Mediatek Helio G99 vs MediaTek Dimensity 8020

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.

MediaTek Dimensity 8020

The MediaTek Dimensity 8020 is a ARM-based System-on-a-Chip (SoC) similar to the older Dimensity 1100. It was specifically designed for use in Android smartphones and falls into the mid-range category in terms of performance. It supports all current mobile network standards, including 5G with 2CC-CA (200MHz) and FDD+TDD.

The CPU consists of a total of eight cores divided into two clusters. One cluster has four ARM Cortex-A78 performance cores with speeds of up to 2.6 GHz, while the other cluster has four ARM Cortex-A55 power-efficient cores with speeds of up to 2.0 GHz. LPDDR4 RAM can be used as the memory, and it supports UFS 3.1 as the internal storage.

In terms of connectivity, it offers Dual-5G support, as well as Wi-Fi 6 and Bluetooth 5.2.

The integrated graphics unit, ARM Mali-G77 MC9, can power displays with a resolution of up to 2560 x 1080 and a refresh rate of up to 144 Hz (possibly only for Full HD+).

The chip is manufactured by TSMC using the current 6nm process in the mid-range segment.
