Mediatek Helio G70 vs Mediatek Helio G99 vs Mediatek Helio G81 Ultra
Mediatek Helio G70
► remove from comparison
The Mediatek Helio G70 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 1.7 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 820 MHz. The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.
Compared to the slightly faster Helio G80, the difference to the G70 is the slightly lower clock speed for the A55 cores (-100 MHz) and GPU (-130 MHz).
The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
Mediatek Helio G99
► remove from comparison
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.
Mediatek Helio G81 Ultra

The Mediatek Helio G81 Ultra is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 2 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 950 MHz. The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.
Compared to the old Helio G80, the G81 offers support for 120Hz displays.
The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
