Mediatek Helio G99 vs Mediatek MT8788
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 MT8788
► remove from comparison
The Mediatek MT8788 is an upper mainstream ARM SoC for smartphones (mainly Android based) that was introduced in early 2018. It is manufactured in a 12 nm FinFET (12FFC) process and is equipped with 4x big ARM Cortex-A73 cores and 4x small and power efficient ARM Cortex-A53 cores in two clusters (bigLITTLE). The cores can reach a frequency of up to 2 GHz. The processor also integrates a ARM Mali-G72MP3 GPU and a dedicated AI processing unit. Furthermore, the integrated radio Wifi 802.11ac, Bluetooth 4.2, and FM radio. The specifications of the MT8788 are identical to the Helio P60 for Smartphones.
