Mediatek Helio G99 vs UNISOC T616 vs UNISOC T619

Mediatek Helio G99

The Mediatek Helio G99 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2022. It is manufactured in a 6 nm FinFET process and is equipped with 2x big ARM Cortex-A76 cores with up to 2.2 GHz and 6x small and power efficient ARM Cortex-A55 cores (max. 2 GHz) in two clusters (bigLITTLE). The chip integrates an ARM Mali-G57 MC2 (two cores). Compared to the older Helio G96, the G99 is manufactured in the more recent 6nm process and clocks higher.

Furthermore, the integrated LTE / 4G modem supports Cat-13 download speeds. Wi-Fi 5 is also integrated (a/b/g/n/ac). The memory controller supportsLPDDR4x with up to 4,266 Mbps.

UNISOC T616

The Unisoc Tiger T616 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2 GHz and six power efficient ARM Cortex A55 cores at up to 1.8 GHz. The SoC furthermore includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR4x 1866 MHz memory controller and an ARM Mali G57MP1 GPU (750 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured at TSMC in 12nm FinFET. 

UNISOC T619

The Unisoc Tiger T619 (former Spreadtrum) is an entry level octa core SoC with two fast ARM Cortex A75 cores at up to 2.2 GHz and six power efficient ARM Cortex A55 cores at up to 1.8 or 2 GHz. The SoC furthermore includes an LTE modem (TDD-LTE, FDD-LTE, TDSCDMA, WCDMA, CDMA, GSM), a LPDDR4x 1866 MHz memory controller and an ARM Mali G57MP1 GPU (850 MHz max) and a dual core ISP (24 and 8 MPixel support). The chip is manufactured at TSMC in 12nm FinFET. 

Compared to the T616, the T619 offers 200 MHz higher clocked A75 cores and a 100 MHz higher clocked GPU.
