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.
