartphones and tablets of the entry level. It was first announced in mid 2019 and integrates four CPU cores (quad core). One big Cortex-A75 core clocked at up to 2 GHz and three small A55 cores with up to 1.8 GHz.

Furthermore, the chip integrates an LTE modem (Cat 7, TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), Bluetooth 5.0 and WiFi b/g/n/ac. The integrated ISP supports up to two cameras (16 MPixel and 8 Mpixel, maximum 30 fps video capture) and the GNSS can use all current standards (GPS, Glonass, Beidou, Galileo).

The memory controller is able to drive LPDDR3 at 933 MHz and faster LPDDR4x at 1333 MHz.

The PowerVR GE8300 iGPU is from Imagination and clocked at up to 800 MHz.

The chip is produced in 12nm at TSMC and should offer a rather good power efficiency (for 2019).
