Mediatek Helio G99 vs MediaTek Dimensity 9000

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 9000

The MediaTek Dimensity 9000 is a high-end SoC with an integrated 5G modem. It includes one fast Cortex-X2 core with up to 3 GHz, three more A710 cores with up to 2.85 GHz and four power efficiency cores (Cortex-A510) with upto 1.8 GHz. The SoC is manufactured in the new 4nm process at TSMC. All CPU cores can together use 8 MB of level 3 cache and 6 MB of System Level Cache (SLC).

The integrated quad channel memory controller supports LPDDR5X with 7500 Mbps. The integrated GPU is an ARM Mali-G710 MC10 (10 of the 16 possible cores).

The Dimensity 9000 is one of the first chips to be produced in the modern 4nm process at TSMC
